Compared with traditional silicon carbide, carbide has more stable chemical properties, such as good wear resistance, high thermal conductivity, low coefficient of friction, small coefficient of expansion, acid resistance, alkali resistance, self-lubrication, corrosion resistance, high thermal conductivity and small expansion coefficient, making it an ideal material for mechanical wear-resistant parts.
Our products range of customized wear parts:
