Australian-Made Master Alloys

Our master alloys are carefully formulated, granulated, micro-polished, XRF scanned and tested in-house at our Sydney facility before being released for sale.

Developed specifically for casters and jewellers who demand premium Australian-made alloys, reliable casting performance and consistent results from batch to batch.

Developed in collaboration with experienced master bench jewellers, our formulations are designed to perform not only in the casting process, but also throughout the bench. The resulting alloys provide the strength, density and workability required by demanding jewellers, while maintaining excellent casting characteristics.
