Tungsten carbide wear parts

Tungsten carbide wear parts Tungsten carbide wear parts Tungsten carbide wear parts

Tungsten carbide is widely used in industry because of its extraordinary properties. Because of its wear resistance and hardness (9.8 Moe's scale), tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.

A large portion of the tungsten volume in cemented carbide is today used in wear part applications, where there is a wide range of products from the very small (such as balls for ball-point pens) to large and heavy products, such as punches, dies or hot rolls for rolling mills in the steel industry.

Most of this tungsten carbide wear parts and the mining tools are made of straight WC-Co hard metals without any addition of other carbides.
Fine and ultrafine grained WC hard metals have become more and more important today in the field of wear parts, tools for chipless forming and cutting tools for cast iron, non ferrous alloys and wood.

The first submicron hard metals were launched on the market in the late 1970s and, since this time, the micro-structures of such hard metals have become finer and finer. The main interest in hard metals with such finer grain sizes derives from the understanding that hardness and wear resistance increase with decreasing WC grain size.

Various grades and Sintered Tungsten Carbide Wear Parts for metal forming and Wear resistant applications are available in the following range.

MECHANICAL SEAL RINGS

Tungsten Carbide Seal Rings are used as Mechanical Seal faces in pumps, Compressors and Agitators. These are used in Oil Refineries, Petrochemical plants, Fertilizer Plants, and Drugs/Pharmaceutical Industries.

Mechanical seal rings are developed to withstand high temperature, high pressure & highly corrosive chemical attack. We manufacture Rings in various shapes like Plain Ring, DA type, T-shape, L-shape and in shapes as per customers’ requirement.
Tungsten Carbide Rings are generally made with Cobalt as binder material. Nickel bonded Rings also can be supplied.

PELLETS / NIBS

To serve the metal drawing Industry, we manufacture tungsten carbide wire, bar and tube drawing pellets. A high hardness combined with good toughness is provided to withstand extremes of temperature and pressure. The wear resistance property of tungsten carbide wear part can lead to extended die life while achieving desired quality of material drawn such as surface finish and dimensional accuracy.

JUTE EYELETS

Tungsten Carbide wear parts used in spinning and weaving machinery particularly in jute industry are eyelets. These are to prevent vibration/ deflection of jute thread at high speed. Tungsten Carbide jute eyelets give long uninterrupted running of the machine.

Tungsten carbide jute eyelets are available in different sizes and shapes namely Half moon, Flyer leg Insert, N-K eye, P/spindle eye, N-K strip, Small carbide eye, Big carbide eye, Nozzle eye, etc.

Tungsten carbide parts we can supply for you as follows:

  • die-set for cold punching & stamping
  • rectangular bar with different size
  • HM round bar with different D &L
  • Tooth for all kinds of saw
  • HM drawing die
  • sealing ring, wear-resistance parts
  • Heads for electric drills
  • HM balls with different OD
  • fabric parts, mechanic parts, nozzle etc. wear-resistance and re-abrasive parts
