Applications of Tungsten Carbide

Tungsten Carbides have a wide range of application in many industry sectors such as metal machining, wear parts for mining and oil industries, metal forming tools, cutting tips for saw blades and have now expanded to include consumer items such as wedding rings and watch cases, plus the ball that is in many ball point pens.

Application Industries:

- Paper

- packaging

- printing

- Non-ferrous metal processing

- Mechanical

- Chemical

- Petroleum

- Metallurgy

- Electronic

- Defense industries

Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness in relation to other metals. Typically a Tungsten Carbide can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a factor of 10 lower.

How tugnsten carbide rod is made:

Tungsten Carbide Hard Metals are primarily produced using a Powder Metallurgy process, whereby the powdered forms of tungsten carbide and cobalt are mixed using ball mills, a binder material is added to hold the powders together during the next stage of the process which is compaction or pressing.

During the compaction processes, hydraulic presses or isostatic presses are used to compact the powders into a shape which approximates the design of the finished product.

Whilst in this condition, the powder compact can be easily machined using conventional metal working tools. This process is often referred to as “Green Machining”. Care has to be taken with the removal of the fine powder particles as they can pose a health hazard so effective extraction methods are required.

Following “Green Machining” the powder compact is then ready to be Sintered. Typically this is done in a vacuum furnace at temperatures between 1300 and 1600°C.

The sintering process causes the tungsten carbide and cobalt matrix to fuse together to produce a dense “Hard Metal”.

After sintering the material is so hard that it can only be machined by diamond grinding, a specialised form of micro machining that is relatively expensive as it is not possible to remove large amounts of materials by this process.
