What Is Tungsten Carbide?

Tungsten carbide is a compound of tungsten and carbon, well known in industry for its superior durability and high melting point (2,870◦C). It is widely used in applications that require superior wear or impact resistance, such as abrasives, cutters, dies and punches.

When alloyed with carbon, the hardness of tungsten increases to 9.0 on the Mohs Scale (83-94HRA), which is just below that of diamond. This scratch-resistance is useful for making wear-resistant components, such as saw tips or drill tips, equipment used in brick and roof tile manufacture, or for crushing machinery. Its durability also makes it an ideal choice for components needed in the hostile undersea environment encountered by the oil and gas industry.

Tungsten carbide, also called WC, in industry it may be simply called carbide (titanium carbide and tantalum carbide also called carbide). In its natural state, it is a fine grey powder, which can either be sintered (compacted using heat or pressure) onto a surface, or cemented (bound with a metal to form a solid).

Tungsten carbide comes in grades, depending on which binders have been used – these are commonly cobalt or nickel, usually 6%-20% percentages of binders. Other carbides may be added in order to boost specific properties, especially with regards to density, hardness or transverse rupture strength.

Sichuan Precision Carbide is mainly supply tungsten carbide wear parts for pumps industry, oil & gas industry, centrifuges industry , sandblasting industry , cigarette machinery industry etc.
