Zinc-aluminum-magnesium steel

Zinc-aluminum-magnesium related steel mainly refers to steel coated with zinc-aluminum-magnesium alloy. The technology of this coating is to add elements such as aluminum and magnesium during the hot-dip galvanizing process to form a special metal alloy layer.

Manufacturing process

1. Alloy coating: In the process of hot-dip galvanizing, a zinc-aluminum-magnesium alloy coating is formed by adding alloy elements such as aluminum and magnesium.

2. Hot-dip galvanizing: The steel is first pre-treated by pickling and then immersed in molten zinc-aluminum-magnesium alloy liquid to form an alloy coating on its surface.

Advantages of zinc-aluminum-magnesium materials

1. High strength: equivalent to the strength of steel, suitable for lightweight applications.

2. Corrosion resistance: excellent anti-corrosion performance in a variety of environments.

3. Good processability: suitable for a variety of processing processes such as casting, forging, rolling and stretching.

Uses of zinc-aluminum-magnesium materials

1. Used in the production of zinc-aluminum-magnesium coils, strips and pipes.

2. It is divided into high zinc layer and ordinary zinc material. The high zinc layer can reach 275g, with no spots on the surface, and is more corrosion-resistant than galvanized strip steel.
