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).
