Tungsten alloy strip is small in volume, and very dense, which means it can be used in all the applications requiring small but heavy parts, such as counterweights for racing cars, boats, yachts, sailboats, airplanes, helicopters, tanks, etc. The most popular application for tungsten alloy strips is radiation shielding in the form of radiation shielding walls, shielding for X-ray tubes, tungsten vial shielding, etc. Tungsten alloys usually consist of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloys also contain Co, Mo, Cr, etc. These applications all utilize its superior radiation adsorption capability. After precision machining, tungsten alloy strips possess wear resistance and anti-corrosive ability.
