Incoloy A-286 Hexagon Bar

Product Details

An alloy that is precipitation hardenable for high mechanical properties. The alloy maintains good strength and oxidation resistance at temperatures up to about 1300˚F (700˚C). The alloy's high strength and excellent fabrication characteristics make it useful for various components of aircraft and industrial gas turbines. Applications include blades, vanes, shafts, tail cones, afterburners, springs and fasteners. This alloy is also used for automotive applications.

STANDARD PRODUCT FORMS
Sheet, strip, plate, round bar, flat bar, forging stock,hexagon and wire.
