(4) The influence of shell-making materials: zircon sand, zircon powder, Shangdian sand, and Shangdian powder are used. Because of their small expansion coefficient, only 4.6×10-6/℃, they can be ignored.

3. Durability and Corrosion Resistance Another key benefit of copper is its resistance to corrosion, especially when alloyed with other metals. This makes copper stamped parts suitable for environments exposed to moisture or chemicals. Their durability ensures that they retain their integrity over time, reducing the need for frequent replacements.
