Features
1. High thermal conductivity
2. High corrosion resistance, especially suitable for polyoxyethylene (PVC) products mold.
3. High hardness, wear resistance and toughness, as inserts used with mould steel and aluminium can make the mold play a highly efficient, prolong the service life.
4. Polishing performance is good, can achieve high mirror surface precision and complicated shape design.
5. Good tackiness resistance, easy to welding with other metal, easy to machining, there is no need additional heat treatment.
