Trusted Surface Treatments for Mission-Critical Military Components

When it comes to defense manufacturing, failure is not an option. Components must function in the most extreme conditions—heat, cold, humidity, salt, vibration, and high-impact environments—while maintaining long-term performance. At The Lindgren Group, we specialize in defense-grade metal finishing solutions designed for the battlefield, the air, and beyond.

With full compliance to MIL-SPEC, NADCAP, and ISO 9001 standards, we help defense OEMs and suppliers protect and enhance the components that power military success. From gold plating and zinc nickel plating to hardcoat anodizing, silver plating, and connector plating, our finishes are engineered for combat-ready performance, corrosion resistance, and reliability.

Why Metal Finishing Is Critical for Military Components

Defense equipment must operate reliably in environments where maintenance is limited, stakes are high, and equipment downtime can cost lives. Without proper metal finishing, parts are vulnerable to:

  • Corrosion from saltwater or humid climates
  • Electrical failures due to oxidized contacts
  • Mechanical wear and abrasion
  • Friction and heat-related degradation
  • Field failure from improper bonding or coating adhesion

Metal finishing isn’t just about durability—it’s about defense-readiness, operational continuity, and compliance with government standards.

Our Defense-Grade Finishing Capabilities

✅ Gold Plating (MIL-G-45204, ASTM B488)

Gold is the gold standard for conductivity, corrosion resistance, and reliability in military electronics. We offer precision gold plating for:

  • Secure communications systems
  • Military-grade connectors
  • Avionics and control systems
  • Encryption and radar interfaces
  • Ground and satellite electronics

Our process ensures signal integrity even after thousands of connect/disconnect cycles, and offers optional selective plating, nickel underplating, and hard vs. soft gold finishes.

✅ Hardcoat Anodizing (MIL-A-8625F Type III)

Designed for aluminum components exposed to abrasion and corrosive environments, Type III anodizing is ideal for:

  • Weapons components and firearm systems
  • Military vehicle armor and brackets
  • Drone and UAV frames
  • Portable field equipment
  • Launch system housings

We provide Class 1 (non-dyed) and Class 2 (dyed) anodizing with optional sealing, masking, and tight-tolerance control for tactical durability and stealth.

✅ Zinc Nickel Plating (AMS 2417, MIL-DTL-26074)

As a cadmium alternative, zinc nickel plating is increasingly adopted by defense suppliers for its:

  • High corrosion resistance (1,000+ hours salt spray)
  • Low environmental impact (RoHS compliant)
  • Strong adhesion to complex geometries
  • Long service life under marine or desert conditions

It is ideal for fasteners, brackets, structural hardware, and underbody vehicle components in tanks, planes, and transport vehicles.

✅ Silver Plating

Silver’s high conductivity and thermal transfer make it essential for:

  • Power connectors in radar and surveillance systems
  • EMI/RFI shielding in secure comms
  • High-temperature contacts in engine or generator components

We meet ASTM B700 and other defense standards for silver purity and thickness.

✅ Tin Plating

Tin provides a solderable, economical, and RoHS-compliant finish for military electronics and wire termination applications, including:

  • Power converters
  • PCBs and terminal blocks
  • Secure data storage devices
  • Night vision systems

We offer bright or matte tin finishes, with optional lead-free plating for sensitive defense applications.

✅ Connector Plating

Defense systems rely heavily on connectors to keep operations running smoothly. We offer:

  • Selective plating for multi-surface finishes (e.g., gold on contact, tin on shell)
  • Low-resistance gold plating for signal integrity
  • Silver and tin plating for grounding and power applications
  • Precision masking for high-density MIL-DTL-38999 and other military connectors

Commonly Plated Military Components

Our finishing processes are applied to a wide range of parts and equipment used by the U.S. Department of Defense and its suppliers, including:

  • Connectors and backshells
  • Circuit boards and enclosures
  • Fasteners and brackets
  • Weapon system housings and rails
  • Aerospace and rotorcraft parts
  • Satellite and comms interfaces
  • Night vision gear and optics
  • Ruggedized laptops and electronic systems

Whether it’s a radar module, a missile guidance component, or a mobile generator unit, we help ensure every component is ready for service.
