Graphite crucible Metal casting Pouring mould to Melt metals gold silver
High purity graphite: 99.99% purity, non-stick metal when smelting metal, low loss, save cost for you!
Selected special materials can make our graphite crucible products more than 2 times durable than ordinary materials products,
longer service life, and more able to withstand the high temperature of more than 2000 degrees Celsius!
At the same time, it has the following characteristics:
1. Good thermal stability: For the use of graphite crucible hot and cold conditions, special formula.
2. Good corrosion resistance and impact resistance to ensure the reliability of product quality.
3. Good acid and alkali resistance.
4. Good heat conductivity: It can greatly shorten the smelting time and save energy.
6. Ash less than 300 PP to ensure that noble metals are not contaminated in smelting
