Formed Metal Bellows Manufacturer

For over 40 years, Ameriflex has been a leader in the manufacturing of metal bellows for the vacuum electronics industry. Our bellows and expansion joints are designed to absorb and reduce vibration and relieve structural stress from pressurized environments, extreme temperatures, and other variables. We specialize in thin-wall bellows and offer prototyping as well as low-volume and high-volume production.

Our metal bellows are made to meet customer requirements for movement, pitch, bend radius, environmental conditions, and a variety of additional design considerations. Our expert engineering staff can design metal bellows to meet your needs, help with design issues or we can produce custom metal bellows to your specifications. With in-house tool-making capabilities, Ameriflex can create custom metal bellows that match your exact specifications.

We produce metal bellows in sizes ranging from 0.25” I.D. through 48” I.D., and wall thicknesses from 0.002” through 0.056” in either single-ply or multi-ply configurations. Our metal bellows are manufactured from several metals, including stainless steel, Inconel, Hastelloy, titanium, Monel, phosphorous bronze, copper, and brass. We also have a large stock of DFARS-compliant material on hand.
