· CoBW

CoBW is a cobalt-based binary or ternary alloy system combining cobalt with tungsten and boron. This material family is primarily explored in research and specialized industrial settings for applications requiring high hardness, wear resistance, and thermal stability—particularly in tool materials, wear-resistant coatings, and high-temperature structural components where conventional steel or nickel-based superalloys are insufficient.

Export Control

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.
