What Alloy Do You Choose?
The selection of an alloy must be based on a number of criteria,
based on design, economics and most importantly been able to use the chosen casting
method.
Pressure Tightness
Various alloys are suitable for castings that are required to be
leak tight and can be manufactured by the three methods of production offered by
Alucast Limited.
Machineability
Aluminium alloys can be machined faster and easily than many other
engineering materials as long as the machining conditions are selected to suit the
characteristics of the various alloys.
Mechanical Properties
Most castings are used in the as cast condition but in certain
applications that require higher mechanical properties, these properties in some
alloys can be improved by the use of heat treatment. High Pressure diecastings are
not normally heat treated.
