Full title and description

SAE AMS 5966D (2024): Nickel alloy, corrosion- and heat-resistant, welding wire — nominal composition 50Ni‑20Cr‑20Co‑5.9Mo‑2.2Ti‑0.45Al (Alloy 263). Covers consumable electrode or vacuum induction melted and remelted welding wire form of Alloy 263 intended for corrosion- and heat‑resistant welding applications.

Abstract

This AMS material specification defines requirements, chemical composition, and product form (welding wire) for a Nimonic/Alloy 263 nickel‑base filler metal used where elevated temperature strength and corrosion/oxidation resistance are required. The document replaces the previous C revision and clarifies manufacture and acceptance requirements for consumable electrode or VIM/VAR remelted wire.

Scope

Specifies chemical composition, product form and identification, manufacture (consumable electrode or vacuum induction melted/remelted wire), and acceptance requirements for a corrosion‑ and heat‑resistant nickel alloy welding wire (Alloy 263 / Nimonic 263). Intended for use as a filler metal for welding or surfacing where resistance to high temperature and oxidation is required.

Key topics and requirements

• Designation and nominal chemical composition: ~50% Ni, ~20% Cr, ~20% Co, ~5.9% Mo, ~2.2% Ti, ~0.45% Al (Alloy 263 composition range specified in the standard).
• Product form: welding wire — consumable electrode or VIM/VAR remelted wire.
• Manufacture and melting practice requirements (controls for melting, remelting and cleanliness appropriate for aerospace filler metals).
• Identification, marking and traceability for batch/lot control.
• Mechanical and acceptance criteria appropriate for welding consumables used in high‑temperature service (chemical analysis and product inspection requirements).

Typical use and users

Used by aerospace and power‑generation manufacturers, welding consumable suppliers, subcontractors and repair shops that weld or fabricate high‑temperature nickel‑base components (turbine blades, discs, hot‑section components, and welded assemblies requiring high creep/oxidation resistance). Typical users include material engineers, welding engineers, procurement/specification staff, and quality/inspection teams in aerospace and gas‑turbine supply chains.
