Waspaloy CR® round bar cold-reduced AMS 5708 (Type 1 is capable of AMS 5709) is a nickel-based alloy containing chromium and cobalt typically used in aircraft fasteners where high strength up to 1500° F and oxidation resistance up to 1750° F is required. Waspaloy CR® round bar is multiple melted, usually with either a vacuum induction melt (VIM) followed by a vacuum arc remelt (VAR), or a vacuum induction melt (VIM) followed by an electroslag remelt (ESR).
