SilverAlloy A-38T Flux Coated
Nominal Chemical
Composition
INTRODUCTION
Aufhauser SilverAlloy A-38TFC is a cadmium-free filler metal with free-flowing characteristics. The brazing temperature range is similar to that of SilverAlloy Cd-30 and Cd-35, making it an ideal substitute for such cadmium-based filler metals. Aufhauser A-38TFC comes pre-fluxed with the correct amount of flux. No dipping or preparatory work needed.
APPLICATIONS
Aufhauser A-38TFC is used for joining most ferrous and non-ferrous metals.
