Mainly used for the melting of aluminum, aluminum alloy, zinc alloy and frying aluminum ash.

- Excellent resistance to low temperature oxidation, which makes the crucible have good thermal conductivity for a long time, and at the same time effectively prevent the strength deduction caused by oxidation.
- Special material design, excellent crack resistance, to prevent cracks in use.
- Iron-free material design to prevent iron from melting into the aluminum melt to contaminate the aluminum melt.
