Alloy is an unincorporated community in Fayette County, West Virginia, United States. Alloy is located along the Kanawha River and U.S. Route 60, 5miles southwest of Gauley Bridge. Alloy was originally known as Boncar (anagram of carbon) until the mid-1930s. Both the original placename and the current placename refer to the ferroalloy plant[1] that still operates here (producing about 30% of all the silicon metal in North America). The metals plant was originally the Electro Metallurgical Co.; a unit of Union Carbide and Carbon Corporation. Alloy has a post office with ZIP code 25002.[2]
