Copper coil refers to the rolled sheet of copper, which includes hot rolling and cold rolling. Copper strip is a rolled copper product with a thickness of 0.06 to 1.5mm. Copper strip can be copper strip is actually a general term for copper plate and copper strip.
The thickness of the red copper strip can reach 50mm. Its mechanical property is tensile strength: ≥ 315; Elongation: ≥ 30 (Note: tensile mechanical properties at room temperature of other types of plate strips except those for lock making and clock making); Sample size: diameter > 2.0 ~ 4.0; Heat treatment specification: hot working temperature 650 ~ 850 ℃; Annealing temperature 600 ~ 700 ℃; The low-temperature annealing temperature for eliminating internal stress is 270 ~ 300 ℃.
Red copper plates and strips have good mechanical properties, good plasticity in hot state, fair plasticity in cold state, good machinability, easy fiber welding and welding, corrosion resistance, but easy to produce corrosion cracking. In addition, they are cheap and widely used as a common red copper variety.
