SiC Graphite Crucibles For Melting Aluminium And Copper, Brass
Product Description
Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :
1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.
2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.
3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.
4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.
5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.
6.High-strength: high-density body and logical structure make the product better compression property.
7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.
8.Multi-function: Can be used in induction graphite crucible furnace
