Automotive wire harness terminals, switches, and relays require high performance materials to survive the severe underhood environment where temperatures are commonly 125°C and can exceed 175°C. These materials must also meet the stringent demands of manufacturing and assembly processes. Alloy 171 was developed to meet the demanding material needs of the automotive designers.

Key benefits of Alloy 171 include:

  • Greater reliability in miniaturized design.
  • Reduced temperature rise.
  • No cost penalty when compared to other high performance alloys.
  • Easily formed into complex shapes without sacrificing strength.
  • Increased stamping productivity.
