What Substance Does Red Copper Belong To

Red copper red copper is red copper

Pure copper, also known as red copper, has good electrical and thermal conductivity, excellent plasticity, easy to hot and cold pressure processing, a large number of used in the manufacture of wire, cable, brush, EDM special electrocorroded copper and other products requiring good electrical conductivity. That is red copper. Pure copper from the smelting of sulfide or oxide copper ores can be used for casting and making utensils. Ming Song Yingxing "Tiangong open material · copper" : "Where copper for the world, out of the mountain and oven, there is red copper. Take calamine or bonobo ginseng and change the color to brass; Copper was refined from arsenic and other drugs; Smelting of alum, nitrate and other drugs into bronze; Guang tin ginseng and ring copper; Bonobo lead and write [diarrhea] for cast copper. The primary quality is just red copper." Guo Moruo, The second section of the third chapter of the First Volume of Chinese History: "The red copper they smelted was pure except for the trace amount of natural copper (0.1 red copper street signs

-0.2%), no tin or lead was added artificially to alloy. Although the hardness of red copper is poor, it can be made into various tools and ornaments directly after being beaten." Characteristics: High purity, fine tissue, very low oxygen content. No pores, trachoma, loose, excellent electrical conductivity, high precision of the surface of the electrocorroded mold, after heat treatment process, the electrode is non-directional, suitable for fine punching, fine punching, with good thermoelectric channel, processing, ductility, corrosion resistance and weather resistance. Application: It can be used in electric appliance, steam slip construction and chemical industry, especially in terminal printing electrical circuit board, copper tape for wire masking, air cushion, junction bar terminal. Electromagnetic switch, pen holder, house root board, etc. Copper density: 8.96g/(cm) copper specific gravity: 8.89g/(mm) Cu≥ 99.95% O<003 conductivity ≥57ms/m copper vessels
