For over a century, AMPCO METAL has pioneered and produced the best metal solutions for the world’s products, applications and industries.

AMS Alloys




  • Mechanical properties beyond commercial nickel-aluminium bronzes.
  • Comparable to beryllium copper at a lower cost, without the industrial hygiene requirements.

AMS-4590 is a performance nickel aluminium bronze that was initially developed as an aircraft specification alloy. As a result, its use has grown in applications where higher mechanical properties at elevated temperature, along with corrosion-resistant properties, are required.

Best used

For welding.

Ideally suited for

High ductility, high electrical and thermal conductivity, impact strength, good creep resistance and low volatility in a vacuum.
