Union Minerals and Alloys Corporation is a United States corporation that ran a shipbreaking operation. In the 1960s and 1970s it purchased from the United States Maritime Administration many surplus U.S. Navy and U.S. Merchant Marine ships from World War II for scrapping.

The company scrapped USS Siboney,[1] an escort carrier, which featured in the ending of the 1973 Clint Eastwood movie Magnum Force while it was moored in Suisun Bay, California.
