AMS 2424 Silver Plating

Specification Overview

AMS 2424 outlines the aerospace requirements for electrodeposited silver coatings on metallic substrates. The standard specifies purity, thickness, adhesion, porosity testing, and thermal characteristics for high-reliability applications. Silver is chosen for its unmatched electrical and thermal conductivity.

• Purity: 99.9% minimum silver content
• Thickness: Typically 5μm to 25μm (custom available)
• Testing: Adhesion, porosity, solderability, and conductivity tests
• Anti-Tarnish: Optional chromate or immersion coatings

Applications & Capabilities

• RF connectors and coaxial interfaces
• Electrical busbars and contact surfaces
• Satellite and avionics components
• High-current switchgear and terminal blocks
