Tungsten carbide is a metal material which is made of refractory metal carbides and binder by powder metallurgy. Tungsten carbide is very hard and wear-resistant while the Coblat is very soft. Cobalt as a binder to bond the tungsten carbide particle tightly. Thus can guarantee the road milling bits tips not fail even under the maximal stress.
The quality of the carbide tip determin the service life of the asphalt milling teeth. Balanced mixture of tungsten carbide particles largely determines the wear-resistance of the carbide tips.
