Description

The Amdry™ MM509 series of alloy powders are spherical, inert gas atomized, cobalt-based powders.


Amdry MM509B-C is chemically similar to MarM-509, but contains boron as a melt-depressant. It is commonly used as activated diffusion braze alloy for the repair of cobalt-based components. The Amdry™ MM509 series can also be used in thermal spray coating applications.


Gas atomization ensures excellent chemical homogeneity and high purity for consistent processing results.
