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”), formerly known as Signature Group Holding, Inc., 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 our existing operations described below. Our current business strategy seeks to leverage our public company status, considerable United States (“U.S.”) federal net operating tax loss carryforwards (“NOLs”) and the experience of our executive management team to acquire operating businesses at prices and on terms that are aligned with our growth plans. 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 our primary operating business. 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”). The Real Alloy Business, operating under Real Alloy Intermediate Holding, LLC (“Real Alloy Parent”) through its wholly owned subsidiary Real Alloy Holding, Inc. (“Real Alloy”), is a global leader in third-party aluminum recycling. 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, steel and durable goods, aerospace, and building and construction industries. Real Alloy processes scrap aluminum and by-products, and delivers recycled metal in solid or molten 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-four facilities strategically located throughout North America and Europe and, as of June 30, 2016, had approximately 1,700 employees. Other significant milestones achieved in 2015 included: on April 21, 2015, our common stock began trading on the Nasdaq Stock Market (“NASDAQ”) under the symbol “RELY” as part of the NASDAQ Global Select Market; on May 28, 2015, our stockholders approved an amendment to our charter to change our name to Real Industry, Inc.; and in June 2015, Real Industry became a member of the Russell Global^®, Russell 2000^® and Russell Microcap^® indexes. As a result of the transformative nature of the acquisition and divestiture activities described above, our operations for the six months ended June 30, 2015, which included the results of operations of Real Alloy for approximately four months, are not comparable to the results of operations for the six months ended June 30, 2016, in which Real Alloy is reporting results for the full six months in this Quarterly Report on Form 10-Q (the “Report”). See Note 11—Segment Information for additional information about our reportable segments. The assets and liabilities and results of operations of NABCO, prior to its divestiture, are included in discontinued operations for all periods presented as a result of its sale in the first quarter of 2015, and the strategic shift in the Company’s operations. Discontinued operations also includes certain assets and liabilities related to the former businesses of our subsidiary SGGH, LLC (“SGGH”), then known as Fremont General Corporation (“Fremont”) and its primary operating subsidiary, Fremont Investment & Loan (“FIL”). See Note 12—Discontinued Operations for additional information about our discontinued operations.
