Nickel Alloy 625 per DMS 1979
DMS 1979 or DMS1979 specifies requirements for tubing made from Nickel Alloy 625 (UNS N06625) to be used in aircraft hydraulic systems, fuel systems, and environmental control systems, with specified chemical makeup and performance requirements for manufacturing of tubing and performance requirements for thin-wall tubing used in the aircraft industry.
The Nickel Alloy 625 is a mix of nickel, chromium, molybdenum, and niobium that results in the production of a nickel alloy with high mechanical characteristics, resistance to oxidation, and immunity to pitting. The Nickel Alloy 625 also retains its ductility and flexibility at high temperatures and is often used for aerospace industry applications because of these characteristics.
DMS specifications originate from Boeing’s Long Beach facility under D1-4426 Approved Process Lists.
