<p align="left"><span style="font-size: 10pt;">2024-T351铝合金<br /><br /> 2024为铝-铜-镁系中的典型硬铝合金,其成份比较合理,综合性能较好。很多国家都生产这个合金,是硬铝中用量非常大的。该合金的特点是:强度高,有一定的耐热性,可用作150°C以下的工作零件。温度高于125°C,2024合金的强度比7075合金的还高。热状态、退火和新淬火状态下成形性能都比较好,热处理强化效果显著,但热处理工艺要求严格。抗蚀性较差,但用纯铝包覆可以得到有效保护;焊接时易产生裂纹,但采用特殊工艺可以焊接,也可以铆接。广泛用于飞机结构、铆钉、卡车轮毂、螺旋桨元件及其他种种结构件。<br /><br /><span style="font-weight: bold;">2024合金铝的化学成份</span></span></p> <p align="left"><span style="font-size: 10pt;"><span style="font-weight: bold;"><span style="font-size: 10.5pt; background: white; color: black; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">硅<span lang="EN-US"> 0.5%<br /></span>铁<span lang="EN-US"> 0.5%<br /></span>铜<span lang="EN-US"> 3.8-4.9<br /></span>锰<span lang="EN-US"> 0.0-0.9<br /></span>镁<span lang="EN-US"> 1.2-1.8<br /></span>铬<span lang="EN-US"> 0.10<br /></span>镍<span lang="EN-US"><br /></span>锌<span lang="EN-US"> 0.25<br /></span>钛<span lang="EN-US"> 0.15</span>(<span lang="EN-US">5</span>)<span lang="EN-US"><br /></span>其它<span lang="EN-US">(3) 0.15<br /></span>铝<span lang="EN-US">(4) </span>其余<span lang="EN-US"><br style="mso-special-character: line-break;" /></span></span></span></span></p> <p align="left"><span style="font-size: 10pt;"><span style="font-weight: bold;"><span style="font-size: 10.5pt; background: white; color: black; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;"><span lang="EN-US">物理性能:</span></span></span></span></p> <p align="left"><span style="font-size: 10pt;"><span style="font-weight: bold;"><span style="font-size: 10.5pt; background: white; color: black; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;"><span lang="EN-US"><span style="font-size: 10.5pt; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">抗拉强度<span lang="EN-US">MPa </span> <span lang="EN-US">470<br />0.2%</span>屈服强度<span lang="EN-US">MPa</span> <span lang="EN-US">325</span> <span lang="EN-US"><br /></span>伸长率% <span lang="EN-US">10<br /></span>疲劳强度 <span lang="EN-US"> 105<br /></span>硬度<span lang="EN-US">HB</span> <span lang="EN-US">120</span></span></span></span></span></span></p> <p align="left"><span style="font-size: 10pt;"><span style="font-weight: bold;"><span style="font-size: 10.5pt; background: white; color: black; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;"><span lang="EN-US"><span style="font-size: 10.5pt; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;"><span lang="EN-US"><span style="font-size: 10.5pt; font-family: 宋体; mso-bidi-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA;">电导率<span lang="EN-US">20°C </span> <span lang="EN-US"> 30<br />20°C</span>电阻率<span lang="EN-US">n .m </span> <span lang="EN-US"> 48<br /></span>弹性模量<span lang="EN-US"> </span> <span lang="EN-US">68<br /></span>密度<span lang="EN-US">KG.m-3 </span> <span lang="EN-US"> 2770</span></span></span></span><br style="mso-special-character: line-break;" /></span></span></span></span></p>
