Canted Coil Springs FAQs
What is a canted coil spring and how does it differ from a standard compression spring?
A canted coil spring uses coils wound at an angle rather than stacked perpendicular to the spring axis, which creates multiple simultaneous contact points along the spring's circumference or length. This geometry delivers consistent electrical conductivity, controlled and predictable loading forces, and effective EMI/RFI shielding in a compact footprint that a standard round-wire compression spring cannot replicate. The canted geometry also provides a relatively flat force-deflection curve over a wide deflection range, making canted coil springs valuable in both static sealing and dynamic engagement applications where consistent force across a range of positions is required.
What industries use canted coil springs?
Canted coil springs serve a broad range of high-technology industries: aerospace and defense (electrical connectors, EMI/RFI shielding, locking ring mechanisms), medical devices (surgical instruments, implantable device connectors, endoscopic equipment), automotive and electric vehicle systems (battery pack connectors, high-current charging contacts, drivetrain sensors), oil and gas (downhole instrument connectors, subsea electrical penetrators), semiconductor and electronics manufacturing (wafer handling contacts, burn-in socket springs), renewable energy (wind turbine electrical contacts, solar inverter connectors), and industrial robotics and automation (end-of-arm tool electrical contacts, encoder connections).
What materials are canted coil springs available in?
Canted coil springs can be manufactured in stainless steel (302 or 316 for general industrial and electronic applications), Inconel and other high-performance nickel alloys (for high-temperature or highly corrosive environments), beryllium copper (where high conductivity and non-magnetic properties are required), Elgiloy (for medical and extremely corrosive applications), and other specialty alloys depending on the electrical conductivity, corrosion resistance, temperature, and fatigue life requirements of the specific application.
How do canted coil springs provide EMI/RFI shielding?
The angled coil geometry creates continuous, multi-point metal-to-metal contact around a gap or seam—closing off the electromagnetic leakage path that would otherwise allow interference to pass in or out of an enclosure. The multiple simultaneous contact points around the spring's perimeter ensure consistent shielding effectiveness even with minor dimensional variation in the mating surfaces, providing more reliable shielding than single-point or intermittent contact designs. This makes canted coil springs a standard choice for shielding sensitive electronics in aerospace cockpit assemblies, defense equipment enclosures, and semiconductor processing chambers.
Can canted coil springs be customized for specific load and deflection requirements?
Yes. Coiling Technologies' engineering team works directly with customers to determine coil angle, wire diameter, material, and spring outer dimensions to hit specific load, deflection, and operating cycle-life targets. Whether the application is a static seal, an intermittent-engagement connector, or a high-cycle dynamic contact, the spring geometry can be optimized for consistent load characteristics across the specified deflection range.
Are canted coil springs suitable for high-cycle dynamic applications?
Yes. The distributed load across multiple contact points reduces localized surface stress and wear compared to single-point contact designs, which extends component life in both static sealing and dynamic, repeated-engagement applications such as electrical connectors and locking ring mechanisms. For high-cycle electrical contact applications in test and measurement or electronics manufacturing equipment—where springs may cycle millions of times—canted coil spring geometry is well suited to providing reliable contact force across the full service life.
