ZeST®: performance materials for a lead-free future
Lebronze Alloys announces the launch of ZeST®, a next-generation family of fully lead-free turning alloys designed to help electronics, medical-device, connector and precision industries transition to more responsible materials, without compromising performance.
Engineered for demanding machining environments, all ZeST® alloys deliver fast cutting speeds, controlled chip-breaking, and steady tool life, while remaining fully REACH & RoHS compliant.
ARCAP ZeST®
The lead-free evolution of ARCAP® AP1D, retaining its signature non-magnetism, excellent corrosion resistance, and high dimensional stability. Ideal for luxury watchmaking, electronics, and medical precision parts. Recycled content: at least 90%.
BZ4 ZeST®
The next-generation alternative to BZ4 (C54400), developed for high-performance connector systems. Clean chip-breaking, low friction, and reliable tolerances even in complex machining. Recycled content: 92%.
C97 ZeST®
The lead-free version of C97® (C19160), combining high electrical conductivity with high mechanical strength. Designed for aerospace and electronic applications where signal integrity and machining consistency are critical.
Declafor ZeST®
A modern substitute for leaded beryllium copper, offering high strength, resilience, and excellent machinability for miniature, tight-tolerance parts in watchmaking and connectors. Recycled content: 99%.
Engineered without lead. Built to perform.
A responsible and high-performance offer
With ZeST®, Lebronze Alloys delivers a complete range of lead-free, high-performance materials, each designed to combine precision, machinability, and responsible sourcing. The future of lead-free precision starts now.
