provide High Density Tungsten Heavy Alloy Plates / Bars Thickness 0.1mm to 120mm WNiCu Density of tungsten heavy alloy plates usually ranges from 17.0g/cm3 to 18.8g/cm3, which is the twice of steel, more than 1.5 times of lead. It has low thermal expansion coefficient, high strength and high modulus of elasticity. Tungsten heavy alloy has low thermal coefficient but it has high absorption ability and high-energy rays. The tungsten heavy alloy we make conforms to ASTM B777-99 standard. Tungsten heavy alloy plates are widely supplied for balancing molds and high temperature molds. Also it can be made into protective shields and high energy rays. Tungsten heavy alloy plates play an important role in aircraft controlling surfaces, helicopter rotor systems, parts of engine and shipping ballast.
