Choosing the right coating for your aluminum parts can be a difficult task, especially considering the various plating options available in the market. However, if you’re looking for a durable and reliable coating system, then zinc nickel plating on aluminum is the way to go.
In this blog post, we will cover the benefits of zinc nickel plating and why it should be your preferred choice of coating.
Corrosion Resistance
One of the major benefits of zinc nickel plating on aluminum is its superior corrosion resistance. This plating system has been tested to withstand over 1,000 hours of salt spray exposure without any signs of corrosion. This makes it the perfect choice for parts that are exposed to harsh environments, such as marine or aerospace applications.
Wear Resistance
In addition to corrosion resistance, zinc nickel plating also offers excellent wear resistance properties. The coating system has a hardness level of 600 to 700 HV, making it resistant to abrasion and wear caused by friction. This makes it the ideal coating for parts that experience high wear, such as gears, pistons, and engine components.
Adhesion
Unlike other plating systems, zinc plating companies offer excellent adhesion to the substrate. This is due to the formation of intermetallic compounds between the zinc and aluminum, which enhances the bonding strength. This strong bond ensures that the coating does not peel or flake off even under high stress.
Environmentally Friendly
Another benefit of zinc nickel plating is its environmentally friendly nature. The process does not use hexavalent chromium, which is toxic and detrimental to the environment. Instead, it uses trivalent chromium and does not generate hazardous waste, making it a safer option for both the user and the environment.
