Four popular bicycle frame materials are steel, aluminum, titanium and carbon fiber. Beryllium, Metal Matrix Composites and other materials have so far demonstrated limited practicality in bicycle frames. Mysterious and seemingly miraculous beryllium is one-third the weight of aluminum and six times as stiff as steel.his is another reason to look for metal frame parts (such as dropouts) that are made of titanium rather than aluminum if you are shopping for a carbon fiber bike. Discontinuity of materials can create stress-risers where the carbon fiber meets the other material. The stress-risers can lead to failure.
Except for a few, where in aluminum is used to give light weight to the body. But the main frame work and other parts like pistons, wires, wheel bearings are made of iron. Grey cast iron is used in making engine piston cylinder cases, gear boxes and other tools. While white cast iron is used to make bearings. Again here iron is preferred for its toughness, ability to withstand high temperature of engine etc.
