3 Things to Look for in an Aerospace-Grade Silver Plating Partner

Silver plating plays a critical role in aerospace applications. From ensuring low-resistance electrical connections to offering reliable thermal conductivity and corrosion resistance, it is one of the most trusted surface treatments used in high-reliability environments. But in aerospace, it’s not just about the metal – it’s about the process behind it.

When you’re sourcing a silver plating partner for aerospace components, you’re not just buying a service. You’re trusting them with your performance, your compliance, and in some cases – your mission.
Here are three essential factors to evaluate before you choose your aerospace silver plating partner:

1. Proven Process Control for Aerospace-Grade Consistency

In aerospace systems, consistency isn’t a value-add, it’s a baseline. Components such as electrical connectors, control modules, and power systems require tightly controlled plating thickness, uniform coverage, and zero compromise on adhesion.
A reliable partner should demonstrate:

  • Process validation across batches
  • Tight control over deposit thickness (especially for selective silver plating)
  • Internal capability for cross-section analysis and quality checks
  • Documentation and traceability of every lot

At Sargam, we have long worked on selective silver plating for industries that demand process discipline from defence to power transmission & distribution. We’ve extended the same controls to aerospace parts.

2. Capability to Handle Complex Selective Plating Requirements

Aerospace components rarely need full-surface plating. Most require selective silver plating – for example, plating only on:

  • The contact points of a connector
  • The inner diameter of a machined cavity
  • A very specific pattern on a heat-sensitive substrate

This requires precision masking, tooling design, and often plating on less than 1% of the total surface area.

A qualified partner should be able to:

  • Design custom fixtures and jigs for complex geometries
  • Handle minimal surface plating without bleed or over-deposit
  • Maintain dimensional tolerances post-plating
  • Work across a range of aerospace base materials (e.g., stainless steel, aluminum alloys, copper)

At Sargam, we build all fixtures in-house, enabling fast turnaround and tighter control for aerospace components that demand high precision.

3. Experience with Critical Applications and Quality Expectations

Aerospace plating is not for general-purpose shops. Your partner should have a track record with high-performance industries where plating failure is not acceptable.

Silver plating in aerospace is commonly used in:

  • Electrical connectors for cockpit systems and avionics
  • RF and microwave components in communication and radar modules
  • Thermal interface components in satellites and control units
  • EMI/RFI shielding in electronic enclosures
  • Satellite systems, where oxidation resistance in vacuum is critical

Sargam has been serving high-stakes industries with these exact demands. Aerospace is not new for us, it’s a continuation of our focus on selective, functional, and critical plating.
