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.

QBe2 is a high-strength copper alloy containing approximately 2% beryllium. Its elastic properties, formability, and response to age-hardening treatment make it suitable for manufacturing precision elastic components.
Our QBe2 beryllium copper bellows combine the mechanical properties of beryllium copper with thin-walled corrugated structures for controlled axial movement. These characteristics are important for pressure measurement, instrument control, and repeated mechanical actuation.
