The present application provides a lightweight electromagnetic shielding multi-element metal fabric and a preparation method thereof. The fabric prepared by the present application has a wide frequency band of electromagnetic protection and strong protection effect, and the combination of nickel silver and the base cloth is firm, and has good wear resistance and oxidation resistance, effectively combining the advantages of silver and nickel. The advantages of silver are strong conductivity and good shielding effect, but the disadvantages are poor friction resistance, easy oxidation, fast shielding performance decay with washing or time, high cost, and nickel has the advantages of friction resistance, not easy to oxidize and not easy to decay. The nickel is wrapped outside the silver, which can effectively protect the silver from friction, oxidation and shielding decay. The cost of nickel is relatively low. The multi-element metal fabric prepared has a weight of 65-68g / m 2 , and a comfortable hand feeling, which is not different from ordinary cloth.
