JinLei purple (red) copper properties: copper, also known as copper has good electrical conductivity and thermal conductivity, excellent plasticity, ductility and good corrosion resistance, easy to hot and cold pressure processing. It can be used extensively for the manufacture of wires, cables, brushes, EDM dedicated electric conductivity of copper corrosion and other requirements of a good product. JinLei purple (red) copper properties: high purity, fine organization, the oxygen content is very low. Nonporous, trachoma, excellent loose, conductivity, electrical erosion of high accuracy out of the mold surface, the heat treatment process, the electrode had no direction, suitable for playing fine, fine playing, good thermal channel of processing, scalability, corrosion resistance and weather resistance. JinLei purple (red) copper use can be used in electrical appliances, steam leavened construction and chemical industries, in particular electrical terminal printed circuit boards, copper wire and masking, air, bus terminals. Electromagnetic switch, pen, house root panels. JinLei purple (red) copper characteristic copper (copper) Copper is a rose red metal, copper oxide film formed on the surface after the purple, often called copper or copper, density 8.96g / cm, specific gravity 8.89g / mm, thermally coefficient 386.4w / (mk) resistivity (20 ℃ pm) of 0.018Ω · mm2 / m, divided according to the hardness hardness value ≥85.2HV o state, 1/4 hard, 1/2 semi-hard, full hard, special hard, elastic hard, super-elastic. The difference between the appearance of copper and brass in different colors, brass copper than soft, small rebound after bending should be reinstated; brass after hard bent back as it is basically a large rebound. The difference between oxygen-free copper and copper: the copper oxide layer, oxygen-free copper oxide does not, different chemical composition. T2 copper plate presentation purposes copper is pure copper, having a rose named after the red, copper content ≥99.90, its melting point is 1083 ℃, thermal processing temperature 900 ~ 1050 ℃; annealing temperature of 500 ~ 700 ℃, not with Su heterogeneous transition, the relative density of 8.9, about 15% heavier than ordinary steel, magnesium five times. After the oxide film formed on the surface was purple, it is generally referred to as copper, which is containing oxygen copper, which is also called an oxygen-containing copper, 50% of the annual copper is electrolytic purification of copper, since copper has good electrical conductivity, thermal conductivity resistance, plasticity, corrosion resistance and can welding and brazing are often widely used in the electrical industry.
