Description
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.
