Bronze Alloys and Their Applications

Accurate Specialties, Inc. offers a wide selection of bronze alloys to serve the varying needs of our clients. Various alloys can be created specifically to meet the needs of even the most unique or demanding applications. By consulting with each client, we will determine the best choice for your intended purpose or design. Some of the most common alloys we use include:

 

863 Manganese Bronze

Known for its high-strength and corrosion-resistance, this bronze alloy also features durability and longevity, making it an ideal option for heavy-duty applications such as construction and agricultural equipment. 863 Manganese Bronze is popular in bronze alloy applications such as:

  • Screw-down nuts
  • Load bearings
  • Bronze for gears
  • Cams
  • Gibs
  • Large stem valves
  • Bridge pins
  • Hydraulic cylinder components

 

907 Tin Bronze

This alloy offers quality corrosion resistance, especially in applications with seawater exposure. This bronze alloy is moderately machinable and performs well in wear and fatigue applications. 907 Tin Bronze is utilized in bronze alloy applications such as:

  • Bearings
  • Bushings
  • Bronze for gears
  • Piston rings
  • Pump components
  • Marine fittings

 

917 Tin Bronze

Typically selected for its increased load carrying capacity – especially heavy loads involving slow and irregular movement – this alloy is highly corrosion resistant and requires adequate lubrication.

917 Tin Bronze is commonly used for applications such as:

  • Bearings with slow speed and high load
  • Gears
  • Movable bridge components
  • Wheels in worm drives
  • Turntables for bridges

 

954 Aluminum Bronze

This extremely strong bronze alloy  features superior corrosion resistance. It is the most popular aluminum bronze alloy, selected for its exceptional elevated temperature strength, weldability, high tensile and yield strength, as well as ductility. 954 Aluminum Bronze is commonly used in bronze alloy applications such as:

  • Worms and worm gears (low speed/high strength)
  • Spur gears
  • Bushings
  • Bearings
  • Pickling (baskets/hooks)
  • Valve components

 

955 Aluminum Bronze

This alloy is among the toughest non-ferrous alloys available. It offers superior yield and compressive strength with high hardness and elongation. 955 Aluminum Bronze offers good corrosion resistance to seawater, as well as impressive heat resistance. It is weldable with good machinability. 955 Aluminum Bronze is found in applications including:

  • Bushings
  • Agitators
  • Landing gear components
  • Bronze for gears
  • Pickling (baskets/hooks)
  • Worms
  • Aircraft engine (seats, valve guides)
