Furnace Torch Melting Casting Refining Gold Brass

• Composition: 99.9% . Ash content less than 0.1%.
• Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Crucibles.
• Performance: Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong 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.
• Application: Melting and casting metals such as Gold Silver Brass Aluminum Copper Zinc Plumbum etc.
• Attention: Pure crucible can NOT be heating by carbon furnace or kiln. It will be oxidized and cracked Pure 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.
