过去常用的易切削变形铝合金有2011、6262、5056等,但是,对要求强度高、耐蚀性好、表面光洁度高、经阳极化处理后表面美观的部件来说,这些合金就不太适用了。天津市有色金属研究所在AI-Mg-Si系合金的基础上研制出一种新的易切削铝合金LKX—1。这种新合金中Mg_2Si含量在1.0％～1.6％的范围内,Si/Mg比0.45～0.7,添加了少量的Cu、Ti、Mn、Sn、Cd等。其化学成分(重量％)范围是:AI-1.0％～1.6％Mg,
In the past commonly used cutting deformation of aluminum alloy 2011,6262,5056, etc. However, the requirements of high strength, good corrosion resistance, high surface finish, anodized surface appearance of the parts, these alloys are not suitable It’s Tianjin Nonferrous Metal Research Institute developed a new free-cutting aluminum alloy LKX-1 on the basis of AI-Mg-Si alloy. The new alloy Mg_2Si content in the range of 1.0% to 1.6%, Si / Mg ratio of 0.45 to 0.7, adding a small amount of Cu, Ti, Mn, Sn, Cd and so on. Its chemical composition (% by weight) ranges from: AI-1.0% to 1.6% Mg,
