4.3烧结铁镍合金和烧结镍钢烧结铁镍合金与烧结镍钢是由纯铁粉、纯镍粉与石墨粉的混合粉制造的。镍的添加量一般为1％～4％。不含碳者称之为烧结铁镍合金。石墨粉和（或）镍粉的添加量取决于所要求的强度水平和材料是于烧结态还是热处理态使用。还可添加其他合金元素（如钥），
4.3 Sintered Iron-Nickel Alloy and Sintered Nickel Steel Sintered iron-nickel alloy and sintered nickel-steel are manufactured from a mixture of pure iron powder, pure nickel powder and graphite powder. The amount of nickel is generally 1% to 4%. Carbon-free people call it sintered iron nickel alloy. The amount of graphite powder and / or nickel powder added depends on the level of strength required and whether the material is used in a sintered or heat treated state. You can also add other alloying elements (such as key)
