WHY CHOOSE US

Product advantage: Compared with other sic crucibles

1 For die casting industry

We use advanced graphite silicon carbide material, specially developed for the die casting industry, more suitable for low temperature environment. Excellent oxidation resistance in low temperature environment, extending the service life by 20%. The thermal conductivity is 17% faster than the traditional silicon carbide graphite crucible, and the energy saving effect is significant and more environmentally friendly. More stable performance in die casting environments, reduced replacement frequency and lower customer costs.

2 For aluminum casting industry

Optimized on the basis of traditional European sic crucible formulations to further improve the antioxidant performance. We can ensure that the sic crucible itself does not gas out, protect the purity of the liquid aluminum, and provide customers with higher quality casting products. Excellent corrosion resistance in aluminum casting environments and extended service life.

3 For the recycled aluminum industry

Our silicon carbide crucibles is particularly outstanding in the recycled aluminum industry, and its corrosion resistance is far better than that of similar crucible silicon carbide, and its service life is increased by more than 20%. Effectively reduce the frequency of replacement, reduce customer operating costs.

4 For electromagnetic induction furnace

The traditional silica carbide crucible is usually not magnetic conductive on the electromagnetic induction furnace, and our specially developed new material silicon carbide crucibles has its own heating performance, significantly improving the heating efficiency. The service life of electromagnetic induction furnace can reach more than a few years, far exceeding the industry average level.

FAQS

Q1: What are the advantages of silicon carbide graphite crucibles compared to traditional graphite crucibles?

✅ Higher Temperature Resistance: Can withstand 1800°C long-term and 2200°C short-term (vs. ≤1600°C for graphite).
✅ Longer Lifespan: 5x better thermal shock resistance, 3-5x longer average service life.
✅ Zero Contamination: No carbon penetration, ensuring molten metal purity.

Q2: Which metals can be melted in these crucibles?
▸ Common Metals: Aluminum, copper, zinc, gold, silver, etc.
▸ Reactive Metals: Lithium, sodium, calcium (requires Si₃N₄ coating).
▸ Refractory Metals: Tungsten, molybdenum, titanium (requires vacuum/inert gas).

Q3: Do new crucibles require pre-treatment before use?
Mandatory Baking: Slowly heat to 300°C → hold for 2 hours (removes residual moisture).
First Melt Recommendation: Melt a batch of scrap material first (forms a protective layer).

Q4: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).

Q5: How to prevent crucible cracking?

Never charge cold material into a hot crucible (max ΔT < 400°C).

Cooling rate after melting < 200°C/hour.

Use dedicated crucible tongs (avoid mechanical impact).
