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.

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.
