Why Is Aluminum Used for Aircraft Bodies

 Why is aluminum used for aircraft bodies? Aircraft aluminum alloys have many excellent properties such as high toughness, corrosion resistance and fatigue resistance. Since the early 20th century, they have been widely used in the aviation field as the fuselage skin, beams, stringers,etc. According to the difference in the service performance and use of the aircraft, the amount and specifications of aluminum alloys on the aircraft are also quite different.

7xxx aluminum alloy is another commonly used alloy with a wide variety. It contains zinc and magnesium. The most common aluminum alloy with the best strength is 7075 aircraft aluminum. How about aluminum alloy 7075 properties?

7075 aluminum alloy is a cold-worked wrought alloy, one of the strongest commercially available alloys. It has normal corrosion resistance, good mechanical properties and anodic reaction. The finer grains result in better deep drilling performance, enhanced tool wear resistance and distinctive thread rolling.

7075 mainly contains zinc element, which is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. It is a super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress relieved and will not deform or warp after processing. All super-large and super-thick 7075 aluminum plates are ultrasonically detected, which can ensure no blisters and impurities. 7075 aluminum plate has high thermal conductivity, which can shorten the forming time and improve work efficiency.

After solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength, poor welding performance, and tendency to stress corrosion cracking.

7075 aluminum plate is generally added with a small amount of copper, chromium and other alloying element. Among this series, the 7075-T651 aluminum alloy is known as the best product in aluminum alloys. This alloy also has good mechanical properties and anodic reaction.

Car Aluminium 6016 vs 6061

 The car body is the heaviest part in the car, accounting for about 30% of the car's weight, so the aluminization of the car body plays a pivotal role, and the development of aluminum alloy materials for the car body is the key. 6xxx aluminum alloy is a main alloy for automobiles including Al6016 and 6061.

6016 aluminum alloy has the advantages of good fracture toughness, corrosion resistance, fatigue resistance, etc., and has a wide range of uses in aviation, aerospace, ships, transportation and construction. It is mainly used for the manufacture of doors, windows and invisible parts in the body structure.

Hemming is an important process in the assembly and pressing process of the inner and outer panels of automobile body panels. An important indicator to measure the performance of 6016 aluminum plate hemming is the bending limit. Generally speaking, the 6016 aluminum plate in O state is the softest and suitable for various bending shapes.

The main alloying elements of alum 6061 are Mg and Si, and form the Mg2Si phase, which is one of the most widely used aluminum alloys. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance.

Alum 6061 has good strength and toughness, excellent machinability, corrosion resistance and ideal anodizing effect after being treated and pre-stretched. After special treatment (T6), 6061 alloy achieves medium strength, and its strength is higher than that of 5 series alloys. It is often used to make fenders, car hood outer panel and card doors.

At present, the 6061 aluminum plate technology in China is relatively mature. Haomei Aluminum is one of the big aluminum sheet manufacturers. Our 6061 aluminum sheet thickness is of 0.2-500mm and a maximum width is of 2800mm. The common tempers are T6 and T651. Welcome to leave message below to inquire what you need.

The Hot Rolling 5083 Cast Aluminum Plate

 5xxx aluminum plate belongs to the more commonly used alloys. The main alloying element is magnesium and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. 5083 cast aluminum plate belongs to the hot rolled aluminum plate. The hot rolling enables the 5083 aluminum sheet have high corrosion resistance and fatigue resistance.

The hot rolling is to undergo more than 90% thermal deformation. During the process of large plastic deformation, the internal structure has undergone multiple recovery and recrystallization, and the coarse grains in the casting state are broken and the micro-cracks are healed, so the casting defects can be significantly improved.

Types of hot rolled products

1. Hot-rolled thick plates: It refers to the aluminum plates with a thickness of not less than 7.0 mm. The main varieties are hot-rolled plates, annealed plates, quenched or quenched pre-stretched plates. The traditional process is: ingot homogenization - milling surface - heating - hot rolling- cut to size- straightening.

2. Hot-rolled aluminum coil: Aluminum and aluminum alloy sheets and strips with a thickness of less than 7.0 are usually produced by hot-rolled coils.
Hot rolling Process of 5083 aluminum plate

1. Preparation before hot rolling includes ingot quality inspection, soaking, sawing, milling, aluminum coating and heating.

2. During semi-continuous casting, the cooling rate is very high, the diffusion process in the solid phase is difficult, and the ingot is easy to have uneven structure, such as intragranular segregation.

3. When there are defects such as segregation, slag inclusion, scarring and cracks on the surface of the ingot, milling should be carried out. It is an important factor to ensure good surface quality of the finished product.

4. The hot rolling of aluminum alloy ingots is to provide billets for cold rolling, or to directly produce thick plates in hot rolled state.
