Copper Wire Scrap 99.99%

In life, practical copper wire as a conductor. Good conductivity, a large number of used in the manufacture of wires, cables, brushes, etc.; Good thermal conductivity, commonly used to manufacture magnetic instruments, instruments, such as compass, aviation instruments, etc., to prevent magnetic interference; Excellent plasticity, easy to hot pressing and cold pressing processing, can be made into tubes, rods, lines, strips, belts, plates, foil and other Copper materials. Pure copper products have smelting products and processed products two kinds.

It has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion rupture, in addition to cheap price, is widely used as a common Brass variety.Mechanical properties, tensile strength: ≥315, elongation: ≥30

Note:

tensile mechanical properties of other wires at room temperature except those used for making locks and clocks Sample size: diameter > 2.0 ~ 4.0, heat treatment standard, hot working temperature 650 ~ 850ºC, annealing temperature 600 ~700ºC Low temperature annealing temperature to eliminate internal stress 270 ~ 300ºC
