Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a silver-nickel-graphene alloy material and a preparation method thereof. Background technique [0002] Silver metal is a metal material with good electrical conductivity. However, silver metal has a small stock in nature and is relatively expensive. In practical applications, silver metal cannot be widely used in the field of conductive production. In addition, due to the poor hardness of the silver metal, the tensile strength of the silver wire is also poor, which further limits the application of the silver metal in the conductive field. [0003] In the prior art, different materials are combined with silver metal to enhance the performance of silver metal. Among them, nickel material has good ductility, medium hardness and good corrosion resistance, and nickel has a wide range of sources and low price. Alloy materials made of nickel and silver metal can greatly impro...
