Copper-Nickel-Tin Alloys
Spinodal copper-nickel-tin alloys deliver beryllium-free spring, bearing and connector performance, very high strength and elasticity, excellent stress-relaxation resistance and a non-galling bearing surface. LBA’s Hardiall®, Niclafor® 1000 and Declafor® lines are a qualified, lead- and beryllium-free upgrade path from C17200 copper-beryllium.
Key characteristics.
Very high strength & elasticity
Spinodal hardening rivals copper-beryllium mechanics.
Stress-relaxation resistance
Holds contact force through thermal cycling.
Non-galling bearing surface
Excellent friction, shock and wear behaviour.
Be- & lead-free
Recyclable upgrade from C17200, REACH / RoHS.
