| * The mechanical properties shown in the table above are intended as guidelines. However, since the properties may vary with the location of a given casting, the suitability of a particular metal for a specific use is best determined by laboratory or service tests. Mechanical properties will vary in terms of microstructure, which especially in as-cast conditions, is dependant on section size, chemical composition and foundry processes. ** Palmer Assoc. can supply castings compliant with specifications such as ASTM, SAE, DIN or other equivalent international requirements.
