Steel Discs

Precision formed curved steel discs placed at the bottom of the mould crucible to hold the welding powder until optimal reaction temperature is reached.

• Precision pressed steel disc with engineered curvature for seamless crucible seating.
• Specially calibrated thickness ensuring release of molten metal at the exact thermite melting point.
• Prevents unreacted welding powder from entering the conductor weld cavity.
• Ensures optimal temperature and purity of molten copper for superior weld bond.
• Supplied in multiple diameters matching cartridge sizes from 45g to 250g.
