AgNi alloy is a kind of electrical contact materials, which has excellent comprehensive performances. In this work, the preparation technology and research developments of AgNi contact material were summarized, and three main preparation methods were focused on, i.e. mechanical mixing, chemical co-precipitation and mechanical alloying. One obstacle for the use of AgNi alloy is the lack of good melting welding-resistance, so the improvement of melting welding-resistance of AgNi contact material was discussed. At last, the development directions of AgNi contact material in the future were expected.
