Non-Ferrous & Copper Based Alloys

Most springs have a common goal, which is to store and release mechanical energy as required. For applications needing corrosion and heat resistance or thermal and electrical conductivity, springs made of ferrous materials may not be the best choice. Excel in these challenging environments with non-ferrous alloy springs from Custom Spring Manufacturing.

Non-Ferrous Alloy Springs Explained

Non-ferrous alloys lack the iron content of ferrous materials. There are many different types of non-ferrous alloys, and many of them are used to make springs and wireform products for demanding applications. While all different, they share a variety of characteristics:

  • High Corrosion Resistance
  • Easily Machinable
  • High Ductility
  • Good Weldability
  • High Temperance Resistance
  • Great Thermal Conductivity
  • Strong Electrical Conductivity
  • Lower Mass
  • Non-Magnetic

Common Non-Ferrous Alloys For Springs

At Custom Spring Manufacturing, we design and make high-performing finished products from non-ferrous alloys for use in many industries. While we can work with just about any non-ferrous material you need, those we use most often are copper-, nickel-, and aluminum-based.

Phosphor Bronze
Phosphor bronze, commonly known as Phos Bronze, is an alloy comprised primarily of copper, tin, and phosphorus. It’s exceptionally strong and resilient, making it ideal for products where resistance to fatigue, wear, chemical corrosion, and elemental exposure is required. This alloy also offers good electrical conductivity, a low coefficient of friction, and excellent elasticity. Phos Bronze’s unique performance attributes mean it’s often used to manufacture springs for electronic, automotive, and aerospace applications.

Beryllium Copper
Beryllium copper is copper alloyed with up to three percent beryllium and other elements. The elevated amount of beryllium results in the greatest strength of all copper-based alloys. Commonly called spring copper or beryllium bronze, its strength is comparable to alloy steel, but without the weight. The material is also non-magnetic, non-sparking, corrosion-resistant, and withstands toxic environments, which makes beryllium copper springs perfect for electrical applications.

Aluminum
Aluminum is a soft and silvery-white metal that’s strong, lightweight, and stands up to harsh atmospheres. It naturally generates a protective thin oxide coating, which protects against corrosion and degradation. This material also has a long life and is completely recyclable, making it environmentally friendly.

Nickel
Nickel is prized for its ability to maintain strength at incredibly hot and cold temperatures. It also has good solderability and thermal conductivity. The material is tough and ductile, which is why nickel springs are used in extreme environments. Nickel alloys are preferred when the strength of stainless steel doesn’t meet the demands of the application.


Applications For Non-Ferrous Alloys

With a wide variety of non-ferrous metals available, Custom Spring Manufacturing can produce springs with the performance attributes needed to excel in just any operating environment. Common industries that can benefit from integrating non-ferrous alloy springs into their applications include:

  • Oil & Gas
  • Mining
  • Nuclear
  • Marine
  • Solar & Wind
  • Transportation
  • Aerospace
  • Automotive
  • Valve
  • Military
  • Agriculture

Nickel’s toughness, tolerance to high and low temperatures, and corrosion resistance make it well suited for the harsh conditions of oil and gas production or chemical processing applications.

Copper-based alloys are widely used to manufacture springs and wireforms for electronic applications. This is because copper has superior electrical conductivity and relatively low weight. Copper alloys are also used to make springs for musical equipment, industrial machinery, roofing, valves, and tools.

Lightweight, able to reflect radiant energy, and resist corrosion, aluminum is an excellent material choice for springs used in aerospace, marine, and railway applications. It’s also used to manufacture springs for bicycles, motors, and generators.
