Tungsten Alloys for Gamma-Ray Shielding Material

0 Comment

Tungsten Alloys for Gamma-Ray Shielding Material In addition to tungsten-nickel-iron alloy (W-Ni-Fe alloy), γ-ray shielding material can also be produced with tungsten copper alloy (W-Cu alloy). W-Ni-Fe alloy and W-Cu alloy are both high-density tungsten alloys, both of which use the W phase as the hard phase, but due to the difference in bonding phase metals, their production processes and […]
