Why Alcoa Wheels

Why ALCOA® WHEELS?

ALCOA® WHEELS are forged from one solid block of aluminium.

Every wheel starts as a single block of high-strength aluminium alloy.
Forging process step 1
With an 8 000 tons press, the block is forged into a wheel shape. Once forged, the wheels are heat-treated to maximize overall mechanical strengths.
Forging process step 2
Precision machining ensures that each wheel is perfectly round. This eliminates any runout in a turning wheel.
Forging process step 3
 The ventilation and mounting holes are drilled.
Forging process step 4
The last step is the finishing into “Brushed”, “LvL ONE®” or “Dura-Bright® EVO”. 
Forging process step 5
 The Howmet Aerospace forging process aligns the grain flow of aluminium with the shape of the wheel. This process results in wheels with unrivalled forged strength that withstand the most severe tests.
Forging process step 6
We are so confident in the durability and quality of our wheels, we give a 5 year unlimited mileage warranty.

The best solution for your business

ALCOA® WHEELS are a must. The perfect choice for your vehicles.

Be the toughest on the road
Strength Alcoa Wheels
  1. 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
  2. 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: 
    • Steel wheels show excessive rim deformation and air loss
    • ALCOA® WHEELS pass the test successfully
Be the lightest on the scale
Weight Saving Alcoa Wheels

By switching from steel to aluminium ALCOA® WHEELS you can easily save up to
51% in weight, depending on the wheel size, allowing you to:

  • increase the vehicle’s payload
  • reduce your operating costs
  • reduce your operating costs

Alcoa Wheels are profitable
  1. Aluminium is 3 times more conductive than steel and dissipates heat better, resulting in :
    • Less tyre wear
    • Increased life duration of brakes and suspension
Be greener and cleaner
Alcoa Wheels are environmentally friendly
  1. Aluminium is 100% recyclable
  2. Contributing to fuel efficiency and improved tire performance
  3. Contributes to reduced Global Warming Potential (GWP)
    • Over the entire life cycle (720.000 km in 12 years) the forged aluminium ALCOA® WHEELS are able to reduce the GWP impact by 2,2 t to 3,6 t CO2-equivalent (eq.) for a 12 m standard city bus (6 wheels) and by 4,3 t to 4,9 t CO2-eq. for an articulated city bus (10 wheels) compared to steel wheels.*
    • Over the entire life cycle (1.300.000 km in 10 years) the forged aluminium ALCOA® WHEELS are able to reduce the GWP impact of a truck and trailer combination (12 wheels) by 4,06 t CO2-eq. compared to steel wheels.**
