Silicon carbide crucibles are manufactured using silicon carbide as the primary raw material through a specialized process. Offering superior wear and corrosion resistance as well as an extended service life, they are widely used in modern foundries that prioritize high quality and large-scale production.
Key Applications:
High-efficiency copper alloy melting: Ideally suited for melting brass, bronze, and cupronickel; silicon carbide withstands the high temperatures required for these metals
(up to 1600°C or higher).
Large-scale melting of aluminum and aluminum alloys: Used for bulk melting of molten aluminum in automotive component manufacturing and die-casting plants.
Melting low-melting-point metals (zinc, lead, tin, etc.): Exceptional wear resistance and low contamination potential ensure high purity of the molten metal.
Precious metal melting: Suitable for the refining and processing of metals such as gold and silver.
Applicable Industries and Furnace Types:
Die-casting and foundry industries: Automotive wheel manufacturers, engine component plants, and manufacturers of plumbing and sanitary valves.
Compatibility with advanced industrial furnaces: Commonly used in induction furnaces (electromagnetic furnaces), resistance furnaces, gas-fired furnaces, and oil-fired furnaces.
It offers excellent response to electromagnetic induction and ensures highly uniform heating.
