The diameter of Udimet 520 springs that we could do range from 0.30 mm to 3.00 mm.

Our Udimet 520 springs come in a variety of surface finishes from bluing to clear or yellow zinc electroplating, electrolytic nickel, powder coating and zinc phosphate coating always executed by specialized subcontractors

At the end of the manufacturing and stress relief cycles, clients require different and very specific types of treatments in order to improve Udimet 520 spring performance. Terminal coil grinding, spring setting, internal and external tumbling, shot peen and vibration are the most common ones.

Udimet 520 is developed from earlier alloys such as UDIMET? alloy 500 and UDIMET? alloy 510 to provide slightly higher strength and greater stability over extended operating periods
