  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 icon Tech Brief - Welding ToughMet

    Welding provides the highest strength bond when joining ToughMet to itself or to other metals. As with any joining process, properly prepared surfaces, selection of equipment and materials, and sound practice are key to insuring a reliable bond.

  2. PDF icon Tech Brief - A Guide to Galvanic Corrosion

    Galvanic can occur when two or more dissimilar metals contact each other in an electrolytic environment. This can occur in seawater, chemical processing, or in automotive fasteners and connectors exposed to road salt spray. It is important to understand the relative position of metals on the galvanic series when they will be coupled near an electrolytic solution.

  3. PDF icon Tech Brief - Designing and Working with Heavily Loaded Bushings made from ToughMet®

    Materion Performance Alloys produces a series of alloys under the name ToughMet. These spinodally hardened copper nickel tin alloys have proven success in thrust bearings, journal/plain/sleeve bearings, and linear sliding bearings. Following are a series of recommendations on recommended clearances, tolerances, interference fits, and machining practices, allowing you to get the most out of your bearing/bushing design.

  4. PDF icon Tech Brief - Anti-Friction Behavior Of Select Copper-Based Bearing Alloys

    In a representative test for coefficient of friction, Materion Performance Alloys ToughMet® family of alloys showed a favorable combination of high strength and low friction.

  5. PDF icon Tech Brief - Hardness Testing Of High Performance Copper Alloys

    Indention hardness tests are the most common procedures for evaluation of the mechanical properties of copper alloy components. The tests are inexpensive, quick, easily performed and require little test material. Hardness testing is used to monitor processing operations such as cold working, solution annealing, quenching, and age hardening.

  6. PDF icon Tech Brief- Cavitation Resistance Of Selected Copper Alloys

    Cavitation damage is caused by the repeated nucleation, growth and collapse of bubbles against a metal surface in a liquid. Materion Performance Alloys ToughMet® and copper beryllium products are highly resistant to cavitation.

  7. PDF icon Tech Brief - Enhancing ToughMet® 3 Bearing Performance with Metalife Hard Coated Steel

    In comparative sleeve bearing tests against a hardened steel shaft, ToughMet showed unprecedented performance for a metallic bearing material. ToughMet’s bearing properties can be further enhanced when coupled to steel that has been hard coated and polymer impregnated for improved performance.

  8. PDF icon Tech Brief - Galling Resistance Of ToughMet 2

    The exceptional galling resistance of ToughMet® 2 and other copper alloys for wear plate applications is explored in this technical paper.

  9. PDF icon Tech Brief - Machining Recommendations For ToughMet

    The machining recommendations (turning, milling, drilling, tapping, grinding and sawing) for ToughMet® 3 AT and CX tempers of rod, tube and plate alloys are discussed in this technical brief.

  10. PDF icon Tech Brief - Optimum Material Properties for Improved Bearing Performance

    Materion Performance Alloys’ ToughMet® family of copper-nickel-tin alloys is tailor-made for bearing applications. ToughMet possesses a unique combination of mechanical and physical properties that improve bearing performance.

  11. PDF icon ToughMet- Technical Briefs- Spinodal Decomposition of ToughMet

    This Technical Brief discusses the spinodal decomposition reaction that provides an exceptional combination of strength, hardness, wear resistance and lubricity to ToughMet® and moldMAX® XL alloys.

  12. PDF icon Tech Brief - ToughMet Plain Bearing Performance with High PV

    This technical brief demonstrates that ToughMet® plain PV limits can be significantly higher than other bearing alloys, including popular cast manganese and aluminum bronzes, particularly at heavy loads.

  13. PDF icon Tech Brief - ToughMet® Alloy with Solid Lubricant Inserts: A Maintenance-Free Option at Higher Speeds and Pressures

    Self-lubricating bearings are used when operating conditions make it desirable or necessary for a plain bearing to run without external lubrication. Inserting solid lubricant plugs into a metal bushing or wear plate is a common method for making self-lubricating components. If the component is properly fitted to the application, the interface will be maintenance free over a long lifetime.
