Hardness HRC35 Tungsten Alloy WNiCu Parts For Radiation Shielding Material
Introduction of Tungsten Heavy Alloy
Tungsten based heavy alloy is a kind of alloy based on tungsten (tungsten content is usually
79% ~ 97%), composed of a small amount of Ni, Fe, Cu, Co, Mo, Cr and other elements, also known as high-density tungsten alloy or heavy alloy. It is generally produced by powder metallurgy process, and the common materials are tungsten nickel iron alloy and tungsten nickel copper alloy.
1. Dimension: According to customers' requirements
2. Density: 15.2-19.0 g/cm3
3. Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu
4. Surface: Vacuum annealed or un-annealed
5. Shape: plate, bar, customized parts
Tungsten based heavy alloy has the advantages of high density, high strength, low expansion coefficient, good high temperature oxidation resistance, good machining performance, wear resistance and strong ray absorption ability. Based on these excellent functions, it is widely used in aerospace, aviation, military, oil drilling, electrical instruments, medicine and other industries. It mainly includes:
1. Tungsten alloy benchmark, fishing pendant series of tungsten alloy darts
Tungsten bead and tungsten ball series
2. Balance weight series: balance weight for machinery; Flying hammer; Oil drilling counterweight rod; Golf counterweight; Racing car counterweight; Mobile phone and game console vibrator; Gyroscope rotors for aviation and spacecraft; Clock pendulum; Balance weight ball; Shockproof cutter bar.
