Strength
Tests have proven that Alcoa® Wheels are up to 5 times stronger than their steel equivalent. To show this wheels are placed in a press until the wheel deforms by 5cm, results from this are that an Alcoa®wheel withstands a load of 71,200kg before it deforms and a steel wheel is deformed by 5cm at only 13,700kg!!
Impact Tests
The Japanese JWL tests simulate a vehicle hitting a curb at a speed of 50 km/h, the test involves a 910kg weight is dropped onto the assembly. The results are that:
- Steel wheels have excessive deformation and air loss
- Cast aluminium wheels break
- Alcoa® Wheels pass successfully!!
All of this results in less downtime for fleets and more time on the road! All Alcoa® Wheels come with 5 years unlimited mileage warranty and typically last 20 years or more in service.
