Because aluminum is lightweight and strong, aluminum die casting parts are used for automotive, car or automobile applications. Aluminum Auto Parts are necessary to reduce the weight of the automobile so cars can get better fuel economy. The OEM (Original Equipment Manufacturers) or Major auto manufactures love aluminum die casting for their auto parts because several thousand parts can be produced a year at a very low cost. Some OEM auto makers have their own die casting plants to produce their auto parts. Others contract with Jobshop die casters to produce their aluminum auto parts. Aftermarket auto parts manufacturing companies are companies that produce auto parts to be sold in stores. Aftermarket auto parts manufacturers use die cast aluminum auto parts because they are inexpensive to produce and are typically better quality than other aluminum part manufacturing processes. Prototype parts or Custom Parts or OEM parts and Aftermarket Auto parts come in various locations, such as:

Aluminum Die Casting Handles
Car door handles have been die cast as well as the aluminum handle hardware that opens the console and the trunk of the car.

Aluminum Valve Covers
Valve covers are very commonly die cast in aluminum because they hold a chrome look without using chrome plating. Valve covers need to diffuse heat and aluminum is a great conduit for thermal transfer.

Aluminum Wheels
Many wheels are thought to be made from magnesium but are in fact made from aluminum. Aluminum is very strong and can be polished to a high luster.

Aluminum Brackets
Many of the engine components are held into place using die cast aluminum brackets. The brackets hold the alternator and air conditioner into place.
