CFA Applications

  ● Pantograph for High Speed Trains
   - Conventional material is sintered alloy of Copper and Iron, which is worn easily with the abrasive
     dust adhering on the train roof in large quantities, and with low electric conductivity the economic
     efficiency is also low.
     If made with CFA material, it will be less abrasive and have less dust. With high electric conductivity,
     the economic efficiency is also very high.

  ● Brake Pads for Automobiles
   - CFA has characteristics of not wearing down the opposite metals, and “A” Brake Co.
   - Japan made brake pads of CFA with Chrome material, which have passed the tests.

  ● Switches and Relays for Streetcars
   - Switch of streetcars is very big and silver is used for its contacts.
     And very big L-shaped Relay takes high current, producing sparks which causes problems of damaging
     switch contacts and relays.
     But with CFA 30 which contains Iron, sparks make not much damage and Iron content is not much
