Tungsten Rods Characteristic Factors and Uses

As an important refractory metal, tungsten has the highest melting and boiling points of all metals and the lowest vapor pressure of all metals, which is why it is used in aerospace, electronics, chemical, nuclear, and other extreme environments. We will now take a look at the properties and use of Tungsten Rods. Here are some answers.

Tungsten Rods are characterized by specific property factors.

The range of applications of conventional sintered tungsten products is limited by their low density, low strength, and poor plasticity. The products prepared from tungsten alloys are classified as Tungsten Rods, Tungsten Squares, Tungsten Plates, and Tungsten Balls depending on the shape of the product. The main difference is in their use, but their physical and chemical properties are similar, with the same high melting point, high density, high hardness, high strength, low coefficient of thermal expansion, high modulus of elasticity, resistance to wear and tear, high temperature and good electrical and thermal conductivity. The specific properties of Tungsten Rods are, of course, related to the ratio of the raw material. Most of them are alloys with the refractory metal tungsten as the hard phase and cobalt, nickel, iron, copper, and other metals as the binding phase. When the binder is copper metal, Tungsten Rods will vary in color, melting point, density, and electrical conductivity: as the copper content increases, cutting tungsten carbide rod will tend towards a copper color and have better electrical conductivity; as the tungsten content increases, Tungsten Rods will have a higher melting point and density.

Information on the use of Tungsten Rods.

Tungsten alloys are sintered alloys containing high density and strength, which is 50% of the density of PM products and lead products. This gives the tungsten carbide rod a low coefficient of thermal expansion, good thermal conductivity, and good material properties. At high temperatures, tungsten alloys act as a material with a high melting point and a low coefficient of thermal expansion. The addition of tungsten alloy elements improves machinability, toughness, and welding. With no heat treatment, low erosion and excellent heat resistance cracking dies are simple to manufacture and it has found widespread use in die casting.

Tungsten Rods are mainly used as a component in forging materials, tools and cartridges, light bulb tungsten wires, electrical contact points, heat conductors, crankshaft and cylinder tungsten wire barrels, and various components of heat resistant steels. Doped Tungsten Rods are used in the production of filaments for lamps or electron tube filaments, which are guaranteed to have significant resistance to high temperatures. Pure tungsten is a naturally occurring metal mined from the ground. In its raw form, pure tungsten is very brittle.
