Permanent mold cast lead-free copper-base alloys provide foundries with a wealth of new casting markets to pursue. In comparison to their sand cast counterparts permanent mold cast copper base alloys offer improved design and process parameters to the foundry and customer, providing them flexibility in their alloy choice.The problem, however, is that these improved parameters have never been documented. In addition, with lead-free copper-base alloys emerging as a possible material choice for customers, the lack of process and design parameters becomes an even bigger issue.
