Tin mechanical platingDELSUN™

aluminum nickel

DELSUN™ 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 300°C (572° F). Characteristics : Improves surface hardness. Improves adherence of lubricating films. Decreases the friction coefficient when parts are lubricated. Excellent resistance to abrasion. Materials suitable for treatment : Bronze, brass, copper-aluminium alloys, copper-nickel alloys. Application examples : TAP AND FITTING NUTS AND SCREWS, SHELL BEARINGS, WORM SCREW GEAR REDUCER WHEELS, SPHERICAL GATES, SUPPORT PLATES, PUMP BODIES, GEARBOX SYNCHRONISERS, GUIDE BUSHES, IDLE GEAR FORKS, VALVES, HINGING RINGS, MACHINE TOOL WEDGES, BEARING BLOCKS, LINKAGES, COUPLINGS, VALVE GUIDES, STAMPING DIES, CONTINUOUS CASTING MOULDS, etc.
