Why Join Armco CU?

government programs

2nd Largest Credit Union in Pittsburgh


$500M+ in Assets


40,000 Members


250 Sponsor Organizations

Armco CU is the 2nd largest credit union in the Pittsburgh area with over $500 million in assets, 40,000 members, 250 Sponsor Organizations and 4 locations in Butler, Mars, Karns City, and the BC3 Main Campus.

We are a not-for-profit financial cooperative, owned completely by our members. What that means to you is savings. Banks are responsible to stockholders and therefore higher fees and loan rates are necessary to provide income to those stockholders. At Armco CU, members are the owners. We do everything a bank can do, but we return our profits to our members in the form of lower loan rates, higher savings rates and lower/fewer fees.

We are a state-chartered credit union governed by the banking laws of Pennsylvania. Deposits are federally insured by the National Credit Union Administration (NCUA), an independent agency of the United States Government.

We will always put our member’s interests first by providing exceptional customer service, competitive savings & loan rates, and transparent products that are simple and easy to use.
