Alloy Bellows manufactures and assembles custom bellows for the aerospace industry.  We work with a variety of materials, sizes and customization,  we provide a solution that fits the size, weight, pressure, temperature, and corrosion resistance properties to fulfill the application needs. Our product design and quality processes  are certified by our AS 9100 REV D certification, and validated by state of the art quality testing.

Bellows actuators convert pressure and/or temperature into motion. Volume compensator can balance pressure and or temperature differentials to ensure continuous, accurate operation of a system. Bellows are also manufactured for altimeters to sense pressure for critical applications. Bellows can also assist in the movement of air through the ducting system.


Our team of design, process, welding, and quality engineers has decades of experience developing bellows and welded solutions to meet your application’s demands.  We’ll work within your design parameters or collaborate with you to provide your optimum bellows solution while follow AS 9100 Rev D guidline. Our design group utilizes 3D CAD, Simulation, and empirical calculations based on the Expansion Joint Manufacturers Association (EJMA) standards as part of the design process.  This enables us to play “what-if” scenarios with the design and shorten the lead time for new product introduction (NPI).  Our project management approach for new product developments provides you with project updates as often as you need.
