The graphite crucibles used for metal casting are specially designed for the melting and casting of metals such as iron, aluminum and copper. They feature high thermal stability and an extremely long service life, significantly enhancing the quality of the castings and production efficiency.
In the field of metal casting, graphite crucibles used for metal casting are the core equipment for melting basic metals such as iron, aluminum, and copper to produce castings. The measured data shows that their thermal expansion coefficient at a high temperature of 2150°C is only 1.0×10⁻⁶/°C, which is 50% lower than that of traditional metal crucibles. This effectively reduces the non-uniformity of melting and significantly improves the density and mechanical properties of the castings.
The service life of graphite crucibles used for metal casting can reach up to 800 times (compared to only 250 times for traditional metal crucibles), and the purity of molten iron can be increased by 16% (far exceeding the 12% of stainless steel crucibles). This performance data is derived from the on-site test report of the International Foundry Association (ICA) in 2024, fully demonstrating its outstanding durability and reliability in high-temperature cycling environments.
In addition, the graphite crucibles used for metal casting have obtained ISO 9001 quality certification and are specifically designed for precision casting scenarios such as automotive components and mechanical structures. Selecting graphite crucibles for metal casting
