The Technology

Special process on silver wire

Our special process on silver wire creates the following features,
 (1) More conductive
 (2) More pliable
 (3) More corrosion resistant
 (4) Less heat generating
 (5) More resistant to electronic noise
Lowest Resistance Among Known Wire Materials (excluding super-conducting wire) (107.8% IACS)
Uses for Special Silver include any application where electricity is transferred.
  • Winding Wire (Magnet Wire)
  • High-frequency cable
  • High-end Audio Visual
  • Wire for Hybrid and Electric Cars
  • Solar panel
  • Wind power generation
  • Battery Recharge
  • Improved Grounding
  • Power cable
  • Medical Imaging
  • Others

Special Silver Wire Test Examples

  • When used in coaxial cable transmission efficiency is improved compared to normal coaxial cable.
    ---Test at Waseda University
  • In High Current tests, 0.8mm diameter wire can carry 30A;1.6mm diameter wire can carry 70A; and 2.5mm diameter wire can carry 100A (all with keeping temperature lower than 100℃)
    ---Tests by a Rapid Charge Device Maker
