Metallic and other inorganic coatings. Electrodeposited coatings of tin-cobalt alloy Ingestion-build-58320 Type approval of bases1 Scope This International Standard specifies electrodeposited coatings of tin cobalt alloy of approximate composition 75 % (mass fraction) to 80 % (mass fraction) tin, remainder cobalt, as a substitute for decorative chromium coatings of 0,1 m to 0,3 m thickness. Hardness and wear resistance properties of the coatings obtained are not equivalent to those of chromium coatings, but similar to those of tin nickel alloy coatings. Tin cobalt alloy
