Alloys

Health / Dentistry / Alloys: 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.
