OFHC Copper CDA 101
INTRODUCTION
Aufhauser's Oxygen Free High Conductivity Copper CDA 101 is a filler metal used in the brazing of ferrous and nickel-based alloys. Applicable for brazing steel, stainless steel, and copper-nickel alloys. Best results are produced in a vacuum furnace without the use of flux.
BRAZING CHARACTERISTICS
OFHC flows freely with good wetting characteristics on ferrous and nickel-based materials. Optimum strength and joint integrity are achieved when joint clearance lies between 0.000 in. - 0.001 in. (0.000 - 0.025 mm) per side.
