牌号：BFe5-1.5-0.5

BFe5-1.5-0.5铁白铜 是一种含铜、镍、铁、锰等元素的合金，具有优异的耐腐蚀性、机械性能和加工性能，广泛应用于 海洋工程 、 电力 、 化工 等领域。 ‌
耐温性能
在300℃以下温度区间，其抗拉强度保持420MPa以上，硬度（HV）稳定在120左右，弹性模量维持在10GPa。经300℃×1000小时长期时效处理后，晶界无明显析出相，热循环500次无裂纹。 ‌
机械性能
抗拉强度≥440MPa，屈服强度≥180MPa，延伸率≥30%，布氏硬度110-150。适合制造高强度、高耐磨的机械零件，如轴承、齿轮等。 ‌
耐腐蚀性
海水腐蚀速率≤0.02mm/年，盐雾测试≥500小时无腐蚀。在含氯化物、海水等腐蚀性环境中表现突出，适用于船舶零部件、化工设备等。 ‌
加工性能
冷加工性极好，热加工性良好，可制成棒材、板材、管材等。加工过程中需注意避免变形超过80%。 ‌

化学成分

BFe5-1.5-0.5铁白铜的化学成分如下：
‌铜（Cu）‌：余量（主体成分） ‌
‌镍（Ni）‌：38%-41% ‌
‌铁（Fe）‌：4.5%-5.5% ‌
‌锰（Mn）‌：1%-2% ‌
‌碳（C）‌：≤0.05% ‌
‌硅（Si）‌：≤0.1% ‌
‌铅（Pb）‌：≤0.02% ‌
‌锌（Zn）‌：≤1.0% ‌
补充说明
镍含量范围存在两种表述：
一种表述为38%-41%（主流数据） ‌
另一种表述为4.8%-6.2%（可能与合金元素计算方式有关） ‌
铁含量需控制在≤2%以避免腐蚀开裂，锰的添加可提升加工性能。 ‌
