Graphite and metallic silver 1+1＞2

Method:

 1) silver impregnated, silver content 30%-40%

2) Graphite and silver mix pressed, 50% graphite +50% silver

The advantages of combining graphite and silver primarily lie in the synergistic improvement of material properties. Specific advantages are as follows:

Synergistic Performance Improvement

Silver-graphite alloys are formed by sintering a mixture of silver and graphite powders to form a three-dimensional network structure. This alloy combines the high conductivity of silver (resistivity as low as 0.08 μΩ·m) with the wear resistance and self-lubricating properties of graphite, resulting in stable contact resistance and excellent resistance to welding.

Applications:

Silver-graphite alloys are widely used in medium-current contact components such as sliding parts in electrical equipment and circuit breaker contact assemblies. New designs (such as a nitrile rubber waterproofing layer and aluminum heat sinks) further enhance their waterproofness and heat dissipation efficiency.
