High strength test results reveal that Alcoa^® Wheels are 5 times stronger than steel: 
 – Forged Alcoa^® Wheels withstand a load of 71 200 kg before deforming
 – Steel wheels start to deform already at 13 600 kg
 
Impact test results/Japanese JWL test simulates a vehicle hitting a high curb at a speed of 50 km/h. A 910 kg weight is dropped onto the tyre and wheel assembly:
