· Er8Co17

Er8Co17 is a cobalt-based alloy containing erbium as a significant alloying addition, belonging to the family of rare-earth-modified cobalt systems. This material is primarily investigated for high-temperature structural applications and magnetic devices where erbium addition improves specific mechanical or magnetic properties compared to conventional cobalt alloys. Er8Co17 systems are typically found in research and specialized industrial contexts rather than commodity applications, making them relevant for engineers developing advanced aerospace components, high-performance magnetic materials, or extreme-environment structures where the rare-earth modification provides advantages in creep resistance, oxidation behavior, or functional magnetic properties.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
