Founded in 1974
Sierra Alloys is located in Irwindale, CA with a primary focus on forged bar, flats and plate. After a long and successful history as a single-facility business, the company was acquired by Platte River Equity in 2011 and then combined with TSI Titanium (Derry, PA) to form PRV Metals Inc. The businesses were then acquired in 2019 by the current ownership group, Tinicum, and subsequently renamed as STS Metals Inc. (consisting of Sierra Alloys, TSI Titanium, Sierra Sheet & Plate and Brown-Pacific).
