Tungsten rod, also known as tungsten alloy rod. Tungsten alloy rods and Anviloy 1150 are made by refining metal powders at specific high temperatures using special high-temperature powder metallurgy techniques. This tungsten alloy rod material has a low coefficient of thermal expansion, good thermal conductivity, and good material properties.
At high temperatures, tungsten alloy rods serve as materials with high melting points and low thermal expansion coefficients. The addition of tungsten alloy elements improves workability, toughness, and welding. The performance of materials is based on the elimination of heat treatment related issues with other tool materials in the manufacturing industry of tungsten alloy rods.
Tungsten rods have special properties, such as low thermal expansion and good thermal conductivity, sufficient electrical resistance, and high elastic modulus. Therefore, tungsten rods are widely used in various fields. Such as support lines, lead-in lines, printer needles, various electrodes and quartz furnaces, filaments, high-speed tools, automotive automatic products, sputtering targets.
Supply form: rotary forging, turning polishing, polishing.
Processing method: sintering, forging, rotary forging, rolling, and polishing.
Classification of surface color of tungsten rods:
1. The surface of the sintered tungsten rod shows a silver gray metallic luster;
2. The forged tungsten rod has a layer of oxide on its surface, which is black in color;
3. Polished tungsten rod with a silver gray metallic luster.
