STAR651L

Universal master alloy for the production of white nickel and palladium free 375 – 417 – 585 ‰ gold jewellery obtained by investment casting and mechanical working. The elements contained in this product ensure a high surface quality in investment casting, while in mechanical working a high deformation capability thanks the small grain structure, making it suitable for the production of hand and machine made hollow and solid chains, deep drawn items and tube. The use is suggested with the addition of 80 – 90 % of pure silver to the master alloy.
