Formally The Penn Brass & Copper Co. of Erie, Pennsylvania, Penn was founded in 1923 and acquired by The Marmon Group of companies in 1971. With the appliance and automotive industries using increasing amounts of aluminum in lieu of copper, the future was bright for aluminum. Only months after The Marmon Group purchase, out-dated copper tube production was halted, and experienced metallurgical and mechanical engineers were hired to develop more aluminum tube sizes and alloys. In 1977, the company changed its name to Penn Aluminum International, Inc. |
