Beryllium Copper Bellows

Beryllium Copper Bellows Manufacturer | QBe2 Bellows
JK Bellows manufactures beryllium bronze bellows from QBe2 beryllium copper alloy for precision pressure sensing, measurement instruments, and mechanical control equipment. As part of our precision metal bellows range, these beryllium copper bellows feature hydroformed, thin-walled corrugated structures that provide elastic axial movement and pressure-responsive mechanical performance.
Our precision beryllium copper bellows are manufactured using hydroforming and age-hardening heat treatment. We supply QBe2 bellows in different diameters, wall thicknesses, convolution designs, and end configurations. Custom beryllium bronze bellows are also available for OEM manufacturers requiring specific dimensions, spring rates, axial strokes, and mounting connections.
