Product Description

Accept customize any size of graphite ring sleeve, ODM OEM is available !

Crucibles for melting gold are usually made from superior garde graphite material and can be widely used in different kinds of furnaces . The gold melting crucible can be used to melt gold as well as silver and other metals such as aluminium, copper, brass, iron, zinc, lead, etc. A crucible for melting gold can be properly maintained and can last a very long time without any form of crack.

Graphite crucible is used for melting and casting of metals and certain alloys. This is the part of the induction furnace that holds molten metal during melting processes. The crucible is made up of graphite which makes it a high quality induction furnace graphite crucible. The high density body of the furnace crucible and its structure makes the furnace crucible a better compression property.
