Product Specifications


AM Cu-0 is pure copper primary used for brazing steel. AM Cu-0 is OFHC (Oxygen Free High Conductivity) and is the purest commercially available copper available. AM Cu-0 is used as an economic braze filler metal for brazing high-volume industrial and automotive components. AM Cu-0 produces ductile, hermetically sealed assemblies when brazed in an inert, controlled atmosphere brazing (CAB) furnace, or vacuum.


Brazing Characteristics 

AM Cu-0 brazes to stainless steel, carbon steel, nickel, metalized ceramics, and Tool Steel. A minimum brazing temperature of 2012° F (1100°C) is recommend.



AM Cu-0 is produced in accordance to American Welding Society (AWS) A5.8 Specifications. Copper Development Association: CDA 101, CDA 102, CDA 110 


Forms Available 

Wire, Foil, Atomized powder, Paste, Sheet, and Preformed shapes; rings, washers, discs, shims, specialty shapes. Two dimensional shapes can be Laser-cut and machined with EDM though parts must be cleaned prior to brazing.
