Solders and solder pastes for jewellery, watches and decorative applications

Soldering is one of the most important techniques used by goldsmiths when creating a permanent connection between individual parts of a piece of jewellery. C.HAFNER offers a wide range of coloured gold, white gold, platinum, palladium and silver solders for a wide variety of applications. The most important details of our sheet and wire solders can be found in the following table.

In addition, solder pastes complement the C.HAFNER precious metal products. HILDERBRAND solder pastes are a homogeneous mixture of solder powder, a binder and – depending on the application – a flux. The pastes are characterised by their outstanding quality, swift, precise application and exact dosability in conjunction with low solder consumption levels. They are available in all standard finenesses and colours as well as in many different working temperatures.
