• Package 1x Graphite Casting Melting Ingot?Different Size?you can choose).Composition: 99.95% Graphite. Ash content less than 0.1%. Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
• Performance Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong acid and alkali / Good thermal conductivity properties which highly shorten the melting time and save energy / Great impact resistance performance to ensure the reliability of product quality.
• Warm-Tips Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. It will be oxidized and cracked; Pure graphite will start to oxidize at 752 °F ?400?). The withstand temperatures can be 3200 °F if you use Air Electric Furnace. The withstand temperatures can be 5000 °F if you use Vacuum or Gas Protection Furnace. Application Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
