The　main　problem　for　AgNi　contact　material　used　in　contactors　with　small　capacity　is　investigated,　it　is　found　that　lower　anti-welding　ability　is　the　main　factor　which　limits　the　application　of　AgNi-based　material.　Based　on　the　studies　of　welding　mechanism　of　electrical　contacts　and　the　measures　of　decreasing　tendency　to　weld　of　contacts,　a　new　AgNi-based　contact　material　for　contactor　with　small　capacity　is　developed　by　diffusing　arc　root　in　order　to　reduce　thermal　current　density　inputting　from　arc　to　electrode　surface,　enhancing　wettability　between　molten　silver　and　contact　surface　in　order　to　restrain　the　generation　and　propagation　of　micro-cracks　and　holes,　and　controlling　content　of　Ni　component　and　Ni　fibre　orientation　via　dopants　or　manufacturing　technology.　Experimental　results　on　electrical　service　life　under　AC-4　category　conducted　in　contactors　show　that　the　electrical　endurance　of　the　new　AgNi-based　material　is　improved　significantly.　This　means　that　after　taking　the　aforementioned　measures　the　anti-welding　ability　of　AgNi-based　material　is　increased　significantly.　The　remaining　characteristics　are　still　excellent　and　the　manufacturing　cost　declines　lightly.
