  1. PDF icon Technical Review - Analysis of ToughMet® 3 and Cu-14Ni-3Al (Metric)

  2. PDF icon Technical Review - Analysis of ToughMet® 3 and Cu-14Ni-3Al (Imperial)

    ToughMet 3 and Cu-14Ni-3Al are both high strength copper alloys commonly used in the marine and oil and gas industries, but significant differences are realized when their properties are compared. This Technical Review discusses those differences that make ToughMet an advantageous replacement for the nickel bronze alloy in demanding applications and severe environments.


  1. PDF Document Rotary Bending Fatigue for AT110 and TS Tempers of ToughMet 3 Alloy

    Materion conducted rotary fatigue testing (R=-1) on the TS95, TS120U, TS140, and TS 160U tempers of the ToughMet 3 alloy product line. All the tempers were tested locally in air at ambient temperature using an hour glass type coupon with single force loading meeting the guidelines of ISO 1143.

  2. PDF Document Charpy V Notch Behavior of ToughMet 3

    Materion tests the CVN impact strength of its materials in accordance with ASTM E-23 with a Type A specimen.
