Materials
A brief summary of the most commonly used alloys is shown for your guidance.
ZINC
Usually used for high-pressure (hot chamber) die casting.With careful design this material and process can combine to give a very fast production process with complex shaped components.
LM4
Usually used for gravity castings.Examples of components would be, general engineering, gearboxes, switchgear boxes etc. Can be heat-treated to improve mechanical properties.
LM6
Used for more intricate castings,meter cases,marine castings etc. Good corrosion resistance and ductility. Can be used for pressure or gravity casting.
LM24
Used for pressure die-casting. Suitable for most general engineering purposes.Can be machined easily and used for more intricate pressure die-castings.
LM25
A gravity die casting alloy.Has good mechanical properties which can be further improved by the use of heat treatment.This alloy is used where strength,soundness of casting and corrosion resistance are required.
ZA27
A special purpose zinc/aluminium alloy that has good bearing properties.
