2-choosing graphite and clay material, plastic into U-shaped
melting non-ferrous metal, like copper, aluminum, brass and iron, etc.
Silicon carbide graphite crucible
Mainly used in the melting of
non-ferrous metals, such as copper, aluminum, etc.It has the advantages of fast
heat conduction, high temperature resistance, good thermal stability and no
reaction with melting.
thermal conductivity of graphite and other raw materials, shorten the melting
Heat shock resistance: high
heat shock resistance, not easy to crack when cold or hot.
High heat resistance: high
temperature resistance, can withstand 1200~1650 high temperature.
