1、Fast Cooling And Heating: This Casting Ingot Mold allows for fast cooling and heating, resulting in a better surface finish and better accurate for a refined melting effect. 2、Stable: The casting mould has good stability, does not break easily during heating, has good wear resistance, high lubricity, durability, high purity, high density and high mechanical strength. 3、Good Performance: Graphite Moulds for casting metal have good thermal stability, can withstand 2000 degrees Celsius, which shorten melting time, save energy to ensure reliable quality of products. 4、Suitable: For experiments and melting of colored metals such as gold and silver, brass, copper, aluminium and zinc, also for use as test and analysis tools and ingot moulds for bar or necklace pendant. 5、Graphite Material: The mould uses high pure graphite, which will not affect the purity of the metal during the refining process. Also is good impact resistance and resistance to acid and alkali corrosion. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-YJL official store
