aluminium plate L2-Y2?L2Y2 is an industrial pure
aluminum sheet:1, L2: China\'s industrial pure aluminum grades are limited by impurities to prepare, such as L1, L2, L3...... L, is the \"aluminum\" word Pinyin prefix, followed by the attached order number is bigger, its purity is low. Industrial pure aluminum is generally defined as aluminum with a purity of 99% to 99.9%, and China is designated as 98.8% - 99.7% aluminum.China plastic deformation of pure aluminum grades are 1080, 1080A, 1070, 107000A (L1), 1370, 1060, 1050 (L2), 1050A (L3), 1A50 (LB2), 1350, 1145, 1035 (L4), 1A30 (L4-1), 1100 (L5-1), 1200 (L-5), 1235. Iron and silicon are their major impurities and are increasing by the number of brands.2, Y2: indicates that the material is in a semi hard stateL2 is the old number, the new brand corresponds to 1060, and the same Y2 is also the old number to indicate the state of the heat treatment method, the new method of expression is H24, which means semi hard state.
