TOUGHMET TECHNICAL REVIEWS

Technical Reviews are detailed comparisons of Materion products to competitor materials. Below are the Technical Reviews on ToughMet which present a range of material properties and test data to highlight performance advantages of each.

  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.

TOUGHMET ALLOYS TECH BRIEFS 

  1. PDF icon Transverse Tensile Properties of ToughMet® 3 Alloy Rod

    A series of tensile tests were performed to determine transverse tensile properties of Materion’s ToughMet 3 rod products, 2.5” to 6.0” diameter rods of CX105, AT90, AT110, TS95, TS120U, TS130, and TS160U tempers. Each sample was tested according to ASTM-E8-16a to determine average transverse tensile strength, 0.2% offset yield strength, total % elongation.

  2. 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.

  3. 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.

  4. PDF Document Chemical Analysis at Materion Spectrometry Laboratories

    This paper describes the methods Materion uses in production of our high reliability alloys.

  5. PDF Document Galling Resistance of Alloy 25 and ToughMet 3 to Various Materials

    Galling occurs when metals adhere to each other during sliding contact. This is especially important when considering threaded connections

  6. PDF Document Temperature Dependence of Tensile Properties for Various Alloys

    The temperature dependence of the tensile properties for various tempers of ToughMet 3 (C72900), Alloy 25 (C17200) and Alloy 3 (C17510) rod were measured from -195 °C (-320 °F) to 345 °C (650 °F) in accordance with ASTM E21.

  7. 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.

  8. PDF icon 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.

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

    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.

  10. PDF icon 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.

  11. PDF icon 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.

  12. PDF icon 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.

  13. PDF icon 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.

  14. PDF icon Galling Resistance Of ToughMet 2 Alloy

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

  15. PDF icon Machining Recommendations For ToughMet Rod, Tube and Plate

    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.

  16. PDF icon 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.

  18. PDF icon 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.

  19. PDF icon 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.
