Detailed Description

Product Overview

With growing environmental regulations and increasing demand for nickel-free and lead-free coatings, FH-760 has been widely adopted in industries such as electronics, hardware, automotive, jewelry, and decorative finishing. This plating process ensures bright, uniform, and corrosion-resistant deposits, making it a superior choice for manufacturers who value both performance and compliance with global environmental standards.

Detailed Product Introduction

Electroplating technology is evolving towards environmental protection and high-performance surface finishing. The FH-760 plating process was developed to address the limitations of traditional nickel-based plating systems, which often cause allergic reactions and environmental pollution. By eliminating both lead and nickel, FH-760 offers a health-friendly and environmentally responsible alternative while maintaining the excellent appearance and protective performance of white copper-tin coatings.

This plating process produces a smooth, bright, and silver-white deposit that is highly resistant to corrosion, tarnishing, and wear. It provides excellent adhesion to a wide variety of substrates, including copper, brass, zinc alloys, and other base metals commonly used in electronics and decorative plating.

Engineered under strict ISO9001:2004 quality management standards, FH-760 integrates advanced international electroplating additive technologies and has been proven to deliver reliable performance across manual, rack, and automatic plating lines.
