Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business and Operations	NOTE 1—BUSINESS AND OPERATIONS Real Industry, Inc. (“Real Industry,” the “Company,” “we,” “us” or “our”), is a Delaware holding company that operates through its operating subsidiaries. Management expects to grow the Company through acquisitions, as well as through organic efforts within existing operations described below. Our current business strategy seeks to leverage our public company status, $916.0 million of United States (“U.S.”) federal net operating tax loss carryforwards (“NOLs”) and the experience and focus of our executive management team to acquire operating businesses at prices and on terms that we believe will create a sustainably profitable enterprise. During the first quarter of 2015, the Company underwent a considerable transformation. On January 9, 2015, we completed the sale of North American Breaker Co., LLC (“NABCO”), previously the primary business within our former Industrial Supply segment. On February 27, 2015, we acquired the global recycling and specification alloys business (the “Real Alloy Business”) of Aleris Corporation (“Aleris”) (the “Real Alloy Acquisition”). A portion of the proceeds from the sale of NABCO were used to fund the Real Alloy Acquisition. The Real Alloy Business, operating as Real Alloy Holding, Inc. (“Real Alloy”), is a global leader in third-party aluminum recycling, which includes the processing of scrap aluminum and by-products and the manufacturing of wrought, cast and specification or foundry alloys. Real Alloy offers a broad range of products and services to wrought alloy processors, automotive original equipment manufacturers, and foundries and casters. Real Alloy’s customers include companies that participate in or sell to the automotive, consumer packaging, aerospace, building and construction, steel, and durable goods industries. Real Alloy processes aluminum scrap and by-products and delivers recycled metal in liquid or solid form according to customer specifications. Real Alloy’s facilities are capable of processing industrial (new) scrap, post-consumer (old/obsolete) scrap, and various aluminum by-products, providing a great degree of flexibility in reclaiming high-quality recycled aluminum. Real Alloy currently operates twenty-seven facilities strategically located throughout North America and Europe. On November 1, 2016, Real Alloy completed the purchase of select assets of Beck Aluminum Alloys Ltd. (“Beck Alloys”), including an investment in an affiliated trading business (“Beck Trading”). The three acquired Beck Alloys facilities primarily produce high-purity foundry alloys from aluminum scrap to supply the automotive, wheel and recreational equipment casting industries. Our focus is supporting the performance of Real Alloy, as well as evaluating potential acquisition opportunities. We seek to acquire significant ownership interests in businesses with talented and experienced management teams, strong margins, and sustainable competitive advantages. We regularly consider acquisitions of businesses that operate in undervalued industries, as well as businesses that we believe are in transition or are otherwise misunderstood by the marketplace. Post-acquisition, we plan to operate our acquired businesses as autonomous subsidiaries. We anticipate that we will continue to use our common stock, preferred stock and other securities to pursue value-enhancing acquisitions and leverage our considerable tax assets, as well as support the growth needs of our existing operating segments, as necessary.
