High quality graphite crucible for aluminum copper metal refining and melting
Characteristics of our graphite mold:
1. Graphite molds are one of the most heat-resistant materials at present.
2. With good thermal shock resistance, no cracks will occur when the temperature is hot and cold
3. Excellent thermal conductivity and conductive properties
4. Good lubrication and abrasion resistance
5. Chemical stability, acid and alkali resistance and corrosion resistance, not easy to react with most metals
6. Factory supply customized graphite sintering mold Easy to process, good mechanical processing performance, can machining complex shape and high precision mold
