Advantage |
Description |
|
Excellent formability |
Suitable for various cold - forming processes such as stamping, bending, and drawing, facilitating the production of complex - shaped components. |
|
Good corrosion resistance |
The zinc coating on the surface isolates the base metal from the external environment, effectively preventing rust and corrosion, and prolonging the service life. |
|
Favorable surface quality |
Has a smooth and clean surface, which is beneficial for subsequent painting, coating, and printing processes, and ensures good adhesion of the coating. |
|
Good weldability |
Easy to weld with other components, enabling the production of reliable and strong structures. |
|
Cost - effectiveness |
Offers a good balance between performance and cost, with relatively low cost and excellent properties, reducing overall costs. |
|
Wide range of applications |
Widely used in the automotive, construction, and home appliance industries, etc. |
