1, high hardness: the die material needs to have enough hardness to ensure that it will not be deformed or worn during stamping.

2. Wear resistance: Die materials need to have enough wear resistance to ensure good stamping effect after long-term use.

3. Corrosion resistance: Because corrosive substances such as electrolyte will be involved in the stamping process of lithium battery tabs, the mold material needs to have sufficient corrosion resistance.

4. High strength: the die material needs to have enough strength to ensure that it will not break or deform during stamping.

5. Good thermal conductivity: the mold material needs to have good thermal conductivity to ensure rapid heat dissipation during stamping and avoid deformation or damage due to overheating.
