The strongest wheels
Why is forged aluminium so strong ?
Forging aligns the grain structure of aluminium with the
shape of the wheel. This produces wheels with unrivalled strength that pass the
most demanding tests. TÜV, JWL- T, LBF tested and a five-year warranty without
any limitations on mileage.
High strength test results The
forged Alcoa wheel (above right) withstands a load of 71,200 kg before it
deforms by 5 cm. The rim of the steel wheel is deformed this much at only 13,600
kg. In other words, the Alcoa wheel is more than five times as strong!
Impact test results The Japanese JWL test
simulates a truck hitting a high kerb at a speed of 50 km/h. A 910 kg weight is
dropped onto the tyre and wheel assembly. The test is performed in the Alcoa
technical centre in Pittsburgh according to the Japanese CHIGI-15I-15III
specifications. While steel wheels show excessive deformation and cast aluminium
breaks, the Alcoa wheels pass the tests successfully.
