Tungsten alloy products description
High specific gravity tungsten alloy products are a special material made from a mixture of tungsten and other alloying elements with extremely high density and hardness. This material is commonly used in the manufacture of wear-resistant components and cutting tools because of its ability to maintain its hardness and strength under extreme temperatures and pressures.
Tungsten-nickel-iron alloy applications
Used as shielding components
Electrical products with rivet heads and switching contacts
gyroscope rotors, vibration dampers in aerospace applications
Counterweights, rivet heads, balancing weights Radiation shielding devices
Die casting moulds, tool holders, boring bars, automatic watch hammers in the field of mechanical devices.
