Tungsten Nickel Iron
We are a professional supplier of tungsten nickel iron alloys. We own excellent facilities including hot rolling mills and four-high cold rolling mills. The content of tungsten in tungsten nickel iron alloy is more than 85%. The tungsten-nickel-iron alloy also contains a small amount of other elements include nickel, copper, cobalt, molybdenum, chromium, etc. Due to the different material properties and alloy applications, Tungsten alloys can be divided into the following types with different compositions: W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, etc. Our tungsten nickel iron alloy conforms to ASTM B777 standard.
Tungsten Nickel Iron
Tungsten nickel iron alloy belongs to non-magnetic metals. Its tensile strength is between 700 and 1000 MPa. The thermal conductivity of tungsten nickel iron alloy is five times that of steel. Its ability to absorb radiation is 30% to 40% higher than that of lead. The coefficient of thermal expansion of W-Ni-Fe alloy is 1 / 3 or 1 / 2 times of that of iron or steel.Tungsten nickel iron alloy is widely used in aviation industry and aircraft manufacturing industry. It is also used in electronic equipment, medical and industrial field. Tungsten nickel iron can also be used to make knife tools.
