Material Properties

Metal : pure metals often are quite weak and may have many undesirable properties. In order to avoid this drawback ,metals are mixed together to produce alloys. So, an Alloy is a composite material. Most of orthopaedic materials in use are alloys. Examples include 316 L Stainless steel, Titanium alloy, Cobalt-chrome etc. 

Stainless steel : alloy of iron, chromium, nickel. 316 L has chromium and is corrosion resistant. This is important as implants inside the body are exposed to the very corrosive influence of saline. It is still rather susceptible to corrosion and has low fatigue strength.
