Tungsten carbide tip tools are made by transforming tungsten ore into tungsten carbide. During this process, the tungsten turns into a hardfacing alloy. The composition of a typical hardfacing alloy is 50 to 60 percent WC, with a minimum of 2% Si. The remaining components are Fe, Cr, Mo, and Ni. The resulting tool is extremely hard, and the sintering process results in very little surface wear.
In the early years of carbide cutting tools, tungsten carbide was first used as a base material for steel. However, it soon became apparent that carbide is not as versatile as diamond. This alloy has extremely high compressive strength, high rigidity, and excellent heat properties retention. The tool is also very hard, with a high degree of dimensional stability and twice the hardness of steel.
Generally, tungsten carbide tip tools are made of two primary components: tungsten carbide and cobalt. The tungsten carbide is mixed with other materials to make it more efficient. Powdered cobalt metal is used as the “glue” that holds the tungsten carbide together. The cobalt is added to improve the cutting capacity of the tungsten carbide.
In early years of carbide tip manufacturing, brazing was used to join the tungsten carbide tips to steel. The process is relatively inexpensive and works well for small-area, short-length joints. It also takes advantage of capillary action. The alloy bonds with the tungsten carbide surface and forms a solid bond. The difference between welding and brazing is the method used for jointing large pieces of tungsten carbide.
Tungsten carbide powder is a type of tungsten carbide powder. It is a particle of about half a micron in size. These particles are sorted through sieves into different grains. They are then blended into grade powder. The tungsten carbide industry uses the terms grades and alloys to define the resulting tungsten carbide tip. The various parts of the tool are used to cut things.
The tungsten carbide tip tools are made by mixing tungsten carbide with other materials that improve their cutting properties. The resulting material will be harder than the steel itself, and will cause craters in the material it cuts. Tungsten carbide without the addition of additives can produce a tool that will leave a crater in the material it is cutting. A properly-made tungsten carbide tip tool will last for years.
Tungsten carbide is used for cutting tools. Although tungsten carbide is cheaper, it can crater more easily, so it is recommended to use a different kind. A tungsten carbide saw blade is likely to be a tungsten carbide saw blade, and it is technically incorrect to call it a carbide. This is because the saw blades are made of a mixture of carbon and super-hard metal.
