PLAST693R
Master alloy for the production of red 375 – 417 – 585 – 750 – 917 ‰ gold jewellery obtained by mechanical working. The elements contained in this product ensure a high surface quality and 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 0 – 20 % of pure silver to the master alloy.
