Features
- Different usages: graphite casting ingot mold can be applied for experiments and smelting of non-ferrous metals, including gold, silver, copper, aluminum, and so on, which can also be applied as graphite crucible melting into non-ferrous metals, test analysis, as the ingot mold and other purposes; Considering the size of this product, it is more suitable for small-capacity metal melting
- Works well: nice thermal stability for withstanding 2000 degrees Celsius, fast cooling, nice corrosion resistance to strong acid and alkali, nice thermal conductivity properties which highly shorten the casting time and save energy; It keeps its natural graphite of various physical and chemical properties; This mold is ideal for making several bars at the same
- Reliable material: mainly made of graphite, these molds are with hardness 51 HSD, 89 MPA compression resistance, 48.7 MPa flex resistance, bulk density 1.86 g per cubic cm, ensuring that the metal purity will not be affected during metal refining; Nice thermal conductivity and corrosion, well heat transfer
- Nice temperature resistance: graphite crucible let the products more durable than ordinary material products, which can withstand more than 2000 degrees Celsius high temperature
Description
The mold has 3 rectangular slots and 2 round holes, suitable for melting and casting bars or coin metals, gold, silver, copper and other alloy tool steel. It applied for experiments and smelting of non-ferrous metals, also applied for graphite crucible melting into non-ferrous metals, test analysis, as the ingot mold and other purposes. The size is more suitable for small-capacity metal melting, and ideal for making several bars at the same. Nice thermal stability Nice corrosion resistance and impact resistance Good thermal conductivity Does not contaminate metals Read more 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 cracked. 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.
