650g Graphite Ingot Mold Metal Casting Mold Melting Crucible Furnace for Gold Silver Aluminum Copper Brass Zinc Alloy

Feature:
【Composition:】
99.95% Graphite, content less than 0.1%.
Excellent thermal conductivity and corrosion resistance.
Better for Refining than Silicon Carbide Graphite Crucibles.
【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.
【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 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, Zinc, Plumbum, etc
