Aircraft Aluminum Alloy 7075 T6

 In the selection of materials for the C919 aircraft, a large number of traditional aluminum alloys are selected, such as 7075-T62, 7075-T73, 7050-7452, 7075-T73511, 7050-T77511, 7075-T7351, 7050-T7452, 7150-T77511, 7075- T6, 7055-T7751, 7055-T76511, 7085-TT651, 7085-T7452; 2024-T42, 2523-T3, 2024-T3511, 2024HDT-T351, 2026-T3511, etc.

Aluminum alloy 7075 is mainly used in the manufacture of aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing panels, stringers, etc. After solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength.

Zinc is the main alloying element in the 7075 aluminum plate. The addition of magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, so that the heat treatment effect of the alloy is far better than that of the aluminum-zinc binary alloy.

The common tempers of 7075 aluminum sheet are T651, T6, T73, T76 and T74. Among the series, the 7075-T651 aluminum alloy is of the highest grade, and is known as an excellent product among aluminum alloys, with high strength far superior to any mild steel. What are 7075-t6 aluminum properties?

T6 temper has the highest strength, low fracture toughness, and is sensitive to stress corrosion cracking. Generally, it is not recommended for low temperature applications. The T73 process successfully developed in 1960 is an over-aging heat treatment process.

Compared with the T6 state, the material strength is reduced by 10%~15%, but it can effectively prevent stress corrosion cracking in the thickness direction, and has high fracture toughness and excellent stress corrosion resistance and exfoliation corrosion resistance performance.

Much like the 7075 aluminum alloy, the 2024 aluminum alloy is commonly used in aerospace applications. In particular, it is commonly used in aircraft wings and fuselages. 2024 aluminumis suitable for applications requiring high cyclic fatigue strength; while 7075 is suitable for applications requiring high stress/strain resistance.

Both alloys offer similar weldability. Spot or flash welding can be used, but arc and gas welding are not recommended. They all have similar machinability. 2024 has slightly better machinability and 7075 has slightly better corrosion resistance.

Marine Grade Aluminum VS Aluminum

 Compared with common aluminum alloys, the marine grade aluminum has better corrosion resistance. Al-Mg alloy is the most widely used marine grade aluminum, which has lower density than common aluminum, excellent resistance to marine climate and seawater corrosion, weldability and polishability, and excellent plasticity (Mg≤5% ), as well as good seismic performance, and higher fatigue strength than tat of duralumin.

In the chemical composition of aluminum-magnesium alloys used in marine engineering, the maximum magnesium content of 5052 alloy with low magnesium content is only 2.8%, and the content of 5083 alloy with the highest magnesium content is 4.9%. Although the strength of aluminum alloy increase due to the increase of Mg content, the plasticity and corrosion resistance decrease significantly, especially for alloys with Mg>6%.

Deformed aluminum alloys used in marine engineering include 5052 (5A02), 5252, 5154, 5454, 5754, 5083, 5086, 5059,etc. Among them, the magnesium content of the 5052 alloy is the lowest, the second group is 5154, 5454 and 5754 alloys, the magnesium content of the 5083 alloy is moderately high, 5059 aluminum has the highest magnesium content.

5059 aluminum plate is a 5xxx Al-Mg aluminum alloy with good corrosion resistance and tensile strength. It has excellent overall performance and is currently recognized as the most technically difficult high-end marine aluminum alloy, which is widely used in ships, oil tankers and other fields.

A new generation of marine engineering deformed aluminum alloy 5059 was developed in 1999 by Crus Aluminum Company (now Aleris Aluminum Company) and registered with the American Aluminum Association (AA). It is an excellent marine engineering aluminum alloy. The alloy has been used in the manufacture of cruise ships and various ships that can carry 7,000 passengers, as well as LNG ship.

Compared with the traditional 5083 alloy, the impurity Si, Fe, and Mn contents of 5059 aluminum are slightly higher, and the average content of Mg is 24% higher than that of the 5083 alloy. Zn is an impurity in 5083 alloy, but it is a trace alloying element in 5059 alloy, and 5059 alloy also contains 0.05% Zr~0.25% Zr.

Due to these differences in composition, the properties of aluminum 5059 are overall better than those of alloy 5083, but but due to its high magnesium content, its press working and forming properties are slightly inferior. Welcome to leave message below to inquire what you need.

5052 Aluminum Cut to Size for Automobile

 Generally speaking, car aluminium is mainly used in three aspects: automobile wheels, automobile engine gearbox and body in white. There are also other uses like interior trim and bottom plate. The common aluminum alloy for automobile body include 2xxx, 5xxx and 6xxx. Different types of aluminum alloy materials are used for different stress parts.

Among the many aluminum alloys, the 5 series and 6 series aluminum alloys have excellent performance in the field of automobile manufacturing, especially 5052 aluminum cut to size. It is a widely used rust-proof aluminum plate with high strength, especially fatigue resistance, high plasticity and corrosion resistance, good weldability,etc.

5052 Aluminum sheet is a kind of aluminum alloy that cannot be strengthened by heat treatment. It is suitable for parts with complex shapes such as the inner panel of the body, and can also be used for automobile skins, doors, automobile engine outer plates, automobile fuel tanks, etc. Why can 5052 aluminum used for cars? Lets have a look of 5052 aluminum properties.

Stretching performance

There are various processing methods for aluminum sheets in the process of use, including stretching. Aluminum sheets are stretched and then made into aluminum products and aluminum accessories. 5052 alloy often needs to be stretched during use.

