Zinc and aluminum is often referred to as a zinc-aluminum alloy.
The main components of this alloy are zinc and aluminum, and sometimes other elements such as magnesium, copper, etc., are added to improve its properties.
It have good mechanical properties, corrosion resistance and processing properties, so they are widely used in many industrial fields.
Advantages of Zinc-Aluminum Alloys
It perform well in terms of corrosion resistance and have significant advantages.
Zink-aluminiumlegering not only inherits the cathodic protection of zinc, but also combines the excellent corrosion resistance of aluminum, making it show higher corrosion resistance in pitting and cracking.
In addition, the corrosion resistance of this alloy coatings is better than that of pure zinc coatings, and thinner thicknesses can be used for the same design life.
While mechanical properties, heat resistance, and oxidation resistance are also better than those of pure zinc coatings.
Zinc-aluminum alloy properties
Mechanical properties
It has high strength and hardness, and can withstand high-strength external forces.
Its tensile strength can reach 430-550MPa, and the yield strength is between 172.8-271.4MPa, showing excellent mechanical properties.
In addition, zinc-aluminum alloy also has good wear resistance and shock absorption properties, which makes it outstanding in applications such as wear parts and shock absorbers.
Processability
Zink-aluminiumlegering is easy to cut and process, and has good ductility and plasticity, so that it can be processed into products of various shapes.
This alloy also has excellent casting properties, low melting point, good fluidity, simple forming, and does not require covering and refining.
Corrosion resistance
Zink-aluminiumlegering has good corrosion resistance, especially in atmospheric corrosive environments.
The addition of elements such as copper can further improve its resistance to atmospheric corrosion.
In addition, Zink-aluminiumlegering also has good creep resistance and corrosion resistance, making it stable in some special environments.
Thermal conductivity
Zinc-aluminum alloys also have good thermal conductivity, which makes them ideal for applications where heat dissipation is required.
Economy
It also has a low production cost and a high cost performance, so it is favored in the market.
Applications
Due to the above-mentioned excellent characteristics, zink-aluminiumlegering are widely used in automobile manufacturing, construction, electronic products and other fields.
For example, in the automotive industry, it is used in the manufacture of engine parts, body structural parts, etc.
In the field of construction, it is often used for door and window frames, railings, etc.
Haichen die-casting
Zinc-aluminum alloy has an important position in die-casting technology, especially in automobiles, communication equipment, medical equipment and other fields.
However, in order to improve product quality and extend mold life, it is still necessary to continuously optimize the alloy composition and die casting process parameters.
