Alloy K500 (UNS N05500)

Alloy K-500是一种析出硬化镍铜合金。 虽然Langley Alloys可在所有条件下供应Alloy K-500，但主要是在热加工和析出处理条件下供应材料，从而在所有尺寸范围内提供最佳的高强度和延性组合。 增强的属性得益于在镍铜基质中添加了铝和钛，并在受控条件下加热，以便让“ϒ”Ni3 (Ti, Al)颗粒析出到整个基体中。 用于影响析出的热处理通常被称作时效硬化或老化。

这种合金可在许多环境中提供出色的耐腐蚀性，包括海水、氢氟酸、硫酸和碱。 它经确认可耐受酸气环境并被列入了NACE MR1075。 得益于在高速海水中的极低腐蚀率和高强度，它非常适用于不流动或缓慢流动海水环境中的船用轴。虽然可能会结垢并造成点蚀，但在发生极快的最初点蚀后，点蚀速度便会慢下来。

通过电渣精炼(ESR)工艺对Alloy K-500进行精炼，确保供应最干净和最优质的材料。 提升的合金纯度降低了存在硬质非金属夹杂物的可能性，否则这种夹杂物会增大加工难度，延长加工时间，还会最终导致零件失效。 它还具有低磁导率，在低至-150°F (-101°C)的温度下也不会产生磁性。
