PlatinGold offers the benefits of a fine crystalline structure even after casting. Highly reactive elements such as tungsten and gallium have been avoided. This makes the material ideal for polishing and gives it good soldering and welding properties. In addition, its low melting range makes it easier to cast. The optimised grain structure and good malleability make it reliable to work with, providing plenty of scope for the creative manufacturing process.
Both handcrafting using conventional goldsmith’s techniques and machining on lathes or milling machines are much easier. PlatinGold makes processing a great deal more efficient.
