Business Combinations [Abstract]
Acquisitions	Acquisitions In April 2017, the Company, through its wholly-owned subsidiary Apollo Aerospace Components, completed the acquisition of Aero-Missile Components Inc. (“AMC”) for $10.5 million in cash. AMC is a supply chain management business providing high-quality specialty fasteners and other components to the defense and aerospace markets. The results of AMC are included in the Supply Technologies segment from the date of acquisition. The allocation of the purchase price is subject to finalization of the Company's determination of the fair value of assets acquired and liabilities assumed as of the acquisition date. The Company has not yet finalized its analysis of the fair value of inventory and certain other assets and liabilities. The final allocation is expected to be completed as soon as practicable but no later than twelve months after the acquisition date. As of June 30, 2017, the Company recorded goodwill of $2.2 million related to this transaction. In December 2016, the Company acquired all the outstanding capital stock of GH Electrotermia S.A. (“GH”), headquartered in Valencia, Spain, for $23.4 million in cash (net of $6.3 million cash acquired), plus the assumption of $13.9 million in debt. The allocation of the purchase price at June 30, 2017, which is materially unchanged from December 31, 2016, is subject to finalization of the Company's determination of the fair value of assets acquired and liabilities assumed as of the acquisition date. The Company has not yet finalized its analysis of the fair value of property, plant and equipment; intangible assets; noncontrolling interests; deferred taxes and certain other assets and liabilities. The final allocation is expected to be completed as soon as practicable but no later than twelve months after the acquisition date. In addition, the purchase agreement stipulates potential contingent consideration of up to $2.1 million based on achievement of certain EBITDA targets for 2016 and 2017. The EBITDA target for 2016 was not achieved. The estimated fair value of the contingent consideration, valued using level 3 inputs, was approximately $1.1 million as of June 30, 2017 and December 31, 2016.
