Graphite Crucible 1/2 / 3 / 4KG Metal Melting Gold Silver Scrap Casting Mould (2KG)

Eforlife -- Pure graphite crucible for metal melting and casting

*Important note: Pure graphite crucible can NOT be heating by Carbon furnace or charcoal kiln. It will be oxidized and cracked.

Composition: Graphite ≥ 99.9%; Ash≤0.1% (protect the precious metals from contamination while smelting)
Capacity:1kg/2kg/3kg/4kg/5kg Gold. 

►Features:

●Well thermal stability : Capable of fast heating and cooling according to the using conditions of graphite crucible. 
●Excellent corrosion resistance, impact resistance, acid resistance and alkali resistance.
●Great heat transfer performance: highly shorten the melting time and save energy.
●Small thermal expansion coefficient in high-temperature using process and certain strain resistance to the thermal shock, quenching.
●Graphite Crucible is Generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys. 
●Graphite is more durable than ordinary material products, which makes graphite crucible to have long service life under correct using condition.

►Warm-Tips: 

Stored in dry place, do not get it wet.
After drying the crucible, please avoid the water. 
Be careful not to give a mechanical impact force, not from a fall or impact.
