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.
