Why do copper soft connections choose copper bars? Because of its good electrical conductivity. Copper soft connection raw materials are usually copper bars, copper bars because of its appearance color looks purple, so it is named copper, that is, pure copper.
Processing properties of copper bar
The first is about the mechanical properties of the copper bar, its tensile strength is more than 315, and the elongation is not less than 30.
Sample size: Diameter > 2.0~4.0. The heat treatment specifications used by the product are: thermal processing temperature 650 ~ 850°C; Annealing temperature 600 ~ 700°C; Low temperature annealing temperature 270 ~300°C to eliminate internal stress.
The performance advantages of copper bars can be summarized as follows :
1, with good wear resistance, low temperature resistance;
2, non-magnetic, high electrical conductivity, impact without sparks and other characteristics;
3. It also has good fluidity and the ability to reproduce fine patterns. Because the copper bar has so many superior properties, it has been widely used in the manufacturing industry.
Analysis of performance advantages of copper bar :
At present, in different applications, the types of alloying elements contained in the copper row are not the same, so it can be divided into ordinary type and special type. Copper row according to its organization has a and (a+β) two kinds. Among them, the former can only be cold deformation or hot extrusion because of the harmful effect of lead and low high temperature plasticity. (a+β) copper row has good plasticity at high temperature and can be forged.
