Certal® is an aluminium that offers a combination of excellent machinability, dimensional stability and high resistance. This makes this alloy an ideal choice in the production of industrial tools, including blow moulds and injection moulds that are used to create plastic bottles and containers. Certal® can also be used in the production of heating plates, mechanical guides, tool holders, jigs and accessories.
