Tungsten Carbide Cutting Tools Composition

High speed steel is a high carbon tool steel containing a large dose of tungsten.

Tungsten carbide cutting tools composition.

Small tungsten carbide cutting tools single flute spiral end mill for wood router machine. 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. 18 tungsten 4 chromium 1 vanadium 0 7 carbon and the rest iron. A typical hss composition is.

The tungsten carbide goes into a mixing vessel with the other components of the grade. Young s modulus is up to 94 800 000 psi. Tungsten carbide itself hereafter referred to as wc and a binder metal surrounding the hard material grains e g. Other materials such as titanium carbide tantalum carbide and niobium carbide are added to improve the properties of the material when cutting.

Powdered cobalt metal will act as the glue to hold the material together. It consists of fine particles of carbide cemented into a composite by a binder metal. The addition of 5 to 8 cobalt to hss imparts higher strength and wear resistance. 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.

Small diameter cnc end mill bits carbide ball nose end mill for aluminum. Higher machining speed tungsten carbide inserts metal cutting tools. 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.

Hss tools have a harness of 62 64 rc. Cemented carbides commonly use tungsten carbide wc titanium carbide tic or tantalum carbide tac as the aggregate. Anticorrosive cnc milling machine cutting tools indexable carbide end mill 2 flute. We mainly produces tungsten carbide welding blade grit pellet composite welding rods strips plate ball tooth etc.

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.
