Heraeus supplies master alloys with various for different karatages. Special additives such as silicon and boron have been added resulting a more-user-friendly alloy. Our alloys are suitable for all kinds of productions such as rolling, vacuum assisted casting or centrifugal casting. Common casting problem such as oxidative porosity is reduced to minimal. Due to the alloys’ ultra-high oxidation resistance, the recycling time of the gold alloys can be lengthened. Besides the popular colours, we have more coloured alloys for your choices. If there is a necessity, we can specifically make a unique alloy for your production. The production can thus be streamlined with Heraeus’ alloys.
