7075 7020 7005 extra super duralumin aluminum coil strip supplier

Product Description

Characteristics of 7075 aluminum:

7075 refers to a commonly used alloy among 7 series aluminum alloys. The most common aluminum alloy with the best strength is 7075 alloy. It is commonly used in CNC cutting and manufacturing parts, and is suitable for flying machine frames and high-strength parts. The 7 series aluminum alloy contains zinc and magnesium elements. Zinc is the main alloy element in this series, so the corrosion resistance is quite good. Adding a little magnesium alloy can make the material reach a very high strength after heat treatment.

The 7 series aluminum alloy belongs to Al-Zn-Mg-Cu series super-hard aluminum, which is an ultra-high-strength deformed aluminum alloy that has been widely used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. Its characteristics are: good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; tendency to stress corrosion cracking; need to be covered with aluminum or other Protective use. Two-stage aging can improve the alloy's resistance to stress corrosion cracking.

Surface treatment method of aluminum

Anodizing: An aluminum material is used as an anode and placed in an electrolyte solution. The use of the electrolyte to form a dense oxide film on the surface of an aluminum profile is called anodization.

Electrophoretic coating: Dissolve the electrophoretic coating in water to cause electrolysis to generate charged particles. Under the action of an external electric field, the charged particles move to the opposite pole and deposit on the surface of the aluminum profile. The formation of a dense and uniform film layer is called electrophoresis Painting.

Powder coating: The powder coating is placed in a spray gun, and under the action of compressed air, the powder particles are adsorbed on the surface of the aluminum profile by high voltage static electricity. This is called electrostatic powder spraying.
