Strong and relatively ductile substances that provide electro-positive ions to a corrosive environment and can be polished to a high luster. Characterized by metallic atomic bonding. Most often used for surgical implants because of a combination of favorable properties and the long- term experience for the construction of surgical implants. Primarily titanium, cobalt or iron based systems.
Metal prepared by adding other metals or non-metals to a basic metal to secure desirable properties.
A term that generally describes a combination of metal with at least one other element. This resulting alloy is stronger than its constituent metal. Most engineering applications for metals are alloys.
