The History of Aviation Grade Aluminum

 Aviation grade aluminum has 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 basic fulsage maerial. The skins, beams, stringers and other equipment components on the aircraft are all made of aluminum alloys.

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. For example, the aerospace aluminum alloy material on the Boeing 767 passenger plane accounts for about 80% of the total weight of the aircraft, while the military F-15 fighter aircraft uses only about 35% of the aluminum alloy to ensure the flight speed and combat performance.

Development history of aviation aluminum alloy

Metal elements such as zinc, magnesium, copper, lithium, and manganese are added to elemental aluminum through a series of processes to obtain aluminum alloy. For example, the Wright Brothers used Al-Cu alloys to machine crankcases for aircraft engines in the early 20th century.

It can be said that the development of aluminum alloy materials is not only affected by material synthesis technology, but also promoted by the needs of aircraft aviation performance. Under the interaction of the two, the development of aluminum alloy materials is mainly divided into the following four stages.

1. High static strength aluminum alloy

In the early stage of the development of the aviation field, the aircraft design only considered the static strength during flight. The main body and parts of the aircraft were made of high-static-strength aluminum alloy materials. The typical alloys are 2014, 2024-T3, 7075-T6, 7178-T6,etc. These alloys were widely used in civil and military aircraft from the 1940s to the 1960s.

2. Corrosion-resistant aluminum alloy

In 1985, a Boeing 747 crashed due to stress corrosion cracking, killing more than 500 people. In this period, the design of aluminum alloy materials no longer simply considers static strength, but additionally considers its corrosion resistance. On the basis of 7075-T6, the aging heat treatment process was used to successfully develop 7075-T73 which is resistant to stress corrosion.

Later, 7075 aluminum plate in T76 state was further developed, which not only obtained stronger corrosion resistance, but also sacrificed a lower static strength than 7075-T73, improving the comprehensive performance of aluminum alloy materials and became the best corrosion-resistant aluminum alloy.

3. High strength and high toughness aluminum alloy

Based on the requirements of aircraft fail-safe design, aircraft design not only needs to consider the static strength and corrosion stress of materials, but also puts forward higher requirements for fracture toughness. The high-strength 7050 aluminum alloy was successfully developed. The alloy has been successfully applied to the wing structure of Boeing 757 airliners.

4. Aluminum alloy with high comprehensive performance

Since the 1980s, from the perspective of design safety, the design of aircraft materials should not only consider static strength, stress corrosion and toughness, but also include the residual strength of the main structure after damage. 7150-T77, 7055-T77 and 2524-T3 have been developed and applied to advanced aircraft such as F-35 and B777.

6111 Alumium for Car Body

 With the rapid development of the automobile industry, the resulting problems of energy consumption and environmental pollution have become more and more serious. As an effective way to reduce the fuel consumption rate of automobiles and save energy, the lightweight of automobiles has become the trend of the development of the world automobile industry.

There are two ways to reduce the weight of automobiles: one is to optimize the car frame structure; the other is to use lightweight materials. The practice of industrialized countries shows that the former has little potential to be tapped, so the automobile industry generally focuses on the development of lightweight materials to solve this problem.

Among high-strength and light-weight materials, composite materials are difficult to recycle and cause environmental pollution. Magnesium alloys limit their application in automotive body panels due to their poor corrosion resistance and formability.

Aluminum alloy has the characteristics of light weight, wear resistance, corrosion resistance, high specific strength, good impact resistance, easy surface coloring, etc., and more than 80% of aluminum can be recycled and reused, making aluminum alloy an ideal lightweight material for automobiles.

Since the 1970s, developed countries in the automobile industry such as Europe, America and Japan have developed several 6xxx aluminum alloys such as 6009, 6010, 6016, 6111, and 6022. In the early 1980s, North America and Europe respectively developed high-Cu 6111 aluminum and low-Cu 6016 aluminum alloy.

On the basis of 6010 aluminum alloy, the paint hardening and formability of 6111 aluminum alloy were significantly improved, and the 6111 aluminum alloy has higher strength after being treated with baking hardening.

At present, the 6XXX aluminum for car body are mainly 6016, 6111, and 6022 aluminum alloys. European automakers mostly use low-Cu 6016 aluminum alloy with good formability, and the United States uses more high-strength aluminum alloys 6111 and 6022.

What Is Aluminum Flashing Roll

 Aluminum flashing coil is a kind of material with certain anti-corrosion function which is mainly used in some construction industries to ensure the thermal insulation of the building and some of its waterproofness to a certain extent.

There are many types of aluminium flashing like roof, wall, sill, channel, through wall, cap,etc. The introduction of aluminum flashing decreases water penetration at obstacles such as chimneys, vent pipes, walls,etc., thus making buildings more durable and reducing indoor mold problems.

