Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying consolidated financial statements of Materion Corporation and its subsidiaries (referred to herein as the Company, our, we, or us) contain all of the adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods reported. All adjustments were of a normal and recurring nature. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company's 2021 Annual Report on Form 10-K. The interim period results are not necessarily indicative of the results to be expected for the full year.
Business Combinations	Business Combinations: The Company records assets acquired and liabilities assumed at the date of acquisition at their respective fair values. Any intangible assets acquired in a business combination are recognized and reported apart from goodwill. Goodwill represents the excess purchase price over the fair value of the tangible net assets and intangible assets acquired in a business combination. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred. The amounts reflected in Note B of the consolidated financial statements are the results of a preliminary purchase price allocation and will be updated upon completion of the final valuation. The Company is required to complete the purchase price allocation within 12 months of the acquisition date. If such completion of the allocation results in a change in the preliminary values, the measurement period adjustment will be recognized in the period in which the adjustment amount is determined.
New Accounting Guidance Issued and Not Yet Adopted	New Pronouncements Adopted: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance is intended to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is available immediately and may be implemented in any period prior to the guidance expiration on December 31, 2022. The Company has applied this guidance in accounting for the interest rate swap discussed in Note N. Any additional reference rate reform impacts will be accounted for in accordance with ASU 2020-04. New Accounting Guidance Issued and Not Yet Adopted: In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832). ASU 2021-10 is intended to increase transparency related to governmental assistance by requiring entities to disclose the types of government assistance, the entity's accounting for government assistance, and the effect of government assistance on an entity's financial statements. This new guidance is effective for all entities for annual reporting periods beginning after December 15, 2021. The Company is in the process of evaluating the impact of the guidance on its annual disclosures. No other recently issued or effective ASUs had, or are expected to have, a material effect on the Company's results of operations, financial condition, or liquidity.
Revenue	Net sales consist primarily of revenue from the sale of precious and non-precious specialty metals, beryllium and copper-based alloys, beryllium composites, and other products into numerous end markets. The Company requires an agreement with a customer that creates enforceable rights and performance obligations. The Company generally recognizes revenue in an amount that reflects the consideration to which it expects to be entitled upon satisfaction of a performance obligation by transferring control over a product to the customer. Control over a product is generally transferred to the customer when the Company has a present right to payment, the customer has legal title, the customer has physical possession, the customer has the significant risks and rewards of ownership, and/or the customer has accepted the product. Transaction Price Allocated to Future Performance Obligations: Accounting Standards Codification 606, Revenue from Contracts with Customers, requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied at April 1, 2022. Remaining performance obligations include non-cancelable purchase orders and customer contracts. The guidance provides certain practical expedients that limit this requirement. As such, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.
