Nickel Alloy 625 per BMS 7-416
BMS 7-416 is a Boeing specification that addresses Nickel Alloy 625 Ring Forgings used in aircraft propulsion devices and structures. It covers requirements to ensure quality, traceability, and reliable mechanical performance. Nickel 625, also known as UNS N06625, is a nickel-chromium-molybdenum-niobium alloy that exhibits excellent oxidation resistance combined with high strength and resistance to corrosion at a wide range of temperatures.
The chemistry of the alloy, particularly the cooperative action of niobium and molybdenum, provides high matrix strength without requiring heat treatments. It is thus applicable for precision forgings that have to perform through cyclic exposures and thermal conditions without losing integrity.
Fighter Jet Metals works with Aerospace OEMs to maintain the BMS7-416 specification for Nickel 625 Forged Rings. If you are currently managing a project that requires BMS7-416 please reach out to us so we can assist.
Boeing Quality per BMS 7-416
BMS stands for “Boeing Material Specification” and originate from Boeing’s headquarters in Seattle, WA. For more information on BMS7-416 please refer to D1-4426 Approved Process Lists . As a Tier 1 Aerospace company, Boeing holds its subcontractors to the same standards by ensuring they source BMS7-416 from approved sources. This creates accountability and ensures the highest quality standards are achieved in the manufacturing process. An excerpt from Boeing’s quality website states the following:
Our commitment to steady, long-term improvement in our products and processes is the cornerstone of our business strategy. Maintaining customer satisfaction and enhancing shareholder value are mutual goals of both Boeing and its suppliers. To achieve these objectives, we must continuously work together to improve the overall efficiency and productivity of our design, manufacturing, administrative and support organizations.
