composition: W + 2% cerium

• The WC20 cerium-coated MMA is the universal electrode for almost all applications:

  Direct current and alternating current, unalloyed steel, high-alloyed steel, aluminium alloys, titanium alloys, nickel alloys, copper alloys and magnesium alloys

• This MMA is a good alternative to thoriated electrodes, with the main advantage being its long service life, good current carrying capacity and environmental compatibility
