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.
What are Zinc and Aluminum?
Zinc and aluminum are different metals with unique characteristics.
Zinc is a soft, silvery-white metal that finds application in various fields, including galvanizing steel for corrosion protection, die-casting, and brass production.
Aluminum is a lightweight and sturdy metal used in diverse applications such as aircraft construction, beverage cans, and window frames.
Zinc and aluminum can be combined to form various alloys with distinct properties.
What is Zinc Alloy?
Zinc alloy refers to a metal alloy composed primarily of zinc, along with other metallic elements.
The common elements used in zinc alloy include aluminum, magnesium, copper, cadmium, lead, titanium, and other low-temperature zinc alloys.
Zinc alloys are prepared by melting the constituents and processing them through die-casting or other pressure-shaping methods to obtain the desired material form.
Features of zinc alloy
It has excellent casting performance, enabling the production of intricate and thin-walled precision parts with a smooth surface finish.
Enables surface treatment options such as electroplating, spraying, painting, polishing, and grinding.
During the melting and die-casting processes, it doesn’t absorb iron, resists pressure corrosion, and does not adhere to molds.
Possesses favorable mechanical properties and offers wear resistance at ambient temperatures.
Boasts a low melting point of 385℃, facilitating easy die casting.
Advantages of zinc and aluminum alloy
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.
