Tungsten sphere is widely used in water meter, flow meter, pen making and other fields.
WNiFe density 17.5 18.5 high specific gravity spheroidal tungsten nickel-iron alloy Tungsten alloy Tungsten ball
Compared with lead, tungsten alloy ball is non-toxic, pollution-free and safer. The high density of tungsten alloy allows the tungsten alloy sphere to maintain its shape even under extreme conditions. Depleted uranium is similar in density to tungsten alloys, but it is radioactive and radioactive materials require special permits, making its use difficult and costly.

Physical properties
The chemical formula is WC. The full name is Wolfram Carbide, which is a black hexagonal crystal with metallic luster and similar hardness to diamond. It is a good conductor of electricity and heat. Melting point 2870ºC, boiling point 6000ºC, relative density 15.63(18ºC).
Chemical properties
Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and easily soluble in nitric acid-hydrofluoric acid mixture. Pure tungsten carbide fragile, if a small amount of titanium, cobalt and other metals, can reduce the brittleness. Tungsten carbide used as a steel cutting tool is often added to titanium carbide, tantalum carbide or a mixture of them to improve knock resistance. Tungsten carbide is chemically stable. In tungsten carbide, carbon atoms are inserted into the gaps of the tungsten metal lattice without destroying the original metal lattice, forming interstitial solid solutions, so it is also called interstitial (or interstitial) compounds.
Edit by preparation
Tungsten carbide can be prepared by heating a mixture of tungsten and carbon at high temperatures. The presence of hydrogen or hydrocarbons accelerates the reaction. If tungsten containing oxygen is used for preparation, the product must eventually be vacuum treated at 1500ºC to remove the carbon and oxygen compounds.

Tungsten carbide is suitable for mechanical processing at high temperatures, and can be used to make cutting tools, structural materials for kilns, jet engines, gas turbines, nozzles, etc. Another compound of tungsten and carbon is ditungsten carbide, chemical formula W2C, melting point 2860ºC, boiling point 6000ºC, relative density 17.15. Its properties, manufacturing method, use with tungsten carbide tungsten steel, also known as hard alloy, its hardness is second only to diamond, its chemical properties are stable, even in the case of heating, it does not work with hydrochloric acid, sulfuric acid, even in aqua aqua will not be dissolved. Tungsten is extremely resistant to high temperature, known as the most dissoluble metal in nature, with a melting point of up to 3410ºC; Hardness in the metal is also among the best, only heating to a very high temperature, can be processed by pressure. Tungsten steel ball is widely used in water meter, flow meter, pen and other fields!
