4 Pcs Graphite Ingot Mold Set

This package includes 4 pieces for metal melting and refining: 1 5-in-1 graphite casting ingot mold (72x57x12mm), 1 1kg graphite ingot crucible mold (100x50x25mm outer, 90x40x20mm inner), and 2 graphite stir rod sticks (30cm long, 0.8cm diameter). Suitable for non-ferrous metals such as gold, silver, copper, and aluminum. Features thermal stability, corrosion resistance, fast cooling, and high thermal conductivity to shorten casting time and save energy. Made of high-quality graphite with low ash content and high resistance to compression, flex, and density. Ideal for small-capacity metal refining projects.
