<p align="left"><strong>2024</strong><strong>-</strong><strong>T351</strong><strong>合金</strong></p> <p align="left"><strong>2024</strong><strong>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</strong><strong>150°C</strong><strong>以下的工作零件。温度高于</strong><strong>125°C</strong><strong>,</strong><strong>2024</strong><strong>合金的强度比</strong><strong>7075</strong><strong>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</strong><strong>;</strong><strong>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。</strong><strong><br /></strong><strong>2024</strong><strong>合金铝的化学成份</strong></p> <table border="1" cellspacing="1" cellpadding="0"> <tbody> <tr> <td rowspan="2" width="39"> <p align="center"><strong>硅</strong><strong>Si</strong></p> </td> <td rowspan="2" width="33"> <p align="center"><strong>铁</strong><strong>Fe</strong></p> </td> <td rowspan="2" width="92"> <p align="center"><strong>铜</strong><strong>Cu</strong></p> </td> <td rowspan="2" width="98"> <p align="center"><strong>锰</strong><strong>Mn</strong></p> </td> <td rowspan="2" width="118"> <p align="center"><strong>镁</strong><strong>Mg</strong></p> </td> <td rowspan="2" width="59"> <p align="center"><strong>铬</strong><strong>Cr</strong></p> </td> <td rowspan="2" width="65"> <p align="center"><strong>锌</strong><strong>Zn</strong></p> </td> <td rowspan="2" width="39"> <p align="center"><strong>钛</strong><strong>Ti</strong></p> </td> <td colspan="2" width="79"> <p align="center"><strong>其它元素</strong></p> </td> <td rowspan="2" width="33"> <p align="center"><strong>铝</strong></p> </td> </tr> <tr> <td width="39"> <p align="center"><strong>每个</strong></p> </td> <td width="39"> <p align="center"><strong>总计</strong></p> </td> </tr> <tr> <td width="39"> <p align="center"><strong>0.5</strong></p> </td> <td width="33"> <p align="center"><strong>0.5</strong></p> </td> <td width="92"> <p align="center"><strong>3.80</strong><strong>-</strong><strong>4.90</strong></p> </td> <td width="98"> <p align="center"><strong>0.30</strong><strong>-</strong><strong>0.90</strong></p> </td> <td width="118"> <p align="center"><strong>1.20</strong><strong>-</strong><strong>1.80</strong></p> </td> <td width="59"> <p align="center"><strong>0.10</strong></p> </td> <td width="65"> <p align="center"><strong>0.25</strong></p> </td> <td width="39"> <p align="center"><strong>0.15</strong></p> </td> <td width="39"> <p align="center"><strong>0.05</strong></p> </td> <td width="39"> <p align="left"> </p> </td> <td width="33"> <p align="left"> </p> </td> </tr> </tbody> </table> <p align="left"> </p> <table border="1" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="664"> <p align="left"><br />2024合金的机械及物理性能</p> </td> </tr> </tbody> </table> <p align="left"> </p> <table border="0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="331"> <p align="left"><strong>抗拉强度</strong><strong>MPa </strong><strong> </strong><strong>470</strong><strong><br /></strong><strong>0.2%</strong><strong>屈服强度</strong><strong>MPa</strong><strong> </strong><strong> </strong><strong> </strong><strong>325</strong><strong> </strong><strong><br /></strong><strong>伸长率% </strong><strong>10</strong><strong><br /></strong><strong>疲劳强度</strong><strong> </strong><strong> </strong><strong> 105</strong><strong><br /></strong><strong>硬度</strong><strong>HB</strong><strong> </strong><strong>120</strong></p> </td> <td valign="top" width="331"> <p align="left"><strong>电导率</strong><strong>20°C</strong><strong> </strong><strong> </strong><strong> </strong><strong> </strong><strong> 30<br />20°C</strong><strong>电阻率</strong><strong>n</strong><strong> </strong><strong>.m </strong><strong> </strong><strong> 48</strong><strong><br /></strong><strong>弹性模量</strong><strong> </strong><strong> </strong><strong>68</strong><strong><br /></strong><strong>密度</strong><strong>KG.m-3 </strong><strong> </strong><strong> 2770</strong></p> </td> </tr> </tbody> </table>
