Pennex Aluminum Company


Pennex Aluminum has become a leading provider of extruded aluminum solutions for automotive applications by offering unparalleled value add services. What started as an extrusion based operation has evolved to include aluminum billet production, technical support services, wide ranging fabrication capabilities and a world class quality assurance system. This combination of in-house capabilities and systems rivals that of companies many times our size but without all the issues common with large organizations. It’s what we refer to as the Pennex Advantage: large company capabilities and expertise with small company service and attention to detail. Once you have experienced the Pennex Advantage for yourself, you will find it difficult to work with anyone else!
