查看样本合金摘要数据表(PDF)自1952年以来,合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。以图表、图表和表格为特色,这些表格给出了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。这类Elkonite材料由一系列钨-银成分组成,钨含量在50-88 wt.%之间。钨在难熔金属中具有最高的强度和最高的熔化温度。这是决定触点抗电弧侵蚀和机械磨损能力的主要因素。 随着钨含量的增加,触点的强度、腐蚀和焊接电阻特性增加;电特性和热特性降低。应选择能够提供令人满意的温度和电流中断的最高耐火材料含量。
View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.This group Elkonite materials consists of a series of tungsten-silver compositions with the tungsten content ranging from 50-88 wt.%. Tungsten has the highest strength and the highest melting temperature of the refractory metals. This is the principal factor in determining resistance of a contact to arc erosion and mechanical wear. The strength, erosion, and weld-resistance characteristics of the contact increase with increasing tungsten content; the electrical and thermal characteristics decrease. The highest refractory content that will provide a satisfactory temperature and current interruption should be chosen.
