High specific gravity tungsten alloy material is a kind of alloy with tungsten as the matrix (W content 85-99%) and added with elements such as Ni, Cu, Co, Mo, Cr. According to alloy composition characteristics and uses, it can be divided into main series such as W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, and its density is between 16.5-19.0g/cm3 Adjustable. Generally, large and special-shaped parts are produced by isostatic pressing technology, small products are produced by mould pressing, extrusion and injection moulding technology, and bars and sheets are produced and processed by forging and rolling.
Specification: -200 mesh
Purity: 4N-6N
Uses: Used to prepare high-purity tungsten targets and high-purity tungsten alloy targets, to prepare cemented carbide tools, powder metallurgy, diamond tools, high-density alloys, contacts, refractory alloys. Tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy, etc.
Tungsten wire is made of pure tungsten powder sintered into strips by powder metallurgy, and then drawn. Tungsten aluminum wire commonly used for high temperature and shockproof filament, double helix filament, grid cathode, folded filament, tungsten twisted wire and other parts; plating a layer of gold on the surface of the tungsten wire can increase the corrosion resistance and oxidation resistance of the tungsten wire , Often used as electrode wire of copiers, corrosive electron emission materials, high temperature physics and meteorological instrument materials, etc.
Uses: Manufacturing electric light sources and electric vacuum parts, used as high-temperature heating elements and high-temperature structural parts, and used to make tungsten spirals for vacuum evaporation.
Because tungsten has a melting point of 3410°C, high purity, high density, no internal cracks, precise dimensions, and smooth inner and outer walls, it is widely used in sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces and other industrial furnaces The working temperature environment of the core container inside is generally above 2200℃. The tungsten crucible plays a key role in the success rate of seeding, the quality control of crystal pulling, the potting and the service life of sapphire crystal growth.
Application: Mainly used in metallurgical industry, mechanical processing, glass and ceramic industry and other fields
