Tungsten rod shipment record, September 1st

Tungsten rod is an important metal material known for its high melting point, high thermal conductivity, high temperature, and high strength. Tungsten rods are usually made of tungsten alloy, which is made by using special high-temperature powder metallurgy technology to give tungsten alloy rods low thermal expansion coefficient, good thermal conductivity, and excellent material properties. The addition of tungsten alloy elements improves the machinability, toughness, and weldability of the material, solving problems related to heat treatment of other tool materials.

Industrial applications: Tungsten rods play an important role in the industrial field, with their high melting point and low thermal expansion coefficient making them an ideal material for high-temperature environments. For example, tungsten tubes are key components of quartz continuous melting furnaces, as well as crucibles and accessories used for ruby and sapphire crystal growth and rare earth melting in the LED industry.

The physical properties of tungsten rods include high purity (generally above 99.95% purity), high density (generally above 18.2g/cm ³), recommended operating temperature below 2500 ℃, and specific thermal expansion coefficient and specific heat capacity. These characteristics make tungsten rods perform well in applications that require high temperature and high strength loads.
In addition, the manufacturing process of tungsten rods includes extracting tungsten from tungsten ore and then making alloy rods through powder metallurgy technology. Pure tungsten rods have a higher melting point (3422 ° C) and a series of excellent physical properties, such as low coefficient of thermal expansion and good thermal conductivity, which enable them to maintain good performance under various extreme conditions.
