It is believed that the following points can be used as guidelines in transducer material selection. 1. No metal will provide a guarantee against corrosion failure. Selection must be made on the function and criticalness of the part and compatibility to all neighboring parts. Cost to the customer can be a major consideration. 2. One metal is better than two. Avoid dissimilar metals if possible reduce joints and fittings to a minimum. 3. Cover metallic surfaces where possible, especially when using the lower grade materials. Full covering is greatly to be preferred over partial or broken covering. 4. Mounting and environmental conditions are equally as important as the selection of materials. Specifically watch adjoining materials, electrolytic action, and the question of grounding. 5. Wherever possible, make tests simulating the actual conditions. Accelerated life tests are helpful, but usually do not evaluate all conditions likely to be encountered.
