Die-cast aluminum passivators are chemical solutions used for surface treatment of aluminum alloys. Their primary function is to enhance the corrosion resistance, wear resistance, and adhesion properties of aluminum components. The passivation process forms a protective film on the aluminum surface, reducing the metal's exposure to environmental reactions and thereby increasing its durability.
Benefits of Using Passivators:
When selecting a passivator, it is important to consider the specific composition of the aluminum alloy, intended use, and required passivation effects. Common passivators often contain chromium salts, nitrates, or other chemical components, but many manufacturers are developing chromium-free alternatives for environmental reasons.
