Alcast is a 7021 T6 alloy that offers an excellent combination of superb mechanical properties and reduced residual stress.
Thanks to its high mechanical strength, excellent gloss, and dimensional stability during use and processing, Alcast is suitable for creating moulds for plastic materials, models, special technical moulds and structures for hydraulic applications, and various other types of general mechanical processing operations.
The casting technology and the high percentage of pure metal guarantee minimal porosity throughout the entire cross-section of the plate.
Alcast is particularly recommended for the following applications:
- Resin transfer moulding;
- Compression moulding;
- Resin injection moulding;
- Blow moulding;
- Thermoforming.
Alcast is not recommended for moulds with complex shapes and sharp corners. For these applications, we recommend using rolled products wherever possible.
