Hard alloy rods can maintain stable performance at high temperatures and have excellent corrosion resistance, making them suitable for long-term use in harsh environments. Hard alloy rods also have the characteristics of good red hardness, high elastic modulus, strong bending strength, and good chemical stability (acid, alkali, high temperature oxidation). Widely used in various cutting materials such as turning tools, milling cutters, planers, drills, boring cutters, etc., including cast iron, non-ferrous metals, plastics, synthetic fibers, graphite, glass, stone, and ordinary steel.

Tungsten rods use special high-temperature powder metallurgy technology to compress and sinter metal powder at high temperatures. Low coefficient of thermal expansion: In high-temperature environments, the thermal expansion coefficient of tungsten alloy rods is relatively low, which helps to maintain the dimensional stability of the material. Tungsten rods have good thermal conductivity, which helps with rapid heat transfer and dispersion. Tungsten is one of the metals with extremely high melting points, which enables tungsten alloy rods to maintain stable performance even in high temperature environments.
