2 Pieces Graphite Ingot Mould Crucible Mould for Casting Gold Silver Metal Aluminum Copper Brass Melting Refining (4 x 2 x 1 Inch)
- Reliable material: main material is graphite, the ash content is less than 0.1 percent, ensuring that the metal purity will not be affected during metal refining.
- Rapid cold and hot use conditions, with nice thermal stability.
- Nice characteristics: it has nice thermal conductivity, which can greatly shorten the melting time and save energy, and withstand 2000 degrees Celsius, nice acid and alkali resistance, nice corrosion resistance, impact resistance, 89 MPA compression resistance, and 48.7 MPa flex resistance.
- Widely applicable: the mould can be applied for experiments and smelting of non-ferrous metals, such as gold, silver, copper, aluminum, and so on.
- Considering the size of this product, it is more suitable for small-capacity metal melting.
- Ingot mould size: 1KG graphite ingot mould outer is 100 x 50 x 25 mm/ 4 x 2 x 1 inch, inner is 90 x 40 x 20 mm/ 3.54 x 1.6 x 0.8 inch.
- 2KG graphite ingot mould outer is 100 x 60 x 40 mm/ 3.93 x 2.36 x 1.57 inch, inner is 85 x 45 x 30 mm/ 3.35 x 1.77 x 1.18 inch, melting and casting metals like gold, silver, brass, aluminum, copper, zinc, plumbum, and more.
- The capacity is an approximate volume is 1 kg hold or 500g silver.
