Zinc Clear — ASTM-B-633, or QQ-Z-325 (Type I, II, III)

Zinc clear ASTM B633 process, a standardized electroplating technique that provides superior corrosion resistance and a silver metallic finish for steel components.

Clear zinc plating essentially means that the zinc coating appears “colorless” or “transparent,” allowing the natural metallic color of zinc to show. Here are the key points:

Process:

 Zinc Plating: The first step involves adding zinc plating using electrical current.

Passivation: The second step treats the plated metal with a chemical passivate. For clear zinc, a clear passivate is used, leaving the metal with its natural silver color (sometimes with iridescence ranging from blue to yellow to pink).

  Advantages :

• Corrosion Resistance: Clear zinc plating provides considerable corrosion resistance.
• Strength and Abrasion Resistance: It also enhances strength and abrasion resistance.
• Affordable and Effective: Clear zinc coating is both cost-effective and efficient.

Remember, clear zinc plating doesn’t mean the zinc is truly invisible—it simply reveals the natural metallic appearance of the coating.
