Declafor® 1015 spinodal alloy


Declafor® 1015 is a range of Copper-Nickel-Tin (CuNi7.5Sn5Te; UNS C72700) alloys designed and produced by Lebronze alloys (ex. CLAL).

Its complex manufacturing process includes solution annealing, work hardening and spinodal hardening to obtain very high mechanical and physical properties.

Declafor® can be a substitute to Beryllium Copper and leaded Beryllium Copper for some applications. It is available in wires, rods as well as strips and sheets.

Mechanical and processing advantages

Declafor® 1015 exhibits very high mechanical properties, such as good polishing ability and surface quality.

Declafor® 1015 exhibits machinability comparable or superior to CuBe2Pb, thanks to Tellerium addition, making it suitable for applications such as horology microcomponents and coaxial connectors for telecommunications.

Declafor® products high elasticity and formability allow light and durable designs: for example, it is a material of reference in the eyewear industry.

High physical properties

Declafor® exhibits high conductivity, very good corrosion resistance, magnetic properties and shielding effectiveness.

It is extensively used in the electronics industry, including aerospace systems, for applications such as coaxial connectors and electrical spring contacts.

A recyclable and environment-friendly solution

Declafor® materials are beryllium-free, lead-free and cadmium-free, and are compliant with REACH and RoHs regulations.

Lebronze alloys is committed to offer recyclable solutions, to enhance their environmental performance during manufacturing and also during the whole components life cycle.
