Software Takes Guesswork Out Of Alloy Selection

The North American Die Casting Association (NADCA) has created a software package to help designers, product specifiers and die casters identify the aluminum alloy chemistry needed to meet a specific set of casting properties. Developed in conjunction with Worchester Polytechnic Institute, i-Select Al allows users to select an alloy from a comprehensive database of aluminum die casting alloy chemistries and properties covered by more than 300 worldwide standards. Users can either input desired properties to create alloy chemistry or input alloy chemistry to predict properties.

 

To modify aluminum alloy, users can change the percentages of 10 elements that are used in addition to aluminum to create casting alloys. Different combinations can change characteristics such as density, thermal conductivity, ultimate tensile strength, tensile yield strength, ductility and elasticity. In addition to the property database, the program includes casting characteristics, photomicrographs of representative microstructures, stress-strain curves, fatigue curves and cooling curves of various aluminum alloys.
