B6 | Bronze Copper Alloy Tin Phosphorus
Available formats: Bars, Tubes, Caps, Plates and Plates.
B6 or CuSn6 provides an excellent combination of strength, cold formability and hardness. It is wear resistant, has good corrosion resistance and welding properties.
Due to its high strength and elasticity, combined with good machining properties, it is used for all types of springs and flexible metal pipes.
We offer exceptionally narrow tolerances with respect to chemical composition, dimensional accuracy and mechanical properties.
Special features, such as extra-fine particle size or relief of thermal mechanical stress, improve mechanical properties and
They provide greater strength and greater malleability.
Applications
Electric: Miniaturized connectors, Contact springs, Relay springs, Electric flex contact blades, Terminals, Switch parts, Fuse clips, Electronic connectors, Resistance cable, Electromechanical spring components, Electric flex contact sheets, Wire brushes, Switch parts, Electronic and precision instrument parts.
Closures: lock washers, cotter pins, fasteners.
Industrial: Bourdon tube, bellows, textile machinery, perforated sheets, springs, sleeve bushings, clutch discs, beater bars, chemical.
General: stamped parts, connectors, contact springs, spring elements, ultra-high force spring elements, membranes, switch elements, fixed contacts.
