Metco 5640NS is a nickel-chromium powder that can be blended with a standard or activated diffusion braze filler metal for wide-gap brazing applications. The nickel-chromium composition offers particularly good corrosion resistance and may be chosen over other wide-gap filler materials when corrosion is a concern. Metco 5640NS does not melt during the braze process but acts as a matrix that helps the braze filler metal span the joint.
