Oxford Alloy #6 Coated is a non-ferrous, cobalt-chromium-tungsten alloy. This electrode is recommended for metal-to-metal abrasion and high impact applications involving high temperatures and/or corrosive media. Some typical applications are valves of all kinds, shear blades, hot punches and saw guides. Oxford Alloy #6 Coated is the most generally useful cobalt alloy; it has excellent resistance to many forms of mechani-cal and chemical degradation over a wide temperature range. This alloy has outstanding self-mated anti-galling properties, high temperature hardness, and a high resistance to cavitation erosion, which result in its wide use as a valve seat material. It is ideally suited for a variety of hard-facing processes. The weld deposits of the Oxford Alloy #6 Coated are smooth and normally acquire mirror-like finish in use. The deposits retain wear resistance at high temperatures. This alloy is nonmagnetic and is not forgeable. It can be machined with carbide tools. Oxford Alloy #6 Coated bonds well with weldable alloy steels, including stainless.
