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.

Hard alloy rod, also known as hard alloy round rod or tungsten steel rod, is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy process. Hard alloy rods have extremely high hardness and wear resistance, with hardness comparable to diamond and excellent wear resistance. In addition to high hardness, hard alloy rods also have good strength and toughness, and can withstand large mechanical stresses and impacts.
