1. Tech Brief NACE MR0175/ISO 15156 Compliance of ToughMet and Copper Beryllium

   The purpose of the NACE MR0175/ISO 15156 standard is to provide a set of guidelines for the use of material in sour (H2S) service.  Copper alloys in general (including copper beryllium and ToughMet 3 copper nickel tin) are listed in the standard as being acceptable for use in sour service.  Data that show how copper beryllium and ToughMet withstand severe enviroments are shown in this paper.

2. 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. Tech Brief - Designing and Working with Heavily Loaded Bushings made from ToughMet®

   Materion Brush 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. Tech Brief - Anti-Friction Behavior Of Select Copper-Based Bearing Alloys

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

5. 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. 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 Brush Performance Alloys ToughMet® and copper beryllium products are highly resistant to cavitation.

7. Tech Brief- Chloride Stress Corrosion Cracking Resistance of High Performance Copper Alloys

   This technical brief discusses the excellent resistance of copper beryllium and ToughMet to the catastrophic failure mode of stress corrosion cracking (SCC).

8. 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.

9. 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.

10. 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.
