Graphite Crucibles for Melting Platinum HHGCA003

1 Material: High pure graphite 2 Size and shape: machine according to your drawing 3 OEM Factory

Shape and size:

Machine according to customers’ drawings.

Material:

100% graphite

Process:

Machined from high pure molded and fine grain size graphite blocks, on lathing machine, milling machine, with accurate machining. 

Machining tollerance: +/-0.05mm

Application:

The graphite crucible is mainly used in smelting copper, platinum, silver, gold, Jewelry and other ferrous metals and rare (precious) metals.

Advantage:

1. Without contamination of impurities

2. High resistance to high temperature, lower down oxidation speed.

3. Cutomized-machining is available in our factory. We could design and machine the graphite crucibles according to your application.
