BMS7-246
BMS7-246 is a Boeing material specification for Ti-6Al-2Sn-4Zr-2Mo alloy, a titanium alloy in sheet, strip, and plate products for use in aerospace applications. This specification establishes the requirements for the composition, mechanical properties, processing, and quality control for the alloy.
Applications of BMS7-246 Titanium
Titanium produced to the BMS7-246 specification is commonly used in aerospace components where light weight, structural strength, and fatigue resistance are required.
Typical applications include:
- Aircraft Structural Panels – fuselage and wing structural sheet components
- Engine and High-Temperature Structures – panels and structural elements near turbine systems
- Aerospace Fabricated Parts – formed or machined sheet and plate components used in aircraft assemblies
Boeing Quality Requirements
BMS stands for “Boeing Material Specification” and originate from Boeing’s headquarters in Seattle, WA. For more information on BMS7-246 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 BMS7-246 from approved sources. This creates accountability and ensures the highest quality standards are achieved in the manufacturing process.
