JOINING OF ALUMINUM ALLOYS 6009/6010

Aluminum is recommended as the best alternative to steel in making lighter and more fuel-efficient automobiles. The new Alcoa aluminum alloys 6009-T4 and 6010-T4 are discussed. These alloys have good formability in the as-received condition and superior strength and dent resistance in the aged (-T6) condition which can be achieved in paint bake cycles. The alloys are similar in composition and do not require scrap segregation. They also provide improved welding characteristics through a combination of better metallurgical characteristics and lower and more uniform surface resistance. The metallurgical factors and surface conditions which make these new alloys more effective are discussed, as well as applicable joining methods (spot welding, mechanical clinching, adhesive bonding, riveting, weldbonding, clinchbonding, and rivetbonding), procedures and the test results obtained.
