The aluminum alloy wheels engineering process has developed a lot. Due to sophisticated wheel design, casting has become the leading manufacturing process. Alloy wheel material has evolved too: car 3sdm wheels alloys now contain silicon content, and varying contents of magnesium in addition to aluminum, in order to meet the demand for metal-mold casting properties, corrosion, and fatigue resistance.
Through the further expansion of the production process for wheel rims and naves, the engineering costs were reduced evidently so that an aluminum sheet wheel has been produced in large numbers. Using aluminum 3sdm wheels on curbside cars began with the upper class or flagship models in order to give them a characteristic personal touch. Wheels are now representing about 15% of the average aluminum content in cars and light trucks, and if the main inspiration has been styling with mainly cast solutions, mass reduction need has led to the development of more practical cast but also forged and invented solutions.
Stiffness
Structural stiffness is the basic value to deliberate when designing aluminum 3sdm wheels for sale to achieve at least the same vehicle behavior as with an equivalent steel wheel. However, material stiffness is very little dependent on alloy and temper.
Static performance
Yield strength is considered to avoid distortion under maximal axial efforts and radial ones. Misuse cases are considered in relation to ductile strength. Yield tests further down are also directed to check this behavior.
Crashworthiness
Largely, but not only, linked to stress curves in large disarticulations. Crashworthiness is beginning to be now replicated. Though, impact tests methodically check the struggle to accidental collisions.
Cooling
Whatever the type of 3sdm wheels for sale (cast, forged, strip, mixed wrought-cast, etc), aluminum dissipates heat more rapidly than steel. Further, aluminum wheels act as a very effective heat sink. This results in significant enhancements of braking efficiency, and a reduced risk of tyre overheating.
