The Aluminum Line
While making body and chassis components out of aluminum to achieve lightweighting gets lots of attention, weight savings anywhere in a vehicle is generally advantageous.
As in brake lines.
Sapa Extrusions, Inc. (sapagroup.com), a Norwegian company that specializes in making things with aluminum, has developed what it says is the first-ever, high-strength aluminum automotive brake line.
Sapa innovation and technology manager, Jens Sandahl Sorensen, claims the aluminum brake line is about 50 percent lighter than a comparable steel line.
Realize that there is from 39 to 40 feet (12 to 14 meters) of brake line in a conventional light vehicle. This weighs about 2.2 pounds (1 kg). With the aluminum approach, about 1.3 pounds (600 grams) of mass can be saved.
The aluminum brake line has undergone several tests for potential OEM application including those for vibration, burst, toque, leak, coating adhesion and corrosion.
