Alucy 1Kg 2Kg 3Kg Graphite Crucible Metal Melted Gold and Silver Scrap Steel Furnace Casting Mold Melt Used to Melt Gold and Silver Tools 1Kg - B07RYYP7CW [High Temperature] The original natural graphite retaining various physical and chemical properties is only applicable to electric furnaces. Pure graphite crucibles cannot be heated in coal or carbon furnaces. This jewelry making tools will rust and break; pure graphite will begin to oxidize at 752 °F (400 °C). If an air heater is used, the temperature can withstand temperatures up to 3200 °F. [Application] Our graphite crucible can melt alloys such as gold, silver, platinum and other precious metals, and has a long service life. [Thermal Stability] This casting mold melting gold and silver graphite crucible has good thermal stability and is suitable for emergency or cold conditions. [Ingredient] This melted gold and silver scrap steel furnace with 99.9% graphite. The ash content is less than 0.1%. Excellent thermal conductivity and corrosion resistance. More suitable for refining graphite crucible made of silicon carbide. [Function] Graphite crucible has good thermal conductivity, rapid heating and cooling / good acid and alkali resistance / significantly shortens the melting time, saves energy / impact resistance, and ensures product quality reliability.
