Casting Alloy Information

Please find some helpful technical information for our casting alloys below. 

More than 90 years of experience manufacturing precious metal products ensures Morris and Watson offer the largest variety of raw, semi-finished and finished products in Australasia.

All casting metal alloys are developed and perfected by inhouse chemists and production experts to ensure the quality of fabricated materials is maintained.

Owing to the onsite refinery and Morris and Watson’s continued commitment to maintaining positive environmental practices, the majority of precious metals used to produce fabricated products have been recovered by refining recycled metal.

All batches are assayed for complete confidence.
