TUNGSTEN COPPER FLAT BAR, 7 mm

The Copper Tungsten R07004 Hollow Bar is used to reduce the weight of the product in relation to the length and diameter. There are different types and forms to the tungsten copper rods such as the Tungsten Square Bar. The material is sometimes used for its primary purpose where are secondary need for strength arises.What are the uses of tungsten copper electrodes?Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material, the composite is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining. omposites Nominal Composition(% Weight) Density(g/cm3, ≥) Electrical Resistivity(20°C, µΩ·cm, ≤) Electrical conductivity(IACS%, ≥) Hardness(≥)Brinell Hardness Bending Strength Mpa Kgf/mm2 Mpa Kgf/mm2 CuW50 50% Copper50% Tungsten 11.85 3.2 54 1128 115 --- --- CuW55 45% Copper55% Tungsten 12.3 3.5 49 1226 125 --- --- CuW60 40% Copper60% Tungsten 12.75 3.7 47 1373 140 --- --- CuW65 35% Copper65% Tungsten 13.3 3.9 44 1520 155 --- --- CuW70 30% Copper70% Tungsten 13.8 4.1 42 1716 175 667 68 CuW75 25% Copper75% Tungsten 14.5 4.5 38 1912 195 706 72 CuW80 20% Copper80% Tungsten 15.15 5.0 34 2158 220 736 75 CuW85 15% Copper85% Tungsten 15.9 5.7 30 2354 240 765 78 CuW90 10% Copper90% Tungsten 16.75 6.5 27 2550 260 804 82
