Tungsten Square
Supply state:sintered state；crash test:50%deformation without cracking.Tungsten alloy square block has high hardness,high density,high melting point,good elastic modulus,non-toxic,no pollution and high temperature resistance attributes,which is widely used in the field of equipment.
Tungsten heavy alloy product density is up to 18.6g/cm3(＞2 times higher than steel density),normally the hardness is up to 35 HRC,its’good corrosion resistance,high temperature resistance,small size,wear resistance,impact resistance and durability,high tensile strength,high extensibility,good machining,non-toxic and no pollution and other excellent characteristics,which make it to be the best material for counterweight.
The tungsten alloy products are in accordance with the AMS-T-21014/AMS 7725E(MIL-T-21014)/ASTM B 777-19 standards.
