Description

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


Amdry MM509 and Amdry MM509-C are the chemically equivalent powdered form of superalloy MarM-509. These materials are used as superalloy matrix material when blended with boron-containing braze filler metals for activated diffusion brazing applications.


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 MM509 and Amdry MM509-C of this product family differ primarily in their particle size distribution.
