Pure Graphite Crucible Metal Melting Gold Silver Scrap Casting Ingot Mould (5KG – Fit a Coke Can)

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.

Package Content:
1x Graphite Crucible (well packaged)

?Size?Capacity: 5KG gold; Inner diameter: 69mm (larger than coke can); Height: 130mm (taller than coke can)
?Composition:?99.9% Graphite. Ash content less than 0.1%. Excellent thermal conductivity and corrosion resistance. Better for Refining than Silicon Carbide Graphite Crucibles.
?Application?Melting and casting metals such as Gold, Silver, Brass, Aluminum, Copper, Zinc, Plumbum, etc.
?Performance?Excellent thermal stability for fast heating and cooling / Well corrosion resistance to strong acid and alkali / Good thermal conductivity properties which highly shorten the melting time and save energy / Great impact resistance performance to ensure the reliability of product quality.
?Attention?Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. It will be oxidized and cracked; Pure graphite will start to oxidize at 752 °F ?400?). The withstand temperatures can be 3200 °F if you use Air Electric Furnace. The withstand temperatures can be 5000 °F if you use Vacuum or Gas Protection Furnace.
