SilverAlloy A-56T Flux Coated


INTRODUCTION

SilverAlloy A-56TFC is a cadmium-free, low melting alloy suitable for use on steel, stainless steel, copper, copper alloys, nickel, nickel alloys or a combination of them. A-56TFC is pre-fluxed with the correct amount of flux. No dipping or preparatory work necessary. It is suitable for work in tight spaces. Its whitish color provides good color match where necessary.

APPLICATIONS

Aufhauser A-56TFC is used for joining most ferrous and nonferrous metals. A-56TFC has good brazing properties and is suitable either for pre-placement in the joint or for manual feeding into the joint. Although lap joints generally are used, butt joints may be used if requirements are less stringent. Joint clearances of 0.001 to 0.005 in. (0.025 to 0.127 mm) are recommended for proper capillary action. A-56TFC is also used for brazing stainless steel, nickel or nickel alloys where stress cracking occurs during the brazing process.
