PerforMet® Alloy for Automotive and EV Components

PerforMet®合金是一种镍硅化合物强化的青铜材料，专为汽车动力系统及电动汽车（EV）应用优化设计。其结合高强度、高导热性、耐摩擦、耐磨和耐腐蚀特性，可在高功率密度发动机中承受更高压力和温度，从而提升动力与扭矩输出，同时降低燃油消耗。

在传统内燃机及替代燃料动力系统中的应用中，PerforMet®合金用于制造进排气阀座、气门导管和活塞环等部件，可有效导出关键组件的热量，减少局部过热风险，提升发动机效率、性能及长期可靠性。这些优势对降低排放、维持动力与车辆性能至关重要。

在电动汽车（EV）中的应用中，驱动系统微型化可节省重量与空间，但会加剧热压问题并产生轴向推力。高导热性的PerforMet®合金能有效管理热量与压力，显著降低车内噪声（NVH）。例如，采用该材料制造差速器轴承时，因其卓越的耐磨性和自润滑性，噪声可降低10分贝。
