High purity heat resistant graphite stirring rod. Good for use with induction melting or precious metal casting.
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.
