Chromium zirconium bronze one, has good electrical conductivity, thermal conductivity, high hardness, wear resistance and explosion resistance, crack resistance and high softening temperature, welding electrode loss is less, welding [SCALE STEEL]speed is fast, the total welding cost is low, suitable for welding welding machine electrode related pipe fittings, but the electroplating workpiece performance is general.
Chromium-zirconium copper is a kind of wear-resistant copper, especially good hardness, excellent conductivity and good tempering resistance, good upright, thin sheet is not easy to bend, is a good material processing electrode. Density 8.95g/cm3 conductivity 43MS/m softening temperature 550℃, generally used for making working [SCALE STEEL]temperature below 350℃ welding machine electrode. Motor rectifiers and other kinds of high temperature operation \ require high strength. Hardness. Electrical conductivity and conductive parts, and may also be used in bimetallic form for brake discs and discs.
Its main brands are; CuCrlZr, ASTM C18150 C18200 c18500
Application: This product is widely used in automobile, motorcycle, barrel (tank) and other machinery manufacturing industry welding, conductive [SCALE STEEL]nozzle, switch contact, mold block, welding machine auxiliary devices for various materials.
