Alloy W is a solid solution strengthened nickel superalloy developed primarily as a filler metal for welding dissimilar alloys. Alloy W has excellent dissimilar welding characteristics, and is widely used for that purpose in the gas turbine, aerospace and chemical process industries. The properties of dissimilar weld joints made with alloy W are dependent upon the base metal being joined, but are generally acceptable for a wide range of combinations.
