Features: High-quality graphite ingot molds can be used as graphite crucibles for smelting non-ferrous metals, testing and analysis, ingot molds, etc., to meet your DIY smelting, casting or refining metal needs. Advantages: These graphite casting molds have many advantages, such as good thermal stability, strong acid and alkali corrosion resistance, fast cooling, and good thermal conductivity, which can greatly shorten the casting for time and save energy. Reliable material: The main material is graphite, and the ash content is less than 0.1 percent , which ensures that the metal purity will not be affected during metal refining it has good thermal stability under cold and hot use conditions, and has better refining effect than silicon carbide graphite crucibles. Wide range of applications: ingot molds can be used for experiments and smelting of non-ferrous metals such as gold, silver, copper, aluminum, lead, etc. they can also be used as graphite crucibles for smelting non-ferrous metals, test analysis, and ingot molds considering the The size of the product is more suitable for small-capacity metal smelting. Lightweight Size: Portable and small size, easy to store and carry, bring you convenience.
