<h2>概述</h2>
<p dir="auto">C5210 是高锡含量磷青铜，含锡 8 ~ 11%，比 C5191 锡含量更高，强度弹性更好，适合高端精密弹片。</p>

<ul>
<li>强度弹性比 C5191 更高</li>
<li>耐磨耐疲劳性能更好</li>
<li>弹性稳定性好，长期使用弹性衰减慢</li>
<li>耐腐蚀性能好</li>
</ul>

<ul>
<li>价格比 C5191 更贵</li>
<li>硬度高，对模具磨损更大</li>
<li>冲压回弹更大，模具补偿要求更高</li>
</ul>
<h2>适用场景</h2>
<ul>
<li>高端精密连接器弹片</li>
<li>微型开关弹片</li>
<li>继电器高端弹片</li>
<li>要求高弹性长寿命的冲压零件</li>
</ul>
<h2>冲压要点</h2>
<ul>
<li>回弹比 C5191 更大，模具必须做精确回弹补偿</li>
<li>模具必须用耐磨模具钢（DC53/Cr12MoV），淬火硬度要够</li>
<li>冲压间隙要合适，减少模具磨损</li>
<li>建议分步冲压，降低一次变形量，减少开裂</li>
</ul>
