Alloy C263 Sheet & Plate - Nimonic 263 - AMS 5872
Alloy C263 plate - Nimonic 263® is an age-hardenable nickel-cobalt chromium-molybdenum alloy designed specifically to combine good, aged strength properties with excellent fabrication characteristics in the annealed condition. While its strength at elevated temperatures is not quite as high as Waspaloy® or Rene 41, it is far easier to form or weld than these alloys. This grade is typically used for applications up to about 1650°F (900°C). This grade combines properties which make it suitable for a variety of fabricated components in both aircraft turbine engine and land-based turbine applications.

Characteristics of C263
Alloy C263 is non-magnetic, has high strength up to 1500°F (816°C) and good oxidation resistance up to 1800°F (982°C). This material exhibits excellent intermediate temperature tensile ductility. It is not normally subject to strain age cracking problems common for other gamma prime strengthened alloys.
Working with C263
C263 plate has excellent welding characteristics and can be welded by most customary techniques, such as inert gas tungsten arc (TIG), gas metal arc welding (GMAW), electron beam and resistance welding. Oxyacetylene and submerged arc processes are not recommended. Avoid excessive heat input when welding and when a filler metal is required a matching C-263 filler metal should be used. This grade is typically used in the fully aged condition. Following forming and welding, a full solution anneal prior to aging is often employed to develop optimum properties.
