Benefits and Applications

Master alloy for the production of 925 ‰ sterling silver jewellery obtained by investment casting. The elements contained in this product ensure an extreme level of deoxidation after casting and a high surface quality, an enhanced tarnishing resistance, and excellent recyclability, making it suitable for castings with and without stones in place. The alloy can be heat treatable to increase its hardness afterward.
