Nickel-coated　aluminum　powders　used　as　conductive　fillers　were　prepared　with　different　stabilizers　added　in　electroless　plating　bath.　Their　Electrical　conductivity　and　magnetoconductivity　were　measured　to　evaluate　the　effect　of　stabilizers　on　Nickel-coated　aluminum　powders.　The　results　suggested　that　the　electrical　conductivity　of　Ni-coated　aluminum　powder　was　dependent　on　the　variety　and　content　of　stabilizers　while　the　magnetoconductivity　was　irrelevant　to　the　stabilizers.　It　was　proved　that　the　concentration　and　variety　of　stabilizer　had　different　influence　on　the　microstructure　of　coating　and　changed　the　electrical　conductivity　of　Ni-coated　aluminum　powder　thereby.
