The Quest for Quality: Optimising Platinum Casting for 21st Century Needs
There is much interest in developing new casting alloys and techniques for platinum. Despite numerous advances in casting equipment and technology, there are still many areas to improve upon which can reduce production costs and result in a sturdier product. This review examines
the casting behaviours of 900 and 950 platinum alloys with additions to increase the hardness. The main aim of this study was to discover the solidification patterns of platinum alloys from molten to the solid state, with characteristics assessed including shrinkage porosity, gas porosity
and form filling. In addition, alloy hardness levels and the effects of thermal post-processing of castings were explored.
