Abstract
Described is a material handling apparatus for processing heated formed ferrous metal products and/or glass products comprising a face centered cubic crystal intermetallic alloy of a metal aluminide having the property of withstanding repeated thermal cycling from ambient temperature to about 1600.degree. F. wherein the metal is selected from the group consisting of a group VIII metal of the Periodic Table. Also described is an aluminide roll that also is characterized as retaining its ultimate tensile strength at 1600.degree. F. of at least 75% of the tensile strength the roll had at ambient room temperature.

A material handling apparatus for processing heated formed ferrous metal products and/or hot glass products, comprising:
- a cast metal apparatus having an as-cast structure consisting essentially of
- a face centered cubic intermetallic single phase of metal aluminide and having the property of retaining at least 75% of its ultimate tensile strength as measured at room temperature when heated to about 1600.degree. F. wherein the metal of the metal aluminide consists essentially of nickel, aluminum and chromium, wherein the nickel ranges from 74-87.3 weight percent;
- chromium is present in an amount from about 6 to 10% by weight and aluminum is present in an amount of 6 to 14 percent by weight.
A roll useful for transferring heated formed ferrous metal products and/or glass products comprising a cast metal roll having an as-cast structure consisting essentially of a face centered cubic intermetallic single phase of metal aluminide and having the property of retaining its ultimate tensile strength at 1600.degree. F. of at least 75% of its tensile strength at ambient room temperature wherein the metal of the metal aluminide consists essentially of nickel, aluminum and chromium, wherein the nickel ranges from 74-87.3 weight percent;
- chromium is present in an amount from about 6 to 10% by weight and aluminum is present in amount of 6 to 14 percent by weight.
