Aluminum zinc is a metal alloy with superior properties. It is a good choice for manufacturing intricate parts and components. Compared to aluminum, it has better thermal conductivity, high tensile strength, and impact resistance.
Zinc is a common metal used in batteries. In fact, it is one of the most commonly used metals in the world. It is also a fair conductor of electricity.
Zinc is a very hard metal that has a very low melting point. Therefore, it is easy to weld and cast. Moreover, the alloy is also resistant to corrosion. This makes it ideal for casting thin walls.
Aluminum is a stronger metal and has a higher temperature for melting. However, the molten metal flows fairly quickly. Hence, it is difficult to produce a smooth surface. Also, it is more expensive than zinc.
The aluminum-zinc alloy in hot dip process delivers excellent oxidation-resistance and formability. Additionally, it offers heat reflectivity, galvanic protection, and corrosion resistance.
Zinc-aluminum alloys have a lamellar structure. Alternating Zn and Al nanolamellas provide a positive electrostatic shield to prevent reduction of Zn2+. Moreover, the less noble Al lamellas form interlamellar patterns.
Another important characteristic of this alloy is its reversible plating. Anodes made from zinc anodes tend to have heavy dendrite growth during plating. They also have a lower coulombic efficiency.
Aluminum anodes are well suited for brackish water and seawater. Because of the high relative energy capacity of the anode, they can be applied to aqueous rechargeable batteries.
