摘要： A cobalt-based alloy, a wearable article, and a preparation method for a metal product. The cobalt-based alloy consists of the following chemical components in percentage by weight: at least about 50% cobalt, at least about 20% chromium, at least about 0.1% molybdenum, and the remainder being one or more of the groups consisting of the following chemical components: manganese, vanadium, tungsten, nickel, titanium, iron, aluminum, lanthanum, tantalum, iridium, cerium, phosphorus, carbon and inevitable impurities. The cobalt-based alloy has the properties of high ductility, deformability and hardness, and is therefore particular suitable for being made into the wearable article.
