Suprex

Suprex crucibles are carbon-bonded silicon carbide crucibles, which are characterized by excellent thermal conductivity and high chemical erosion resistance. Based on application and furnace type respective types of Suprex are available.

Applications

Suprex B: Recommended for copper and copper alloys in fuel fired furnaces

Suprex R: Recommended for aluminium /aluminium alloys melting and zinc oxide producing in fuel fired furnaces

Suprex E: Recommended for aluminium /aluminium alloys and zinc melting and holding in electric resistance furnaces

Suprex Typical Metal Casting Temperature 

Suprex B 800°C - 1400°C (1472°F - 2550°F)

Suprex R 700°C - 1000°C (1292°F - 1830°F) 

Suprex E 450°C - 900°C (842°F - 1652°F) 

Suprex E - Plus 450°C - 900°C (842°F - 1652°F) 

Performance Characteristics

  • Fast melting speed through high consistent thermal conductivity
