Material The main material is graphite, the ash content is less than 0.1 percent, which ensures that the metal is not affected during metal refining Fast cold and hot use conditions, with thermal stability, better refining effect than silicon carbide graphite crucibles Features It has thermal conductivity, which can greatly shorten the melting time and save energy, and can withstand 2000 degrees Celsius, acid and alkali resistance, corrosion resistance, impact resistance, 89 MPA compressive strength and 48.7 MPa bending strength Wide use The mold can be used for eperiment and melting of nonferrous metals, such as gold, silver, copper, aluminum, lead and so on It can also be used as graphite crucible melting in nonferrous metals, test analysis, as a casting mold and other purposes Considering the size of this product, it is more suitable for smallcapacity metal melting. Casting mold size Outer is 1005025 mm, inner is 904020mm Melting and casting of metals such as gold, silver, brass, aluminum, copper, zinc, lead and more The capacity is an approximate volume is 1kg hold or 500g silver What you get There are 2 pieces of graphite casting molds in this package, enough for use, improving your work efficiency in Color black Material graphite Size 904020mm 1005025 mm Package contents 2Graphite Casting Mold Only the above package contents, other products are not included.
