Description

ToughMet Alloy is Materion Performance Alloys’ solution to your severe service material problems. By application of our proprietary process to implement the EquaCast® Microstructure, tailored alloying additions and spinodal hardening technology, we have engineered ToughMet alloy to provide attributes beyond those typically found in a high-strength copper alloy.


  • Exceptional resistance to corrosion and cavitation
  • Outstanding lubricity and durability in demanding applications
  • Highly uniform composition in all product forms
  • Uniform microstructure in a variety of wrought shapes and sizes
  • Related Standards
