Tungsten Powder Molding Sintering

Tungsten powder powdered metal tungsten is a raw material for preparing tungsten processed materials, tungsten alloys and tungsten products.

Tungsten alloys are alloys based on tungsten with other elements added. In metal, tungsten has the highest melting point, high temperature strength and creep resistance and thermal conductivity, conductive and electron emission performance are good, than major, in addition to a large number of used in the manufacture of cemented carbide and for alloy additive, tungsten and its alloys are widely used in electronics, electric light source industry, also in the aerospace, casting, weapons, etc. Used in rocket nozzle, die-casting molds, armor-piercing core and contact, such as heating element and heat shield, etc.

Tungsten alloy sintered products can be controlled by precise parameters to obtain tungsten alloy products with excellent properties.

Vacuum sintering is the conversion of a powdery material into a dense body, which is a traditional process. This process has long been used to produce refractory materials and ultra-high temperature materials for tungsten alloy products. Generally, after the tungsten powder is molded, the dense body obtained by sintering is a polycrystalline material, and its microstructure is composed of crystals, etc. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure. The properties of inorganic materials are not only related to the material composition (chemical composition and mineral composition), but also closely related to the microstructure of the material.

The advantages of tungsten alloy products mainly focus on its physical properties. Due to the high density of tungsten alloy, it is widely used in the field of tungsten alloy shielding parts and tungsten alloy weight balancing. Tungsten alloy shielding parts can shield radioactive particles by high density, which plays an important role in radioactive medical and industrial fields. Tungsten alloy has advantages in physical size and weight ratio compared with other metal materials due to its high density. Tungsten alloy weight according to different USES, there are great differences in the shape, such as square block, round bar, round ball are common shape. Tungsten alloy can be used for weighing materials of automobiles, ships, submarines, aircraft and sports equipment.
