AMPCO® 45 is a high strength alloy with mechanical properties beyond the range of commercial nickel-aluminium bronzes. This is due

to its special manufacturing process.

 

APPLICATIONS: 

AMPCO® 45 is recommended for heavy-duty high-loaded mechanical and corrosive applications. Typical applications involving abrasive wear, friction, deformation, chemical erosion include:

  • aircraft bearings / bushings
  • pump and marine shafts and wear rings
  • valve spindles and seats
  • machine tool parts

The spark-resistance properties make it suitable for safety tools and machine tool components in explosive environments.
