INDUSTRY ADVISORY 62014

SUBJECT: 7000 ALLOY ALUMINUM

Aluminum bumper reinforcements are made from both 6000 and 7000 alloy aluminum depending on model and application. You have choices for aftermarket aluminum rebars.

It’s critical to note that only Diamond Standard Brand produces and properly heat treats and artificially ages 7000 high strength Alloy Aluminum.

Substitution of 6000 Alloy mild strength aluminum is not only weaker by 40% but also fails in quasi-static tests below factory by 20-25% on average. These are not marketing claims but rather Aluminum Industry published facts.

To be certain you are informed, we have included a list of 6000 and 7000 alloy aluminum reinforcements by part number and description.

Diamond Standard’s policy on replacement of Structural Bumper Components including high strength and mild strength aluminum reinforcements is Diamond Standard or OE only.

Sincerely,

Michael O’Neal
President
Diamond Standard Brand Parts Group
