GB TU1 with high purity oxygen-free copper corrosion-resistant tinned copper belt elemental copper is copper, so named because of its color is purple. See the various properties of copper. Copper is an industrial copper, its melting point is 1083 ℃, no allotrope transition, the relative density of 8.9, five times as magnesium. The quality of the same volume ratio of about 15% by weight of ordinary steel. Because of its red roses after the oxide film formed on the surface purple, it is generally known as copper. It is a copper-containing some oxygen, which is also called an oxygen-containing copper. GB copper T2 (Japanese standard copper C1100): Also known as copper, copper purity ≥99.9%. Outstanding thermoelectric conductivity, workability, ductility, corrosion resistance and weather resistance. Can be applied to the printed circuit board, covered with copper wires, terminals, electrical appliances, distillation, construction and chemical industries. GB copper belt TU2 (Japanese standard copper belt C1011): Also known as oxygen-free copper purity to reach 99.95% purity, oxygen content of not more than 0.003%, the total content of impurities is not more than 0.05%. No hydrogen embrittlement appearance, high conductivity, processing capabilities and welding capabilities, functionality and low temperature corrosion features are good. Applies to terminals, heat sink, transformer coils, high conductivity materials. [Mobile: 13725715788] [Tel: 0769-85317866】 【QQ: 1397644622] GB copper TP1 (Japanese standard copper C1201), the national standard copper TP2 (Japanese standard copper C1220): Also known as phosphorus deoxidized copper, the copper content of more than ≥99.9%. Ductility, extrusion workability, weldability, corrosion resistance, weather resistance, thermal conductivity, electrical conductivity was good, particularly for welding. Suitable for bathing water heaters, liners, handicrafts, construction with materials, chemical industry, electrical terminals copper alloy copper calculated weight (kg) = 0.0089 × thickness × width × length brass Weight (kg) = 0.028 × wall thickness × (OD - Wall Thickness) × length of copper Weight (kg) = 0.00698x diameter x diameter x length rods Specifications: Ф1.0mm ~ 350.0mm; sheet size: 0.3mm ~ 160mm Pipe Specifications: Ф0.5mm ~ 800mm belt Material Specifications: 0.03mm1 ~ 1.5mm wire Specifications: Ф0.03mm ~ 12mm copper (copper) coil specifications: 19 * 1,18 * 1,16 * 1,14 * 1,12 * 1,10 * 1,8 * 1,6 * 1,4 * 1 and other hexagonal rod specifications: S 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 13mm, 14mm, 17mm, 19mm, 22mm, 24mm, 27mm, 30mm, 32mm, 36mm, 41mm, 46mm, 50mm, 55mm and other side bar Specifications: 4 * 4mm-50 * 50mm flat wire specifications: 0.5 * 5mm-18 * 22mm copper use is much more widespread than iron, 50% of the copper electrolysis purification of copper per year for the electrical industry. Copper are talking about here, really want to be very pure, more than 99.95% copper job, a very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Mainly used for thermal flat plate collectors and other equipment produced generators, bus, cable, switch gear, transformers and other electrical equipment and heat exchangers, piping, solar heating device. Copper oxygenated (oxygen readily when mixed with a small amount of copper) a great influence on the electrical conductivity of copper is generally used in the electrical industry must be oxygen-free copper
