Hard Alloy Aluminium in action
High strength, high resilience, extreme flexibility and low weight, those are the best arguments for using high-strength aluminium alloys. Take automobile construction as an example. The proportion of aluminium in current vehicles has increased by around 300% in the last twenty years. Two thirds of Formula 1 racing cars are made of aluminium – despite strong competition from carbon or titanium. 7000 series alloys are penetrating domains where steel was previously used and is replacing parts such as light-weight B pillars in cars.

Let’s stay with automobile construction: ABS housings are manufactured from aluminium. For example, wire race bearings are used for seamless wheel rims in Formula Student race cars. Aluminium scores points here with its high resilience and minimum space requirements.
Aluminium alloys are the material of choice for aircraft seats or stiffeners in aircraft wings.
Further typical application areas for components manufactured from high-strength aluminium:
- Seamless pipes
- Wire race bearings
- Rolled discs
- Floor beams
- Pistons and piston rods
- Control arms and track rods
- Structural pipes, control rods and hydraulic pipes for transporting liquid
- Rotating parts, precision engineering
- Chassis and hull structures
- Gas and pressure cylinders
- Cable housing
- Door locking systems
- Pipes for cooling systems and drills for oil and gas extraction
The list is not complete by far but offers a good overview of the numerous uses of aluminium.
