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

    This material data has been provided by Materion Brush GmbH.

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
