Aluminum wire actually belongs to aluminum and magnesium alloy metal, as alloy elements with magnesium as the main material, it has good forming performance, good corrosion resistance, high cold workability, and has moderate strength, is used in the manufacture of aircraft fuel tank, oil pipe and traffic vehicles, ships of sheet metal parts, instruments, street lamp studs, hardware products and electrical shell.
As a kind of widely used anti-rust aluminum, the strength of aluminum wire is very high, especially with fatigue strength, high shape, can not be strengthened by heat treatment, in the semi-cold hardening, good shape, cold hardening when the shape is low, this alloy weldability is good, machinable bright, can be polished, is mainly used for high plasticity and good weldability. Low-load parts that work in liquid or gaseous media, such as fuel tanks, gasoline or lubricating oil conduits, various liquid containers, and other low-load parts made by deep drawing.
The heat treatment process of aluminum wire is uniform annealing heating 440 degrees Celsius, heat preservation for 12 to 14 hours, air cooling; Rapid annealing heating 350 to 410 degrees Celsius, holding time is 30 to 120min, air or water cooling; High temperature annealing heating 350 to 420 degrees Celsius, the thickness of the finished product is greater than or equal to 6mm or 4mm, low temperature annealing heating 250 to 300 degrees Celsius or 150 to 180 degrees Celsius, holding time for 1 to 2 hours, air cooling.
In particular, it is worth mentioning that most of the aluminum wire is produced by the international advanced cladding welding process. The copper layer is made of high density, good electrical conductivity and high purity copper, and the metallurgical combination between the aluminum core wire is achieved, and the copper layer is evenly distributed along the circumferential direction and longitudinal direction, and the concentricity is good.
