Aluminum alloys exhibit different heat transfer characteristics when die cast versus gravity cast. To compensate for that difference Aluma Cast Foundry has developed a heat transfer chart to demonstrate the alloy options available in order to more accurately simulate the heat transfer characteristics the part will exhibit as a production cast part.

If heat transfer is an important issue for your cast part, it is vital that you raise the issue before proceeding with the prototype process.
