Amdry MM509B-C is a cobalt-based braze filler metal designed for activated diffusion brazing. It has a composition that is chemically similar to MarM-509. This braze alloy has a coarser size distribution than Amdry MM509B-F. It can be blended with activated diffusion braze alloys to facilitate crack repair and restoration. It can also be blended with standard braze alloys to facilite wide-gap brazing. It is supplied as a powder but can be supplied as a paste or customized tape on request.
