Alloys for jewellery, watches and decorative applications

The C.HAFNER alloy range stands for a multitude of alloys and excellent processing and finishing properties. The alloys listed below are only a small selection of our range. We are happy to advise you on the most suitable alloy for your application.

The following details were put together with great care and checked for accuracy. However, no liability can be accepted for any incorrect or incomplete information. As the alloys are continually developed further, the alloy range and alloy design are subject to change.

The matching solders and solder pastes for our stock items can be found in our stock programme or via our shop for semi-finished products.
