Ingot Mold, 60ml Capacity Crucible Mould, 2Packs Metal Casting Molds for Casting Melting Refining

Graphite Ingot Mold, 60ml Capacity Crucible Mould, 2Packs Metal Casting Molds for Casting Melting Refining Gold Silver Aluminum Copper Brass Zinc Plumbum and Alloy (2"x2"x2" - 1000g Gold; 540g Silver) Dimensions: 3.1' 2.4' 5.1' Size: 2"x 2"x2", 2Packs Brand: A.I.FORCE [PREMIUM MATERIAL] - The ingot mold is made of 99.95% Graphite and ash content less than 0.1% which ensures that the metal purity will not be affected during metal refining. The metal casting molds feature with nice thermal stability and suitable for rapid cold and hot working conditions. The durable graphite ingot molds have a long working life and can be used as more as 20,000 times. Better than Silicon Carbide Graphite Crucibles. [INGOT MOLD SIZE] - Outer Dimension 1.97x1.97x1.97inch(50x50x50mm), inner dimensions 1.57x1.57x1.77inch (40x40x45mm). Volume 60ml. Capacity: 1000g Gold or 540g Silver. [HIGHLIGHT FEATURES] - Completed with good thermal conductivity, the ingot molds can greatly shorten the melting time and save energy. The premium graphite ingot molds can withstand up to 3600 °F (2000 ℃). Strong acid and alkali resistance, good corrosion resistance, impact resistance, 75MPA compression resistance, and 55MPa flex resistance. [WIDE APPLICATION] - The metal casting molds can be applied for experiments and smelting of non-ferrous metals, such as gold, silver, copper, aluminum, lead and more. The ingot molds can also work as graphite crucible for melting into non-ferrous metals, test analysis, or other purposes. [WARM TIPS] - Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. If so, the metal casting molds will soon be oxidized and cracked. Pure graphite will start to oxidize at 752 °F (400 ℃). The withstand temperatures of graphite crucible can be 3200 °F in Air Electric Furnace and 5000 °F in Vacuum or Gas Protection Furnace.
