Amdry™ nickel and cobalt superalloy powders were developed as complimentary additives for Metco ADB (Activated Diffusion Braze) filler metals, such as Amdry DF-3, DF-4B, DF-6A or BRB, for crack repair and surface restoration. These superalloy products are produced by a dry gas atomization process to assure consistency, purity and conformity to rigid industrial, aerospace and military specifications.

Regardless of the base material that required brazing or repair, the wide range of Metco superalloy powders ensures the right choice and availability.

Metco superalloy products are produced and available as powders. While blending is typically performed by the customer, any ratios desired can be pre-blended for you by Oerlikon Metco. The powders can be delivered pre-blended with braze alloy powders for use with cements or gels. The blends can also be converted to paste, braze tape or braze preforms for a more precise and cost-effective method of application.

Amdry superalloy products do not contain temperature suppressants. Therefore, they are designed not to melt during the braze process, but to form a matrix within the braze joint that is metallurgically compatible with the substrate material.
