TBC Copper – Tin bearing Copper Foil

Alloy Names (as per RoHS specifications)
DIN CEN/TS 13388 CW129C
UNS C14410
Chemical Composition Weight percentage
Copper [Cu] 99.6 % Minimum
Phosphorus [P] 0.03 % to 0.10 %
Tin [Sn] 0.07 % to 0.15 %
Iron [Fe] 0.05 % Max
Characterists
  • Possessing best thermal conductivity with extra mechanical strength due to presence of Tin [Sn].
  • Excellent hot and cold forming characteristics.
  • Resistance to annealing.
  • High tensile strength as compared to ETP copper.
  • Hardness is equivalent to ETP Copper.
Main Applications
Automobile : making fins in automobile radiator assembly for heat dissipation, Automobile battery terminals, Fuse Boxes in Automobile.
Industrial : Heat Ex-changers, Connector Pins, Radiator fins.
Corrosion Resistance
Corrosion Resistance :- AMW-16 has good corrosion resistance in natural atmosphere(also sea air) and industrial atmosphere. In different water and neutral saline solutions, it exhibits better resistance to corrosion through abrasion and pitting than SR-Cu.
