Connectors

1. Body materials
  • Cold rolled steel – lowest cost per unit weight of material
  • Kovar – when metal webbing is insufficient to support compression seals
  • 300 series Stainless steel – non-magnetic; corrosion resistant properties; welding compatibility to Stainless assemblies
  • Inconel – tensile strength; corrosion resistant; non-magnetic; excellent option for high pressure operating environments
  • Hymu 80 – tensile strength; corrosion resistance; non-magnetic; welding compatibility to Nickel based assemblies
  • Titanium (Ti6Al4V & CP) – light-weight; non-magnetic; tensile strength; chemical resistant in specific applications; bio-compatible; welding compatibility to Ti assemblies
  • 17-4 PH – tensile strength; not directly sealed with glass due to phase transformation temperature but suitable for attachment by welding of Inconel glass-to-metal-seals (GTMS)
  • Aluminum – thermal conductivity; light weight; machinable; welding compatibility to Aluminum assemblies
  • Hastelloy – corrosion resistance; suitable for soldering without additional plating; welding compatibility to Nickel based alloys
  • Monel – corrosion resistant; suitable for soldering without additional plating; welding compatibility to Nickel based alloys
2. Contact materials
  • Alloy 52 – for compression seals; flexibility on termination features
  • Copper cored Alloy 52 – electrical conductivity
  • Kovar – for matched seals; stiffness; flexibility on termination features
  • 446 Stainless steel – corrosion resistant; stiffness; weldable
  • 42-6 Stainless steel – stiffness; flexibility on termination features
  • Alumel – thermocouple applications
  • Chromel – thermocouple applications
  • Iron – thermocouple applications
  • Constantan – thermocouple applications
  • Paliney 7 – used for specialized applications
