Anodizing

Including nickel plating, silver plating, gold plating, zinc plating, copper plating, chrome plating, etc., can be covered with a layer of other metals on the surface of aluminum.

The polishing treatment of aluminum as the anode in the appropriate electrolyte can further improve the finish of the aluminum surface.

The T6 state is obtained by heat treatment through two steps of solution and artificial aging, which makes it have high strength and hardness, but relatively low toughness. The T651 state is a heat treatment through two steps of solid solution and natural aging, which not only maintains a high strength and hardness, but also makes its toughness relatively high.

Due to the differences in the physical properties of these two states of aluminum alloy materials, their application fields are also different. Due to its high strength and hardness, 6061 aluminum alloy in the T6 state is commonly used to manufacture parts that need to withstand high impact and vibration, such as automobile wheels. The T651 6061 aluminum alloy, because of its high strength and high toughness, is more suitable for occasions that need to withstand high pressure and impact, such as mold manufacturing.

From the treatment process point of view, 7075-T6 is the aluminum alloy state obtained by solid solution treatment and artificial aging treatment. This treatment can significantly improve the strength and hardness of 7075 alloy, while maintaining good machinability and toughness. The 7075-T651 state is on the basis of the T6 state, the stress relief treatment is carried out, that is, the residual stress after the solution treatment is eliminated and the tensile treatment is carried out.

From the point of view of material characteristics, 7075 aluminum alloy is known for its excellent strength and hardness, and is widely used in the aerospace industry, automobile manufacturing and high-strength structures. The 7075-T651 state may exhibit higher stability and reliability in some applications due to its elimination of residual stress. But it is worth noting that although 7075 alloy corrosion resistance is relatively good, but compared to some other aluminum alloys, such as 6063, its corrosion resistance may be slightly worse.

From the application field, 7075-T6 and 7075-T651 are favored for their high strength and hardness. They are often used in the manufacture of aircraft structural parts, aircraft landing gear, ship structures, high-speed train structures, automobile bodies and wheels, offshore oil well platforms, large molds and so on. The specific choice of which state of aluminum alloy needs to be determined according to the needs of practical applications and working environment.

In terms of treatment process, 7075-T7351 aluminum alloy needs to go through two main steps of solution treatment and aging treatment to obtain its specific mechanical and chemical properties.
