hPt range of products is specifically studied for the production of platinum jewellery. hPt can be used in investment casting and plastic deformation as well. The main feature of this master alloy is the hardening capacity. The elements in the composition, moreover, decrease the melting range of the platinum alloy, making low temperature castings possible, having so a better surface quality and a lower consumables deterioration. Also in mechanical working, hPt products’ low melting range allows to use lower casting and annealing temperatures, making its use easier and more stable.
