Graphite Ingot Mold Metal Casting Mold Cross-Melting Crucible Furnace for Gold Silver Aluminum Copper Brass Zinc-Alloy

Features: Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles. Perfect 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 for-time and save energy; Great impact resistance performance to ensure the reliability of product quality. Application:Used for melting and casting metals .such as Gold, Silver, Brass, Aluminum, Copper, Plumbum, etc. 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 ℉ (400℃). The-withstand temperatures can be 3200 ℉ if you use Air Electric Furnace. The-withstand temperatures can be 5000 ℉ if you use Vacuum or-Gas for Protection Furnace.
