Tungsten Carbide Cutting Tools Composition

Cemented carbide is a hard material used extensively as cutting tool material as well as other industrial applications.

Tungsten carbide cutting tools composition.

Small tungsten carbide cutting tools single flute spiral end mill for wood router machine. Tungsten carbide also often referred to as hard metal is a composite material fabricated by powder metallurgy which consists of one or more hard material phases e g. Hss tools have a harness of 62 64 rc. A typical hss composition is.

Tungsten carbide itself hereafter referred to as wc and a binder metal surrounding the hard material grains e g. Cemented carbides commonly use tungsten carbide wc titanium carbide tic or tantalum carbide tac as the aggregate. Higher machining speed tungsten carbide inserts metal cutting tools. It consists of fine particles of carbide cemented into a composite by a binder metal.

Anticorrosive cnc milling machine cutting tools indexable carbide end mill 2 flute. At the same time meeting the requirements of the market quickly and forging a strong cemented carbide tools enterprise with the enterprise spirit of pursuing a perfect mastery and achieving success with sincerity. Other materials such as titanium carbide tantalum carbide and niobium carbide are added to improve the properties of the material when cutting. In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery.

The tungsten carbide goes into a mixing vessel with the other components of the grade. Powdered cobalt metal will act as the glue to hold the material together. Rigidity tungsten carbide compositions range from two to three times as rigid as steel and four to six times as rigid as cast iron and brass. Cobalt co or nickel ni.

The addition of 5 to 8 cobalt to hss imparts higher strength and wear resistance. Small diameter cnc end mill bits carbide ball nose end mill for aluminum. High speed steel is a high carbon tool steel containing a large dose of tungsten. Tungsten carbide wc and cemented carbides which are composed of wc with a binder phase represent crucial materials for the fabrication of hard wear resistant tools across a wide range of industrial applications.

Tungsten carbide is the most widely used type of high speed machining hsm tool material produced by powder metallurgy consisting of hard carbide usually tungsten carbide wc particles and a softer metal bond.
