What are light bulb bases made of?

Light Bulb screw in bases are made of three different materials: Aluminum, Brass and Nickel Plated Brass. The most economical way to manufacture these is with aluminum but it isn't intended for bulbs used in certain situations.

Any of the long life bulbs or ones that come in contact with outdoor elements(or humidity), should be made of brass or nickel plated brass as these are corrosive resistant materials. You should also choose a bulb with these materials in the base if you have a problem with the base sticking in the socket or where it's difficult to replace the light bulb.
