In the world of aerospace, defense, electronics, and industrial manufacturing, parts don’t just need to work—they need to last. Every extra hour of performance, every cycle without failure, and every season without corrosion adds value. That’s why companies across critical industries trust The Lindgren Group for precision metal finishing services that are built to go the distance.

From gold plating and hardcoat anodizing to zinc nickel plating, silver plating, tin plating, and connector plating, our finishing processes are engineered to extend component life, reduce maintenance costs, and deliver better long-term performance.

Why Longevity Matters in High-Stakes Industries

Short product life cycles aren’t just inconvenient—they’re expensive. Failures in the field, corrosion in flight-critical parts, or faulty connectors in defense systems can result in:

  • Costly downtime
  • Risk to safety
  • Damaged reputations
  • Delayed timelines and compliance issues

With the right metal finish, however, your parts can operate longer, with less wear, less corrosion, and greater consistency.

Metal Finishing Techniques That Add Years to Performance

Gold Plating

Ideal for connector plating, circuit boards, and signal-critical electronics, gold is non-reactive and extremely resistant to corrosion. That means:

  • Zero oxidation
  • Longer electrical contact life
  • Fewer maintenance cycles

Gold-plated parts are a go-to in aerospace and military communication systems, where consistent performance over time is critical.

Hardcoat Anodizing

This is the long-life armor for aluminum. Used across aircraft, industrial machinery, and tactical equipment, hardcoat anodizing:

  • Increases surface hardness
  • Reduces wear from abrasion and friction
  • Resists corrosion without added weight

A properly anodized part can last 3–5 times longer than untreated aluminum.

Zinc Nickel Plating

When it comes to corrosion protection, zinc nickel is the long-haul champion. It provides:

  • Up to 1,000+ hours of salt spray resistance
  • Superior adhesion and wear resistance
  • Performance in wet, salt-heavy, or chemical environments

Used in automotive, defense, and aerospace hardware, zinc nickel helps critical components endure the harshest conditions.

Silver Plating

Silver is not just conductive—it’s thermally stable and highly reflective. For parts under thermal and electrical stress, silver plating provides:

  • Long-term conductivity
  • Resistance to oxidation at elevated temperatures
  • Extended performance in high-power systems

It’s the finish of choice for RF connectors, switches, and power transmission components.

Tin Plating

While it’s more budget-conscious, tin plating still delivers excellent lifecycle value when used properly. It offers:

  • Corrosion resistance for indoor applications
  • Strong solderability
  • Long-term protection for electronic contacts

It’s widely used in telecommunications, consumer electronics, and electrical assembly.

Connector Plating

No matter the metal—gold, silver, or tin—reliable connector plating ensures signal integrity over time. We apply finishes engineered for:

  • Extended mating cycles
  • Vibration resistance
  • Stable conductivity in harsh conditions

From satellites to submarines, we finish connectors that stay connected.
