Alumold-350® has been specifically developed to achieve the best combination of strength at low and high temperatures, together with a good shape stability and machinability. Alumold-350® is particularly suitable for plastic forming machinery operating at temperatures up to 200°C, which is the temperature for moulding of rubber and other elastomers.
Alumold-350® is based on alloy of the 2000 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. This edition replaces all previous editions.
