KappTEC™ KappTEC™ is a high temperature,
high-strength solder. It is used in applications where alloys melting
higher than soft solders are required, but the cost and strength of
silver-brazing alloys is not necessary.
This alloy is outstanding in high-vibration and high-stress situations.
Its high electrical conductivity verses other solders makes it an
excellent choice for electrical applications.
Uses
This is a general purpose solder that will join all solderable metals
except aluminum. It is highly recommended for stainless steel and copper
soldering.
Characteristics
Above its liquidus of 640°F (338°C), 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.
