<pre style="background: white;"><span style="font-family: 宋体; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial;"><span style="font-size: small;">以铝为基的合金总称。主要合金元素有铜、硅、镁、锌、锰，次要合金元素有镍、铁、钛、铬、锂等。</span></span></pre> <pre style="background: white;"><span style="font-size: small;"><span lang="EN-US"><span style="mso-spacerun: yes;"><span style="font-family: Arial;">  </span></span></span><span style="font-family: 宋体; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial;">铝合金密度低，但强度比较高，接近或超过优异钢，塑性好，可加工成各种型材，具有优良的导电性、导热性和抗蚀性，工业上广泛使用，使用量仅次于钢。</span></span></pre> <pre style="background: white;"><span style="font-size: small;"><span lang="EN-US"><span style="mso-spacerun: yes;"><span style="font-family: Arial;">  </span></span></span><span style="font-family: 宋体; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial;">铝合金分两大类：铸造铝合金，在铸态下使用；变形铝合金，能承受压力加工，力学性能高于铸态。可加工成各种形态、规格的铝合金材。主要用于制造航空器材、日常生活用品、建筑用门窗等。</span><span lang="EN-US"><span style="font-family: Arial;"> </span></span></span></pre> <pre style="background: white;"><span style="font-size: small;"><span lang="EN-US"><span style="mso-spacerun: yes;"><span style="font-family: Arial;">  </span></span></span><span style="font-family: 宋体; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial;">铝合金按加工方法可以分为变形铝合金和铸造铝合金。变形铝合金又分为不可热处理强化型铝合金和可热处理强化型铝合金。不可热处理强化型不能通过热处理来提高机械性能，只能通过冷加工变形来实现强化，它主要包括高纯铝、工业高纯铝、工业纯铝以及防锈铝等。可热处理强化型铝合金可以通过淬火和时效等热处理手段来提高机械性能，它可分为硬铝、锻铝、超硬铝和特殊铝合金等。</span></span></pre> <pre style="background: white;"><span style="font-size: small;"><span lang="EN-US"><span style="mso-spacerun: yes;"><span style="font-family: Arial;">  </span></span></span><span style="font-family: 宋体;
