Courant-faible Contact Alloy is a Conduct Component to form or clear Electric Contact, classified in Courant Fort, Intermediate Current and Courant Faible. But there is no strict boundary among the three Charges.

Courant-faible Contact Alloy is used to manufacture some Critical Material in Slather Electric-contact Components in the line of Instruments, Telecommunication and Electronic Devices.

Based on Tunnel Effect, Courant-faible Contact Alloy requires Small & Stable Resistance. And in order to avoid Electric Erosion, Courant-faible Contact Alloy also requires Better Electrical Conductivity, Better Thermal Conductance, High Fusing Point, High Boiling Point, Low Vapour Pressure  as well as Anti-friction plus Certain Mechanical Strength.

In all Conductors, such Precious Metals as Aurum, Argentine, Platinum posses Best Chemical Stability but too Expensive to be industrialization. Therefore, in practice, such Compound Methods are utilized as Electric Galvanization, Cladding, Welding, Riveting, Vacuum Surface Sediment to reduce the Consumption of Precious Metals.

The Practical Classes of Compound Contact Alloys are Ag-Cu Alloy, Ag-Ni Alloy, Ag-Mg-Ni Alloy, Ag-Cd Alloy, Ag-Pd Alloy and so forth.
