Electric Steering Column Lock Body by Mg Diecasting.

This Mg diecasting item is OEM Product(HKMC OEM Automotive Component).

Development Background of this product is for lightweight with increased fuel-efficiency (Mg Alloy Material AZ91D)

The belows are Magnesium Alloy Material benefits and weakness

1. Density : Reduce Weight

 -. 23% lighter than Al(Aluminum)Alloy / 67% lighter than iron

2. Specific Strength : Stronger than iorn & aluminum at the same weight.

3. Damping Capacity

 -. Rate of Phisical Damage / Absorption is Hight / Easily reduce Noise and vibration

4. Machiability

 -. Less cutting resistance / Shot Cycle Time in CNC Process

5. Dimensional Stability : better denting resistence than iron & aluminum

6. EMI Shielding

 -. Intercept elecromagnetic wave (Bette than Plastic / Al)

7. Thermal Conductivity : Great radiation properties

8. Recyclability

 -. Excellent for Recovery of Scrap and Recycling

※ Weakness : Low corrosion resistence

 -. Easily corrodes when expose dto oxygen. Needs a coating or surface treatment
