Withstands continuous operation up to 1600°C (2912°F), providing significant safety margin above copper's melting point (~1085°C). Ensures stability during superheating, alloying, and extended holding times.
SiC structure excels at resisting cracks from rapid temperature swings, even at its 1600°C operational limit.
Graphite enables efficient heat transfer, significantly accelerating copper melt times and improving energy efficiency in induction, gas, or electric furnaces.
SiC forms protective silica layer, drastically slowing degradation in oxidizing copper melting atmospheres.
Resists erosion from molten copper/slag, withstands thermal cycling fatigue better than alternatives, minimizing carbon pickup into the melt.
Maintains integrity against common copper fluxes and oxides, ensuring consistent performance.
