Ducommun is an American maker of electronic and structural parts for aerospace, defense and industrial customers. It calls itself a tier 2 supplier. That means it supplies parts to the larger firms that build aircraft and systems. The company serves commercial aircraft, military programs, space programs and industrial uses.

The company has a long history. The site says it was founded in 1849 by Charles Ducommun, who opened a hardware store in Los Angeles during the California Gold Rush. It calls itself the oldest company in California. It later supplied aircraft aluminum to early aerospace pioneers such as Lindbergh, Douglas and Lockheed.

Today the work falls into two core areas. Electronic Systems covers complex electronics made in high mix, low volume runs for uses where failure costs a lot. Skills include high-reliability interconnect systems, printed circuit board assemblies, and electronic, electromechanical and mechanical assemblies.

Structural Systems covers large, contoured parts and assemblies for aircraft and other uses. Its processes include stretch forming, thermal forming, chemical milling, precision fabrication, machining and finishing. The company also joins parts into sub-assemblies. The site lists assembly, bonding, forming, machining and tooling as separate capabilities.

Other product lines appear on the capabilities menu. These include VersaCore composite technology, RF solutions, motors and resolvers, human machine interface products, certified thermoplastics and lightning diversion systems. The company also names brands such as MAGSEAL and BLR Aerospace.

The company adds services around the work itself. These include new product introduction, supply chain strategy and program management. Its mission is to serve the aerospace and defense industry with engineered products, manufacturing and assembly, and aftermarket support. The site also states a set of core values, including honesty, respect, trust and teamwork.

News on the website shows recent recognition. BAE Systems named Ducommun its 2025 Vertical Launch Systems Supplier of the Year. The site also covers investor relations, supplier information, careers and an annual report. Visitors can use these pages to learn more.
