Difference between steel and alloy wheels

Points

Forged Aluminum Wheel

Steel Wheel

Aluminum wheel Advantages

1. Weight

~24KGS

~45KGS

Half lighter than steel one

2. Material

High strength forging alloy

Steel Plate

Higher strength

3. Manufacturing method

Rotary forging

Stamping, Rolling,Welding

Forged from whole blank wheel, no weld-joint

4. Circularity

Numerical Control

Rolling

Roundness

5. Dynamic balance

Uniform Density

Smooth-ride in high speed

6. Heat radiation

High density no bubble,high conductivity for heat

Less conductivity for heat

Expand service life of tyres by 26%

7. Impact resistance test

 Almost zero Demage

Damage seriously

Higher safety

8. Rigidity

Rigid

Deformable

Protect tyres from eccentric wear

9. Compression resistance

73000KGS deformed 5CM

13600KGS deformed 5CM

High intensity, 5.37times than steel ones

10. Appearance

Polished, Fine and Smooth

Murky grey, rough

Polished, Fine and Smooth

11. Cost

3-4times Than Steel one

Low cost

3-4times Than Steel one

12. Recycle

95% recycled

95% recycled

13. Environment protect
