According to the knowledge provided, the main materials of carbide edge banding blades include tungsten carbide, titanium carbide and tantalum carbide.
Tungsten carbide carbide has high hardness and good wear resistance, so it is widely used in woodworking edge banding machines. When manufacturing tungsten carbide cemented carbide, tungsten carbide powder and metallic cobalt powder need to be mixed together, and then made into alloy materials through a powder metallurgy process.
Titanium carbide cemented carbide is a cemented carbide with titanium carbide as the main component. It has higher hardness and wear resistance, so it can replace tungsten carbide cemented carbide in some cases. The manufacturing process of titanium carbide cemented carbide is similar to that of tungsten carbide cemented carbide, but factors such as the particle size and purity of titanium carbide powder need to be controlled.
Tantalum carbide carbide is a cemented carbide with extremely high hardness and high temperature resistance, so it has good stability and wear resistance in high temperature environments. The manufacturing process of tantalum carbide cemented carbide is relatively complex. It requires the use of tantalum metal and tantalum carbide powder mixed together, and the alloy material is made through a powder metallurgy process.
In addition to the above three common cemented carbide materials, there are also cemented carbide with other metal elements as the main components, such as silicon nitride cemented carbide, titanium boride cemented carbide, etc. These cemented carbide materials have some special properties, such as high corrosion resistance, high strength and high thermal conductivity, and therefore are also used in certain specific fields.
