High purity (99%) heat resistant graphite crucible with flat bottom. Maximum casting capacity: 20 kg, good for use with induction heating, recommended for precious metals casting. Compatible with 25kW low-frequency induction heaters for melting manufactured by Across International.
Graphite, often called black lead, can tolerate thermal shock and withstands constant working temperature up to 1500°C or 3600°C (vacuum condition). They are the best electrical conductive material known to man, 4 times of steel, 5 times of copper and 100 times of non-metallic materials. They also have higher thermal conductivity than steel, iron and lead, plus resistant to acid, alkali and organic solvent.
