ToughMet Alloy Recognized In New Aerospace Materials Specifications

Mayfield Heights, OH – May 12, 2011—Two Aerospace Materials Specifications for ToughMet®3 AT110 Rod/Bar and AT110 Tube were approved by the AMS Committee D and published by SAE’s Aerospace Materials Division Council. These wrought spinodal alloy product forms now are approved for improved property combinations and/or increased size range. 

AMS 4596B and AMS 4598 for rod/bar and tube, respectively, are also listed in the Materials Properties Development & Standardization (MMPDS-05) Handbook.  This handbook, formerly known as the Department of Defense (DoD) MIL-HDBK-5, contains Federal Aviation Administration (FAA) approved “design allowables” for metals and alloys used in aerospace vehicles that require sanctioned specifications.

The ToughMet® family of Cu-Ni-Sn alloys exhibit high strength and excellent wear and corrosion resistance and are used in many demanding aerospace, chemical, and industrial applications.  ToughMet® 3 also has superior tribological characteristics and is a good choice for bearing and bushing designs in demanding applications such as in aircraft landing gear and airfoil controls where high strength and wear resistance is required.

AMS standards enable easy ordering of materials by aircraft manufacturers and reflect rigorous statistical evaluation of property limits, assuring that producers have reliable manufacturing processes.  In addition, these standards are fundamental to the qualification process for new materials by aircraft manufacturers and give assurance that the supply chain will provide proper material.

In addition to ToughMet®, Brush Performance Alloys’ copper-beryllium alloys are also recognized in the AMS system.
