Forged magnesium wheels are extremely durable and rigid. The strength of a forged wheel made from magnesium alloy exceeds many times the strength of a cast Al disk. This is achieved by forming a unique fiber structure of the alloy manufactured by the precision 3-D hot forging process in a press with a 20,000 ton capacity.
A forged wheel does not crack; it bends without cracking and can be easily repaired, if necessary. Common casting defects, such as cavities and cracks, are non-existent in forging. So our forged magnesium wheels are stronger and more durable. Also, all forged magnesium wheels produced by SMW Engineering undergo strict quality control to comply with road safety requirements.
Forged magnesium wheels are very lightweight, as much as 1.5 times lighter than aluminum wheels, and 2.2 times lighter than steel wheels. Our forged magnesium wheels are twice as light compared to cast Al wheels of the same dimensions.
SMWE has partnership with Solomon Alsberg, you can visit our catalogue with magnesium wheels.
Cast and forged magnesium wheels and aluminium alloy wheels weight comparison:
|Forged wheels||7.3 kg||11 kg|
|Cast wheels||10 kg||15 kg|
Wheel weight is a key component in “un-sprung” mass of an automobile (tires, wheels, brake disks, etc.), which directly affects vehicle performance parameters and the lifetime of suspension components. A lighter wheel is much easier to spin and to stop due to a lower momentum of inertia. Forged magnesium wheels yield shorter braking distance and faster acceleration, improve maneuverability and overall performance and safety, and reduce fuel consumption (by up to 5-7%).
The dampening ability (the absorption of shocks and vibrations caused by road imperfections) of magnesium alloys is 100 times higher than those made from aluminum and 23 times higher than steel. This promotes increased durability of suspension brackets, smooth and easy motion of the car, and a longer lifetime of the suspension and brakes.
The high heat conductivity property of magnesium also means cooler brake disks and brake drums and a longer life for brake pads.
Due to the specific metal structure obtained in the forging process, forged magnesium wheels are decidedly more corrosion-resistant than cast magnesium wheels.
