What is the benefit of 7000 series aluminum?

7000 Aluminum reduces the overall weight of the chair by 2 lb., making it comparable in weight with titanium frames. The big advantage of 7000 aluminum is three-fold.  One, the material is approximately 23% stronger than 6061 aluminum. Two, since the material is stronger, we are able to reduce the wall thickness of the aluminum tubes, reducing the overall weight.  Best of all, the rigidity and strength of a 7000 aluminum frame is further enhanced by Invacare Top End’s sophisticated heat treating and powder coating process.
