Silber · 4N — Contacts, brazing and electronics

Silver Sheet and Foil

Cold-rolled pure silver sheet and foil (Ag ≥ 99.99% — 4N) from 0.025 mm thick. Used in laminated contacts for electrical switchgear, cryogenic sealing washers, brazing of dissimilar metals and power electronics. Cut to size with certificates.

  • Ag >= 99.99% · Thicknesses 0.025-3 mm · Sheared, laser-cut or punched
  • Highest thermal conductivity of all metals at room temperature (429 W/m·K)
  • Fully annealed: high ductility without strain hardening
  • Melting point 961 °C - ideal for medium-temperature brazing
  • ASTM B413 certificates with X-ray fluorescence analysis
