成批出售供应2A12铝合金

<div id="de-description-detail" class="de-description-detail fd-editor"> <p align="left"><span style="font-family: 宋体;"><span style="font-size: medium;">2A12合金铝的化学成分及用途：<br /><br />   2A12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></span></p> <p align="left"><span style="font-weight: bold;"> <tbody> <tbody> <tr> <td rowspan="2" width="6%" align="center" bgcolor="#0000cc"><span style="color: #ffffff;"><span style="font-size: medium;
