The theory was simple, bronze & brass elongation was not.
With only 40–50 % elongation versus stainless steel’s 60 %+, achieving uniform wall thickness below 0.10 mm and flawless convolutions demands absolute control over hydraulic pressure, lubrication, and raw material consistency—any deviation risks thinning, cracking, or early fatigue failure.
Precision without compromise. Performance without limits.
Our automatic quick-hydroforming delivers mirror-smooth, scratch-free bronze & brass bellows with perfectly uniform wall thickness, full material ductility, seamless construction, and zero-leak reliability straight from the machine – every part, every time.
Key Features of Bronze and Brass Bellows
Ultra-uniform wall thickness (±0.005 mm tolerance) thanks to fully automated pressure profiling
No heat-affected zone or work-hardening from welding – 100 % seamless, cold-formed convolutions retain full alloy ductility and conductivity
Faster cycle times (30–90 seconds per bellows) – shorter lead times and lower cost even for small batches
Consistent grain structure and spring rate – every bellows performs identically, critical for switchgear contacts and vacuum interrupters
No lubricant residue inside – clean-room compatible straight from the machine, ideal for medical, cryogenics, and UHV applications
Higher convolution depth-to-thickness ratio than traditional punch-formed bronze/brass – more stroke in less axial space
Immediate helium leak testing in-line – every single part verified to 1×10⁻¹⁰ mbar·l/s before it leaves the press
Hanovix hydroformed bronze & brass bellows are the go-to solution for engineers tackling corrosion in industrial valves, high-vacuum seals, mechanical actuators, and pressure gauges where electrical conductivity and fatigue resistance can't be compromised.
All products manufactured in-house to the same rigorous Hanovix standards of precision, cleanliness and reliability.
