What is Zinc Electroplating?
Zinc electroplating is a widely used metal finishing process that applies a soft, ductile, and corrosion-resistant coating to a metal surface. Unlike other finishes, zinc protects the base metal by acting sacrificially, meaning the zinc layer corrodes before the underlying material does. This sacrificial protection helps extend the life of components in moisture-prone or corrosive environments. Zinc plating also offers a clean, decorative appearance and serves as an ideal base for post-finishing treatments.
How It Works
The zinc plating process at Advanced Metal Finishing is engineered to meet strict quality and industry specifications. After plating, the zinc layer can be enhanced with a chromate coating, which adds further corrosion resistance without contributing significant thickness. Chromate finishes are chemically bonded to the zinc and serve as a passive barrier, improving performance in harsh conditions. Although thin, these chromate films are essential to maximizing protection.
Finishing Options
We offer several zinc finish types, including Clear Zinc, Black Zinc, Yellow Zinc, and Trivalent Yellow. AMF features a top of the line oven for option hydrogen embrittlement relief. Each variation provides different levels of corrosion resistance and appearance, depending on the specific use case. The finish color can help determine performance expectations in environmental exposure tests.
Benefits of Zinc Plating
- Provides sacrificial protection for the base metal
- Enhances corrosion resistance, especially with chromate sealing
- Maintains ductility and does not embrittle parts
- Offers decorative appeal in both clear and yellow finishes
- Supports a wide range of industrial and consumer applications
Zinc electroplating is a cost-effective, reliable solution for extending part longevity while ensuring functional and aesthetic quality. Whether you’re working with hardware, fasteners, or components for automotive and electrical applications, zinc remains a trusted finish.
