It is important to understand the relative position of metals on the galvanic series when they will be coupled near an electrolytic solution. 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. Tech Brief - Heat Treating Copper Beryllium Unlike many other copper base alloys which acquire their strength through cold work alone, wrought copper beryllium obtains its high strength, conductivity, and hardness through a combination of cold work and a thermal process called age hardening.

Tech Brief - Surface Coating High Performance Copper Alloy Strip In order for electrical contacts to function properly, it is necessary to keep the total resistance of the contact interface low. The choice of a correct coating can mean the difference between a good electrical contact (signal transmission) and a failed connection. Tech Brief - Tensile Testing High Performance Alloy Products The mechanical properties of Materion Performance Alloy wrought products are most frequently measured by the simple uniaxial tensile test. The test itself is relatively simple, but interpretation and use of the test data for these alloys require a thorough understanding of both the test procedure and the alloy’s behavior during testing Tech Brief - Welding Copper Beryllium Welding provides the highest strength bond when joining copper beryllium 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.
