4pcs Graphite Crucible Set, Ingot Mold Set High Purity Graphite Torch Melting Casting Kit

4pcs Graphite Crucible Set, Ingot Mold Set High Purity Graphite Torch Melting Casting Kit for Non-Ferrous Metal,Gold,Silver and Copper Quartz crucible: Graphite crucible is used to stir precious metals and metal scraps during melting. When melting gold and silver, this rod can help you get a uniform mix. The crucible can withstand high temperatures up to 2800 degrees. High-quality materials: Modern ceramic processing technology is used, and high-quality fused silica is selected as the main raw material. Graphite crucible has good thermal conductivity and high temperature resistance. In high temperature use, the coefficient of thermal expansion is small, and it has a certain resistance to rapid heat and cold. Uses: Mainly used for high temperature melting alloys such as dental alloys, platinum, gold, silver, copper and brass. High temperature resistance up to 2800 degrees, high purity, corrosion resistance, high strength, high heat resistance, high shock resistance. Wide range of applications: It is a good flux for impact welding and metal testing. It has a wide range of uses and can be used in experiments and smelting of non-ferrous metals. Such as gold, silver, copper, aluminum, lead, etc. Considering the volume of the product, it is more suitable for small-volume metal smelting. Crucible tongs: non-slip design, firmly clamp the crucible, not easy to slip off. All raw materials are carefully selected through multiple links. Good thermal conductivity, fuel saving, money saving and environmental protection. The graphite melting kit contains four items. You can check the size on the detail page before purchasing.
