铁基烧结制品虽然具有较高的强度,但一般需在1097—1183℃高温烧结。为了降低烧结温度,日本早稻田大学铸造研究所作了各种试验,发现在还原铁粉中添加2.5—5％wt锡—铜配比为3:7的锡—铜合金粉或混合粉,可使铁基制品的烧结温度降至887℃左 Iron-based sintered products, although with high strength, but generally need to 1097-1183 ℃ high temperature sintering. In order to reduce the sintering temperature, the Institute of Foundry, Waseda University, Japan made various experiments and found that adding 2.5-5% tin-copper alloy powder or mixed powder with tin-copper ratio of 3: 7 in reduced iron powder can make iron Base product sintering temperature dropped to 887 ℃ left
