Cobalt - Wikipedia
网页Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
Cobalt Alloys - an overview | ScienceDirect Topics
网页Cobalt alloys primarily consist of cobalt and chromium mixed with small amounts of carbon, iron, nickel, silicon, manganese, or molybdenum [45]. They serve as excellent choices for biomaterials due to their magnetic properties, corrosion, and wear resistance, long term stability, and solidity [39] .
Cobalt-chrome - Wikipedia
网页Cobalt-chrome or cobalt-chromium (CoCr) is a metal alloy of cobalt and chromium. Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants. [1]
