Niclafor® 1000 TH4 – High‑Strength CuNi9Sn6 Alloy for Heavy‑Duty Applications

Niclafor® 1000 is a range of Copper-Nickel-Tin (CuNi9Sn6) alloys designed and produced by Lebronze alloys (ex. CLAL).

Mechanical advantages: Niclafor® 1000 exhibits very high mechanical properties, such as Tensile Strength and Yield Strength above 1,000 MPa (145 ksi) depending on temper, even at high temperatures. It has an excellent fatigue resistance and low friction, making it suitable for heavy duty applications.

High physical properties: Niclafor® exhibits high conductivity, very good corrosion resistance, magnetic properties and shielding effectiveness.

A recyclable and environment-friendly solution: Niclafor® materials are beryllium-free, lead-free and cadmium-free, and are compliant with REACH and RoHs regulations.
