Wear-resistant coating service DELSUN®

coppernickelaluminum alloy

Surface treatment for the prevention of wear and seizure of copper alloy parts. This treatment is obtained by tin base electrolytic plating followed by diffusion heat treatment at 400°C (752°F). Characteristics: • Increased surface hardness • Improved adherence of lubricating films • Reduced friction coefficient on lubricated parts • Excellent abrasion resistance Materials suitable for treatment: Bronze • Brass • Copper-aluminium alloys • Copper-nickel alloys. Small / Medium / Large series Copper alloy ISO Standard Examples of use: • Tap and fitting nuts and screws • Shell bearings • Worm screw gear reducer wheels • Spherical gates • Support plates • Pump bodies • Gearboxes synchronisers • Guide bushes • Idle gears forks • Valves • Hinging rings • Machine tool wedges • Linkages, couplings • Valve guides
