The flat wire design of wave springs offers the best balance of size and spring force in many applications, and they offer considerable advantages over their more common counterparts. One of the main reasons wave springs are specified in design is the impressive force-to-work height ratio, as they can produce the same or even greater forces as coil springs, whose work heights are up to twice as large. In static applications, a wave spring will typically need just 50 percent of coil springs' work height to deliver an equivalent force. In dynamic applications, the work height advantage is approximately 30 percent lower than in static applications, but still substantial. Wave springs can also save space in the radial direction, compared with using disc or coil springs with larger diameters.
