Forged thick blocks in Alumold® 500 have been developed to provide high and consistent strength across the thickness, good dimensional stabilityand excellent machinability, in order torespond to the high requirements of the applications in plastics transformation. Typical applications include compression or injection moulds for plastics.
Alumold® 500 forged blocks are produced in an alloy of the 7000 series.

Heating the alloy can result in loss of strength of properties or of capability for fabrication, assembly or application in a particular case. Whenever a new application of this alloy is contemplated, and if this application involves special properties such as corrosion resistance, toughness, fatigue strength, it is strongly recommended that the user should consult the producer in order to make a precise and appropriate selection of the material.
The information in this publication does not imply a guarantee of properties or of capability for fabrication, assembly or application in a particular case. The appendix to technical datasheets is an integral part of this datasheet. The processing instructions presented in the appendix shall be taken into account by the user.
