<h3 class=“headline-2 bk-sidecatalog-title“><span style=“FONT-SIZE: medium“><span class=“headline-content“>特性</span></span></h3>
<p><span style=“FONT-SIZE: medium“> 3A21铝板为Al-Mn系合金,3A21铝板是应用较广的一种防锈铝,强度不高(仅稍高于工业纯铝),不能热处理强化,故常采用冷加工方法来提高其力学性能;在退火状态下有高的塑性,在半冷作硬化时塑性尚好,冷作硬化时塑性低,耐蚀性好,焊接性良好,可切削性能不良。</span></p>
