Feature:1. Graphite Material: Graphite mold uses high grade graphite material, and the ingot mold will not affect the metal purity during the metal refining process.2. Thermal Stability: Graphite molds for casting metals have good thermal stability, can withstand 2000 degrees Celsius, and shorten the melting time.3. Good Hot and Cold Properties: Fast hot and cold conditions, good thermal stability, can be used to make test analysis tools and ingot molds for bars or necklace pendants.4. High Performance: Graphite ingot mold has good impact resistance and acid and alkali corrosion resistance, saves energy, and ensures reliability and quality.5. Wide Range of Application: The ingot mold has a wide range of applications, and is suitable for experiments and smelting of non ferrous metals such as gold, silver, brass, copper, aluminum, and zinc.Specification:Item Type: Graphite MoldMaterial: GraphiteSize:External Size: Approx. 57 x 37 x 20mm/2.24 x 1.46 x 0.79inInternal Size: Approx. 40 x 20 x 15mm/1.57 x 0.79 x 0.59inIntroduction: the Capacity is 10ml, the Capacity of Gold is 200g/7.1oz, and the Capacity of Silver is 100g/3.5oz.Package List:1 x Graphite MoldNote:Please allow some errors due to manual measurement.