Good surface flatness

The aluminum sheet must have good flanging ductility and the performance of consistent surface color after forming, that is, there is no roping line on the surface of the formed sheet metal part. It is the uneven surface deformation of the sheet caused by uneven grains or uneven distribution of inclusions, so that the surface appears inconsistent in luster after painting.

Good weldability

It can meet the welding requirements of automotive components after forming. The sheet should have anti-aging stability to ensure that aging does not occur from the factory to the stamping production, and prevent the yield point of the material from rising during stamping, which will induce uneven surface deformation and wrinkling, thereby affecting the surface quality of automobile outer panels. .

Excellent bake hardenability

The lightweight of automobiles also requires high bake hardenability of the aluminum sheet, that is, the yield strength of the sheet is significantly increased after stamping deformation and paint baking, so as to ensure that the sheet metal parts after stamping and painting have high dent resistance.

En Aw 5083 h321 Used in Different Types of Tanker

 Tanker types include oil tanker, cement tanker, natural gas tanker, sprinkler and so on. These large tank trucks are going through a stage of transition from steel to aluminum. At present, aluminum alloy load tankers have an increasing proportion in the market. EN AW 5083h321 aluminum is s the most important alloy material for aluminum tankers.

Tanks for transporting aviation gasoline and jet kerosene must be welded with aluminum alloys, because even if stainless steel tanks are used, a very small amount of iron will enter the oil, which is not allowed.

The section of the cylinder is a circular arc rectangle, which is based on the consideration of lowering the center of gravity of the vehicle and increasing the cross-sectional area within the range of the vehicle's external dimensions. 5083 alloy is used for welding, and the plate thickness is 5mm~6mm.

The 16t oil tanker developed by Japan's Mitsubishi Motors, except that the tank is welded with aluminum alloy plates, its frame (11210mm×940mm×300mm) is made of aluminum alloy profiles, which is 320kg lighter than the steel frame. The whole vehicle is reduced by 1.5t.

The biggest difference between aluminum and steel in the relationship between properties and temperature is that steel has low temperature brittleness, while aluminum and aluminum alloys do not. Therefore, aluminum alloy becomes a good material for the manufacture of low-temperature equipment and facilities. The tank truck for transporting LNG and the large tank for storing LNG can be welded with 5083-O aluminum sheet.

The cylinder of the aluminum alloy tanker is the core material of the aluminum alloy tanker. The amount of oil to be filled is determined by the size of the tanker body. It is usually made of 5083 h321 aluminum plate cut to size. The aluminum sheet thickness is usually 6mm. Multiple aluminum alloy sheets are connected together by a can rolling machine and fixed by double-sided welding.

What Is The Market Prospect of Battery Hack Aluminum Foil

 

According to GGII statistics, the global sales of new energy vehicles in the first half of 2021 were 2.252 million, an increase of 151%, and the installed capacity of power batteries was about 100.49GWh, an increase of 141%.

New energy vehicles drive power batteries to grow rapidly. It is estimated that the global sales of new energy vehicles will exceed 5 million in 2021, driving the installed capacity of power batteries to exceed 250GWh.

As the main technical route of electrochemical energy storage, lithium-ion energy storage batteries have the characteristics of high energy density, high comprehensive efficiency, great potential for cost reduction, short construction period and wide applicability, etc.

We expect lithium battery shipments to reach 1,135.4GWh, including 873.6GWh of power batteries, 94.3GWh of 3C digital batteries, and 167.5GWh of energy storage batteries. Correspondingly, the demand for battery hack aluminum foil in 2025 will reach 454,200 tons to 681,200 tons.

Similar to the lithium battery copper foil, the battery aluminum foil is the key material for the current collector of the lithium battery cathode material. Its main function is to collect the current generated by the battery active material and output the current. In order to obtain a lithium battery with better performance, it is required that the conductive current collector should be in full contact with the active material, and the internal resistance should be as small as possible.

Due to its good electrical conductivity, soft texture, mature manufacturing technology, and outstanding cost advantages, aluminum foil has become the first choice for lithium-ion battery cathode current collectors. At present, the thickness of the current collector aluminum foil of lithium battery is 9-20 μm.

The battery aluminum foil is used as the current collector of lithium ion batteries. The use of this type of aluminum foil can greatly reduce the contact resistance between the positive/negative electrode material and the current collector, and improve the adhesion between the two, thereby significantly improving the battery life of pure electric vehicles and hybrid vehicles.

As the energy density of the power battery increases, the thickness of the aluminum foil as the current collector is getting thinner and thinner, and the production requirements are higher.

Generally speaking, the strength requirement is inversely proportional to the thickness, and the battery foil needs to increase the strength in order to reduce the thickness of the aluminum foil and provide conditions for increasing the energy density. Most battery hack aluminum foil customers require the thickness standard of aluminum foil products to be in the range of ±2%.

At present, most of the online thickness control systems of aluminum foil rolling mills are difficult to meet this requirement. This thickness accuracy requirement is the highest among all aluminum foil products at present, and the process barrier is relatively high. Generally speaking, the technological difficulty of battery foil is reflected in thickness requirements, thickness accuracy requirements, strength, surface dyne value, etc.

As a big aluminum foil sheet manufacturer, Haomei Aluminum can reach a balance between the thinnest thickness, the highest strength, the highest dyne value, the smallest thickness difference, the best shape and the cleanest surface. Welcome to leave message below to inquire what you need.
