Benefits and Applications

Master alloy for the production of 925 ‰ sterling silver jewellery obtained by investment casting and torch casting. This alloy is the most popular alloy in China market due to its very decent white colour rendering the silver plating is just an option in production. The elements contained in this product ensure a high deoxidation after casting and a high surface quality, an enhanced tarnishing resistance, and excellent reusability, making it suitable for castings with and without stones in place. The alloy can be heat treatable to increase its hardness afterward.
