What is hard heavy alloy WC?
hard heavy alloy Tungsten metal is a grayish-white lustrous metal that is often brittle and hard to work. Of all metals in pure form, tungsten has highest melting point of all elements except carbon - vary between 3387°C and 3422°C. It also has good thermal and electrical conductivity. Its electrical conductivity at 0°C is about 28% of that of silver which itself has the highest conductivity of all metals. In addition, it has low vapor pressure at high temperatures.
Such properties make tungsten metal a high performance material in high temperature products and processes. Tungsten metal powder is used as a filler material in plastic composites, which are used as a nontoxic substitute for lead in bullets, shot, and radiation shields. Since this element's thermal expansion is similar to borosilicate glass, it is used for making glass-to-metal seals.
Applications of Tungsten crucibles
Tungsten crucibles and other parts can be used for sapphire crystal growth and rare-earth melting with its high temperature resistance, low pollution and other excellent characteristics. we supplies all kinds of tungsten crucibles and the whole set of tungsten parts used in hot zone of the sapphire grower according to customer's drawings and specific requirements.
