Steel Wheels VS Aluminum Wheels
Except for extra heavy-duty vehicle wheels, aluminum wheels covered all sizes as steel wheels.
Fuel Oil Economic:
As aluminum is lighter weight than steel, such as 22.5×8.25, aluminum wheels save 2L oil than steel wheels in 100km distance, aluminum wheels also decrease 26% tire wear compared to steel wheels.
Weight:
Aluminum is half of the weight of steel wheels of the same size.
Material:
Aluminum is T6061, steel is Q grade steel plate
Manufacture Method:
Aluminum has casting, forging & extrusion shapes. To compare steel welding.
Roundness:
Aluminum wheels use CNC machining, and steel wheels rolling plate.
Dynamic:
Aluminum wheels have uniform density, steel wheels worse on roundness and welding.
Cooling:
Aluminum material has better cooling performance than steel.
Impact:
Aluminum belongs to alloy material that tensile performance better than steel.
Pressure Test:
Aluminum deforms 50mm under 73,000kgs, steel deforms 50mm under 13,600kgs.
Outward:
Aluminum has better gloss than steel.
Regarding extra heavy-duty vehicles, will still use OTR steel wheels, such as 5pcs wheels, and 7pcs wheels, which are easy to group tother and lower cost.
