The benefits of using Mg alloy material  in today's automobiles industry are obvious，especially in new energy vehicles.

Mg alloys as one of the lightest structural metals ，It's 75% lighter than steel, 33% lighter than aluminum. it has become one of the main directions to use low-density magnesium alloy materials for the future development of automotive materials

1.The lightness of material can indirectly reduce fuel consumption
2.Mg alloys easy to machined and cast.
3.It has good magnetic shielding, excellent thermal conductivity and recyclability

In order to  apply Mg alloys in many different fields, it is often necessary to change the surface state to enhance the corrosion resistance, wear resistance, decorative properties and so on. electroless Ni plating is one of the most ideal surface treatment methods for Mg alloys , which can obtain uniform thickness coating on complex castings, thus improving the corrosion resistance and wear resistance of magnesium alloy products.
