MAGMA has been committed to supplied world class Iso-pressed graphite silicon carbide Crucibles for long time. We have most advanced Iso-pressor and other advance facilities to make good final products. Our products are widely used in diversified areas, with magnificent practices in foundry industry.
This kind of kiln furniture is kind of Composite Material which utilize fully of the high strength, high abrasion of SiC phase and high Creep resistance, high thermal shock resistance of Mullite phase. The material can serve in the temp. up to 1400℃ withstanding high load and high thermal shock situation.
