Zinc-Nickel Alloy Plating for Automotive Use: 

1. Zinc-nickel alloy plating is a commonly used surface treatment method that transforms the surface of metals (such as steel) into a harmless, corrosion-resistant, and decorative metal surface. The main components of zinc-nickel alloy plating are zinc and nickel, which provide corrosion resistance and excellent decorative effects, making it highly economically valuable.

2. In automotive surface treatment technology, zinc-nickel alloy plating is widely used and favored by automotive manufacturers due to its excellent corrosion resistance and decorative properties. In practical applications, zinc-nickel alloy plating is widely used in surface treatment processes for automotive wheels, blades, bodies, exhaust pipes, and various automotive components. Its outstanding corrosion resistance and decorative properties make it one of the most popular surface treatment technologies in the market.

3. Zinc-nickel alloy plating is one of the most important technologies in the current automotive surface treatment field, with significant application prospects. It has been widely applied in the surface treatment of automotive wheels, blades, bodies, exhaust pipes, and automotive components.

11SMnPb30 German standard implementation standard DIN EN 10087-1999 Hot-rolled bar and wire delivery technical conditions, 11SMnPb30 is a free-cutting structural steel, which is easy to be cut by (turning, milling, drawing, planing, drilling, etc.), also known as Steel for automatic machine tool processing, referred to as automatic steel. It is produced to adapt to mechanical processing automation and assembly line production. This type of steel can be cut with a higher cutting speed and a deeper cutting amount, and the cutting resistance is reduced due to the easy-cutting elements added to the steel, and the cutting edge is lubricated due to the characteristics of the added element itself and the compound formed. The role of the part makes the chips easy to break and reduces wear, thereby improving the finish and precision of the processed parts, and improving the tool life and production efficiency.