It also belongs to aluminum trim coil. The surface of the material uses metal aluminum foil as the surface layer, so it has the characteristics of moisture resistance, air tightness, heat insulation, resistance to solar ultraviolet light, and abrasion resistance. The aluminum flashing roll is generally composed of three parts, namely self-adhesive layer, middle layer and waterproof surface layer.

Its thickness is about 1.5mm and the main raw materials are butyl rubber, polyester cloth, metal aluminum foil, etc. Among these raw materials, butyl rubber is mainly used for the self-adhesive layer, which can enhance the adhesion of the aluminum foil.

Since the area covered by the aluminum flashing roll is mostly uneven, so polyester fiberglass cloth is specially added in the middle of the aluminum coil, which can effectively ensure that the material is not easily deformed, and at the same time, it is resistant to high temperature and has a super waterproof function.

In addition, the use of aluminum foil as the surface of the aluminum flashing coil greatly increases the physical properties of the coil. It can be used safely between 80°C and -30°C without falling off. Moreover, the metal aluminum foil has high ductility, thin surface layer, strong sealing and corrosion resistance. At the same time, the ignition point of aluminum foil is high, so there is no need to worry about the fire problem.

The common specification of aluminum flashing is .019 aluminum coil, preferably .022 to .024-in. 24-inch aluminum flashing roll is also a popular choice. Welcome to leave message below to inquire what you need.

The Use of 6016 Aluminum in Car Making

 Aluminum alloy has the characteristics of light weight, wear resistance, corrosion resistance, high specific strength, good impact resistance, easy surface coloring, etc., and more than 80% of aluminum can be recycled, making aluminum alloy an ideal lightweight material for automobiles.

6xxx aluminum alloys can be heat treated and strengthened, which just matches the existing automobile body production system. It can go through solid solution and pre-aging in the aluminum sheet factory to make them have good formability, and then go to the automobile factory for stamping and forming to manufacture body components.

Then, the aging treatment can be realized directly by means of the baking paint coating and heating production line of the original steel automobile body components, and the obvious strength performance can be improved, so that the aluminum alloy body components have high concave resistance. Therefore, 6000 series aluminum alloys are considered to be the most promising aluminum alloy for car making.

6016 aluminum including 6016 t4 and 6016 t6 aluminum is widely used in ABS, but the heat treatment process is complicated, and pre-aging treatment T4P must be carried out between solution treatment and paint treatment to obtain good performance. Because it has good formability before stamping, and can rapidly increase the strength during the paint baking process after stamping, so it has high dent resistance.

The production process of 6016 aluminum alloy sheet in the aluminum plate factory is mainly as follows: proportioning, smelting, refining, adding grain refiner, casting, sawing, milling, homogenizing heat treatment, hot rolling, heat treatment, cold rolling, heat treatment (double grade aging) -stamping and bake hardening. 6016 t4 aluminum sheet often affects the final bake-hardening effect due to natural aging during transportation to automobile factories.

Compared with the steel plate front anti-collision beam assembly, the use of 6063 and 6016 aluminum alloys to manufacture the front anti-collision beam assembly not only greatly reduces the weight, but also improves the anti-collision effect. 6063 and 6016 alloys are two commonly used wrought aluminum alloys. The manufacturing cost of aluminum alloy crash beams is about 18.5% higher than that of steel beams.

 According to the material of the tank, it can be divided into steel tanker and aluminum tanker. Aluminum alloy tankers first appeared in the United States in the late 1920s. In the beginning, there were only aluminum alloy single tankers. In the 1940s, aluminum alloy semi-trailers appeared. In the 1960s, the tank shape of aluminum alloy tankers was more reasonable, and elliptical linear tanks began to appear. In the 1970s, due to the oil crisis and other reasons, aluminum alloy tankers received rapid development.

5182 aluminum is Al-Mg series anti-rust aluminum. The performance of 5182 aluminum plate is similar to that of 5A02, but because the magnesium content is slightly higher than that of 5A02, and a small amount of silicon is added, its weldability is better than that of 5A02.

5182 aluminum plate is one of the best-selling products on the market. It has a flat shape, good corrosion resistance, excellent cold processing performance, medium strength, high tensile strength and yield strength.

5182 aluminum sheet is a kind of aluminum alloy specially developed for road tankers for storing and transporting dangerous goods. It complies with the latest ADR (Agreement on the Transport of Dangerous Goods by Road) regulations. Using this material, the minimum thickness can reach 4mm when making a tank with a diameter of less than 1.8 meters; when making a tank with a diameter greater than 1.8 meters, the minimum thickness can reach 5mm, which has superior quality and safety performance. 5182 Aluminum is suitable for various welding methods, like TIG, MIG and EBW (electron beam welding).
