Processing characteristics of aluminum alloy parts

Aluminum alloy parts processing is the most widely used anti-rust aluminum. Its strength is not high, it cannot be strengthened by heat treatment, it has high plasticity in the annealed state, and has good corrosion resistance, good weldability and poor machinability. It is used to manufacture low-load parts that require high plasticity and good weldability and work in liquid or gaseous media, such as fuel tanks, oil pipes, liquid containers, etc.; wire rods can be used to make rivets. High corrosion resistance and good welding performance. Thermal conductivity and electrical conductivity are much lower than pure aluminum. It can be strengthened by cold deformation and cannot be strengthened by heat treatment. Suitable for welding structural parts. The magnesium content of aluminum-magnesium rust-proof aluminum is slightly higher than the strength, the heat treatment cannot be strengthened, the annealing state has high plasticity, the semi-cold hardening plasticity is medium, and the welding performance is still good. Containers and other parts. It has high strength and corrosion resistance, good plasticity in the annealed and extruded state, and the air tightness and plasticity of the weld by argon arc welding are acceptable. Good machinability. For welding containers, stressed parts, aircraft skins and skeleton parts.
