Subsequent Events [Abstract]
Subsequent Events	18. Subsequent Events Dividend Declaration. On January 14, 2025, we announced that our Board of Directors declared a quarterly cash dividend of $0.77 per common share. As such, we paid approximately $12.7 million (including dividend equivalents) on February 14, 2025 to stockholders of record and the holders of certain restricted stock units at the close of business on January 24, 2025. Collective Bargaining Agreement Renewal. In February 2025, the Company and the USW ratified new five-year collective bargaining agreements covering approximately 1,000 employees primarily located at our Trentwood and Newark facilities, and a separate agreement with the USW for another operation related to Trentwood. While the term of the current agreements ends on September 30, 2025, the new agreements will take effect upon expiration of the current agreements with a term ending on September 30, 2030. The entry into the new collective bargaining agreements did not have an impact on the Company’s consolidated financial statements for the year ended December 31, 2024.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
