Armco Credit Union was established in 1935 by a small group of Armco employees. This newly formed financial cooperative was the means by which some employees could save and other employees could borrow. We currently rank as the 3rd largest credit union in Western Pennsylvania with approximately $330 million in assets, while also exceeding 30,000 members. We are a state chartered credit union and are therefore governed by the banking laws of Pennsylvania. Deposits are federally insured by the National Credit Union Administration, an independent agency of the United States Government.
