Certal (EN AW 7022) data sheet
Certal is designed to combine the best mechanical properties with excellent workability and optimal dimensional stability.
 
This alloy was created to meet the mould manufacturers' demand for a material that would be capable of offering the uncompromising hardness and workability required for the construction of moulds and equipment.

The typical applications include moulds for thermoplastic blow and injection moulding.
