<ul>
<li>密度低，轻量化效果好</li>
<li>耐腐蚀性好，不用额外防锈</li>
<li>成型性好，冲压性能不错</li>
<li>导热导电性能好</li>
</ul>
<p dir="auto"><img src="https://forum.mj7.cn/assets/plugins/nodebb-plugin-emoji/emoji/android/274c.png?v=ri5u9ft48ro" class="not-responsive emoji emoji-android emoji--x" title=":x:" alt="❌" /> <strong>缺点</strong>：</p>
<ul>
<li>强度比钢材低，不能做高强度结构件</li>
<li>价格比碳钢高</li>
<li>粘模倾向比钢材大，模具要做处理</li>
</ul>
<h2>适用场景</h2>
<ul>
<li>新能源汽车电池壳体</li>
<li>轻量化结构件</li>
<li>消费电子屏蔽罩</li>
<li>电子产品外壳</li>
</ul>
<h2>冲压要点</h2>
<ul>
<li>模具表面要抛光，最好做氮化处理，减少粘模</li>
<li>冲压间隙比碳钢适当放大</li>
<li>拉伸时建议使用润滑油，提高表面质量</li>
<li>折弯注意回弹，模具要做补偿</li>
</ul>
