What is tungsten steel alloy

Hard alloy is a kind of alloy material made of hard compound of refractory metal and bonding metal by powder metallurgy process.

Hard alloy has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at the temperature of 500℃ is basically unchanged, at 1000℃ still has a high hardness.

Hard alloy is widely used as tool materials, such as turning tool, milling cutter, planer, drill, boring tool, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel, can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult materials.

Tungsten steel (hard alloy) has high hardness, wear resistance, strength and toughness, good heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even at 500℃ temperature is basically unchanged, at 1000℃ still has a high hardness.

Tungsten steel, also known as hard alloy, is a sintered composite material consisting of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide are common components of tungsten steel. Carbide components (or phases) typically have grain sizes ranging from 0.2 to 10 microns, and carbide grains are held together using metal binders. Binder usually refers to the metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys may also be used. For an undetermined combination of carbide and binder components is called "brand".
