Corrosion Considerations In The Selection of Materials In Automotive Terminal Systems

The corrosion performance of alloys considered suitable for automotive terminal systems are examined. General corrosion is insignificant when copper alloys are used. The designer can avoid stress corrosion by choosing from a complete range of mechanical and electrical property combinations in less sensitive and even immune copper alloys. Crevice corrosion can be minimized chiefly by designing to eliminate crevices and also by choice of less susceptible alloys. Finally, dezincification can be overcome by using less susceptible modified brasses or inhibited brasses; lower zinc alloys or alloys not containing zinc may also be used.
