C97® H14 – CuNi1Pb1P (C19150/C19160): High-Performance, Machinable Connector Alloy

Connectivity and free-machining alloy.

C97® (C19160) is part of Lebronze alloys’ large offer of machinable high performance alloys for connector applications, along with C98® and C99®. It is a heat-treated leaded nickel copper alloy with high electrical conductivity and machinability. C97® exhibits in particular high mechanical properties (high tensile strength, limited stress relaxation), which makes it suitable for high-range, harsh-environment connectors
