Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure	Goodwill and Intangible Assets Goodwill. Goodwill is related to our acquisitions of the Chandler, Arizona (Extrusion) facility and the Florence, Alabama facility and is included in the Fabricated Products segment. As of September 30, 2017, the carrying value of our goodwill was $18.8 million, reflecting an impairment in the quarter ended June 30, 2017. The carrying value was $37.2 million at both the beginning and the end of the year ended December 31, 2016. Several factors identified in a qualitative review in the quarter ended June 30, 2017 indicated that long-term demand for hard alloy extruded shapes produced at the Chandler, Arizona (Extrusion) facility was less than previously assumed. Such factors included: (i) reduced build rates of wide body commercial aircraft; (ii) continued low build rates for business jets; and (iii) additional substitution away from hard alloy extruded shapes in favor of composites, titanium and/or aerospace aluminum plate in the manufacture of commercial aircraft. After testing for goodwill impairment applying Level 3 inputs and a combination of an income approach using the estimated discounted cash flow and a market-based valuation methodology, we impaired the carrying value of the Chandler, Arizona (Extrusion) facility by $18.4 million to its fair value as of June 30, 2017. As this goodwill is deductible for income tax purposes, the deferred tax effects were included in the impairment charge and income tax provision. Intangible Assets. During the quarter ended September 30, 2016, we impaired one of our customer relationship intangible assets by $2.6 million. The non-cash impairment charge resulted from the loss of a customer during the quarter ended September 30, 2016. Other than the impairments discussed above, we identified no other indicators of impairment associated with the remainder of our goodwill and intangible assets during the nine months ended September 30, 2017 and September 30, 2016.
