The high specific gravity tungsten alloy is vividly called 3 high (or 3H) alloy, namely: high density, high strength, high hardness alloy, so an important use of high specific gravity alloy is widely used for counterweight parts.
The high proportion tungsten alloy counterweight produced from clean metal is pollution-free and in line with international environmental standards. It has a large ratio (>18g/cm3), small size, strong wind resistance, light entry into water, fast sinking, is the best alternative lead weight products, popular in Europe and The United States and other developed countries.
Tungsten alloy counterweight is widely used in: guns, cars, machinery with balance hammer, flying hammer; Weighting rod used in oil and other drilling industries; Clock pendulum; Vibrators used for mobile phones and game machines, such as shockproof knife rod and counterweight ball; Ballast counterweight blocks, counterweight components, etc., for navigation and sailing vessels; Gyroscopes used in aerospace, aircraft counterweights, etc.
