Loss Contingency [Abstract]
Contingencies	Contingencies Materion Brush Inc., one of the Company's wholly-owned subsidiaries, is a defendant from time to time in proceedings where the plaintiffs allege they have contracted chronic beryllium disease (CBD) or related ailments as a result of exposure to beryllium. The Company will record a reserve for CBD or other litigation when a loss from either settlement or verdict is probable and estimable. Claims filed by third-party plaintiffs may be covered by insurance subject to deductibles which vary based on when the exposure occurred. Reserves are recorded for asserted claims only, and defense costs are expensed as incurred. One CBD case that was outstanding at the end of the second quarter of 2016 was settled during the third quarter of 2016. The settlement of this case has been fully reflected in the Company's financial statements and is not material to the Company's consolidated financial statements. One CBD case that had been on appeal was remanded to the trial court and was outstanding as of the end of the third quarter of 2016. The Company does not expect the resolution of this matter to have a material impact on the consolidated financial statements. The Company has an active environmental compliance program and records reserves for the probable cost of identified environmental remediation projects. The reserves are established based upon analyses conducted by the Company’s engineers and outside consultants and are adjusted from time to time based upon ongoing studies, the difference between actual and estimated costs, and other factors. The reserves may also be affected by rulings and negotiations with regulatory agencies. The undiscounted reserve balance was $6.0 million at September 30, 2016 and $5.7 million at December 31, 2015. Environmental projects tend to be long term, and the final actual remediation costs may differ from the amounts currently recorded.
