Product Description

Features: Characteristics of the mould: Crucible mould has nice thermal conductivity and high temperature resistance, which efficiently reduces melting time and saves energy, and can withstand 2000 degrees Celsius, as well as other features such as acid and alkali resistance, nice corrosion resistance, 89 MPA compression resistance, 48.7 MPa flex resistance and so on, nice impact resistance makes the mould able to be applied for a long time. More usages: This ingot mould is ideal for experiments, as graphite crucible for melting of non-ferrous metals, such as gold, silver, brass, copper, aluminum zinc, and so on, or test analysis and other purposes; To take the size of the product into account, small-capacity metal melting are more suitable. Specifications: Outside dimension: approx. 100 x 50 x 25 mm Inside dimension: approx. 90 x 40 x 20 mm Color: as the picture shows Main material: graphite Package includes: 3 x Graphite ingot mould Note: Manual measurement, please allow slight errors on size. The colors may exist slight difference due to different screens. Pure graphite crucible can not be heated by carbon furnace or charcoal kiln. It will be oxidized and broken. Pure graphite will start to oxidize at 752 degrees Fahrenheit/ 400 degrees Celsius. The withstand temperatures can be 3200 degrees Fahrenheit if you use air electric furnace. The withstand temperatures can be 5000 degrees Fahrenheit if you use vacuum or gas protection furnace.

• "Details for size: the outside dimension of graphite ingot mould measures approx. 100 x 50 x 25 mm and the inner size is about 90 x 40 x 20 mm, with the capacity of 1 kg gold or 500 g silver approximately, suitable size satisfies your needs of melting or casting different kinds of metals" • "Nice material: the main material of the silver gold casting ingot crucible mould is graphite, little ash content keeps the metal purity not being affected during the metal refining process; In fast cold and hot conditions, they are featured with nice thermal stability, and provide nice metal refining effect" • "Product features: crucible mould has nice thermal conductivity and high temperature resistance, which efficiently reduces melting time and saves energy, and can withstand 2000 degrees Celsius, as well as other features such as acid and alkali resistance, nice corrosion resistance, 89 MPA compression resistance, 48.7 MPa flex resistance and so on, nice impact resistance makes the mould able to be applied for a long time" • "Applicable for: this ingot mould is ideal for experiments, as graphite crucible for melting of non-ferrous metals, such as gold, silver, brass, copper, aluminum zinc, and so on, or test analysis and other purposes; To take the size of the product into account, small-capacity metal melting are more suitable" • "What are contained: package comes with 3 piece of graphite ingot moulds for you, completed with carefully workmanship and possessing extensive usages, meeting your daily metal melting, casting and refining need, sufficient amount can increase your efficiency, also support your sharing requirement, invite your friends or family to enjoy handmade fun together"
