So - called copper row, in fact, we usually said that the pure copper. Due to its appearance color appears to be purplish red, so named copper. Its various properties may be referred to copper. In fact, the red copper row belongs to industrial pure copper, with a melting point of 1083℃, no isomorphic transformation and a relative density of 8.9. It is about 15% heavier by volume than ordinary steel.
Can show rose red, basically be because the surface of this kind of red copper row had oxidized reaction, formed a purple after oxidizing film, reason calls red copper commonly. It is the copper that contains certain oxygen, call to contain oxygen copper accordingly. So how does it work? In general, it has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy to fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking, in addition to cheap, is a widely used variety of common copper.
The characteristics and application scope of red copper bar are described as follows:
Firstly, it is about the mechanical properties of red copper row. Its tensile strength is above 315 and its elongation is not less than 30.
Sample size: diameter >2.0 ~ 4.0. The heat treatment specification for this product requires: heat processing temperature 650 ~ 850℃; Annealing temperature 600 ~ 700℃; Low temperature annealing temperature 270 ~ 300℃ to eliminate internal stress.
Analysis of performance advantages of red copper bar:
At present, in different applications, the types of alloy elements contained in the copper bar are not the same, so it can be divided into ordinary type and special type. The red copper row by its organization has alpha and (alpha + beta) two kinds. Among them, the former can only be subjected to cold deformation or hot extrusion because of lead's harmful effect and low plasticity at high temperature. A + beta copper row has good plasticity at high temperature and can be forged.
In general, the performance advantages of red copper row can be summarized as follows: 1. 2, no magnetic, high conductivity, impact without spark and other characteristics; 3. Good fluidity and the ability to reproduce fine patterns. Because of its superior performance, red copper row has been widely used in the manufacturing industry.
