For nearly 50 years, Cleveland-based Alcon Industries has produced heat- and corrosion-resistant alloy castings and fabrications, with in-house engineers and craftsmen turning drawings, existing parts, or ideas into production components. Its foundry is particularly known for custom furnace parts and other demanding industrial components, serving customers around the world from Northeast Ohio. Alcon also operates an alloy buyback program that gives customers credit for usable scrap toward future orders.
