Product Description

What is graphite crucible?
A graphite crucible is a container used for melting and casting non-ferrous, non-iron metals such as gold, silver, aluminum, and brass. Their thermal conductivity, high temperature resistance, small thermal expansion coefficient for high temperature applications, and anti strain properties to rapid heating and cooling make graphite crucibles an ideal metal casting solution. They are resistant to the effects of acids and alkaline solutions and have excellent chemical stability.
Why does graphite matieral suitable for smelting and casting for jewelry industry and other industry?
The crucible is made from high quality graphite which makes the graphite crucible to have a good thermal conductivity, resistant to acidity and alkalinity and a high temperature resistance, therefore, ensuring quality of products.
Graphite crucibles do not contaminate molten metals because the graphite material is fused and does not loosen. The quality of a graphite crucible is determined by how it is manufactured, which influences its structure, density, porosity, and strength.
As the graphite has an excellent heat performance, the time spent on melting is short, therefore saving energy.Their excellent heat performance helps in melting metals quickly for faster production cycles.

Since graphite crucibles are resistant to chemicals and corrosion, they are not affected by workshop conditions, characteristics that make them durable and long lasting.
So graphite crucible is suitable for foundries, jewelry industry and other industries where metal melting and casting is necessary.
