KappTecZ™ KappTecZtm is a high temperature,
high strength solder that may be used on most metals, but especially
aluminum, copper and stainless. It has a high tolerance to vibration and
stress, and good elongation for use on dissimilar metals.
Uses
This general purpose silver alloy solder is used for ferrous and
non-ferrous joining where high strength is required at a comparatively low
temperature. KappTecZ will solder all solderable metals including aluminum
as well as aluminum to copper.
Characteristics
Above its liquidus of 600° F, this solder is extremely fluid and will
penetrate the closest joints. It is used with a flux appropriate for the
base metal, and its performance in application is similar to the more
expensive silver brazing alloys. The joints have good corrosion
resistance, high electrical properties, and high shear and tensile
strengths.
