Tungsten alloy is a non-toxic and environmentally-friendly alloy material. As a new radiation shielding material, tungsten alloy has a better shielding effect than the traditional radiation shielding material heavy metal lead. Research shows that for gamma rays of the same energy, the shielding effect of the new radiation shielding material tungsten alloy is far better than that of lead, which provides a reference for choosing tungsten alloy as a shielding material in special occasions, and provides a new choice in…

Non-toxic and environmentally-friendly tungsten heavy alloy is an ideal anti-radiation material for applying in the field of medical shielding. Tungsten heavy alloy is a ternary alloy composed of 90-98% W and a small amount of Ni, Fe or Cu. There are mainly two series of tungsten heavy alloys including W-Ni-Fe alloy and W-Ni-Cu alloy.
