Below is a list of Alloy Castings manufacturers from Muskegon, Michigan. Alloy castings are die cast products that are formed out of metal alloys. During this process, the alloys, which are usually non-ferrous (not containing iron) are heated until molten and injected into a mold, where they solidify and take a certain shape to form a vast array of different parts and products for the automotive, aerospace, construction, commercial product manufacturing and many other industries. They may be as complex as a vehicle's transmission housing or as simple as a door handle.
