1. Tool Steel (e.g., P20, H13): P20 and H13 are popular choices for general-purpose molds and can withstand the demands of high-production runs.

2. Stainless Steel (e.g., 420, 440): They are often used in food packaging, medical devices, and other industries where cleanliness and durability are crucial.

3. Aluminum: They are commonly used for prototyping, low-volume production, or for parts that do not require high production volumes.

4. Beryllium Copper: They are suitable for applications where high thermal conductivity is required, such as in molding high-performance plastics.

5. Prehardened Steel (e.g., 4140): They are often used for lower-production runs or molds that require moderate hardness and wear resistance.
