Description

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


Amdry MM509B-C and Amdry MM509B-F are chemically similar to MarM-509, but contain boron as a melt-depressant. These materials are 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.


The materials Amdry MM509B-C and Amdry MM509B-F of this product family differ primarily in their particle size distribution.
