This cobalt-chromium-nickel alloy offers a combination of high strength, ductility, and good mechanical properties, is hardenable, has excellent fatigue resistance, is corrosion-resistant, and non-magnetic. Phynox is also known as Elgiloy, Conichrome, and Alloy 3J21. Thus, this mainspring belongs to the category of modern \"white metal\" mainsprings, which, in contrast to classic blue carbon steel, are rust-free and practically unbreakable, and do not lose their elasticity as easily. \u003cspan class=\"inline-flex\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eCitizen marketed its original mainsprings – similar to Swiss manufacturers with \"Nivaflex\" – consciously under the premium alloy name. It is therefore a \u003cstrong\u003eCitizen original part\u003c\/strong\u003e, not an aftermarket replacement.
