Joining techniques

Welding

The high conductivity and reflectivity of traditional sterling silver makes the alloy difficult to weld. The

small amount of germanium in Argentium 960-Pure increases the thermal and electrical resistance,

making the silver suitable for welding processes.

Advantages of welding

Welding applications offer efficient production methods, using localised heat for joining materials.

Welding technologies provide excellent alternatives to the use of solders.

The weldability of Argentium Original opens new avenues for the design and production of silverware

and jewellery items.

Measuring conductivity

The International Annealed Copper Scale (IACS) is a measure of conductivity in metals and alloys (lower

IACS values = increased weldability).

The chart below shows the IACS values for various metals and alloys.
