High Performance Platinum Alloys for Jewellery Manufacturing
PLATINA® is a family of 950‰ platinum alloys developed for jewellery manufacturing through investment casting and plastic deformation processes. Engineered to deliver high hardness, excellent wear resistance and reliable production behaviour, PLATINA® improves the long-term durability and quality of platinum jewellery. Designed to overcome the traditional limitations of platinum alloys, PLATINA® combines mechanical strength, process reliability and excellent production behaviour.
Engineered for Durable Platinum Jewellery Production
PLATINA® is designed to enhance the mechanical and technological performance of platinum jewellery while maintaining reliable manufacturing behaviour. Its formulations are specifically engineered to improve hardness and wear resistance, two essential characteristics for long-lasting platinum pieces. Selected alloys within the family also benefit from a lower melting range compared to conventional platinum alloys. This characteristic supports improved form-filling capacity, more stable casting behaviour and reduced thermal stress during production. In addition, PLATINA® combines metallurgical performance with production efficiency. The controlled density of specific compositions allows manufacturers to optimise precious metal usage while maintaining the same design volume and structural integrity. The result is a platinum alloy family capable of combining durability, process reliability and more efficient material management.
