High heat conduction graphite crucibles for melting aluminum and copper

High heat conduction graphite crucibles for melting aluminum and copper   Product Description: We can provide the high pure graphite crucible, graphite clay crucible and graphite silicon carbide crucible to meet the different needs of customers. High purity graphite crucible is manufactured by high purity natural crystal graphite as raw material. It is widely used in melting of glass, precious metals, rare earth, zinc, silver, gold, ceramics etc. Graphite clay crucible is manufactured by natural crystal graphite and clay as main raw material. It is only used in high temperature melting of cast iron and cast steel, small amount precious metals melting. Graphite silicon carbide crucible is manufactured by natural crystal graphite and silicon carbide as main raw material. It is mainly used in melting of non-ferrous metals such as copper alloy and aluminum alloy etc.   Main features: 1. High heat Conduction: Use the higher thermal conductivity graphite, shorten the time of melting, and remarkably reduce the energy consumption. 2. Thermal shock resistance: can bear high thermal impact, not easy to break. 3. High heat resistance: High refractoriness, resistant to high temperature 1200 ~ 1600 ℃. 4. Corrosion resistance: Good molten metal corrosion resistance. 5. Excellent mechanical strength. 6. Resistance to oxidation. 7. Anti-adhesive: non stick and not infiltrate with molten metal. 8. Small metal pollution: Pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment. 9. Long working lifetime.   Size and shape: Standard type, long type, bowl type, lip type, electric furnace type. We can custom machined different size and shape according to the customer's requirement and drawing.   Related Products:    Packaging & Shipping: All products bind by plastic film, and covered by wooden case.
