| Offering plated and plain finishes according to customers' requirements, the ISO 9002 certified company Bolton Wire Ltd (formerly United Wire Ltd), UK, specialises in the production of high-quality brass, phosphor bronze and nickel silver wires, made from premium grade raw materials to ensure the highest standards and designed for a myriad of particular uses. The British company specialises in technically challenging applications, such as brass wire used in alkaline batteries. The alkaline cells are built around a central anode charge collector shaped in the form of a nail or rivet. Bolton Wire offers both CuZn30 and CuZn37 for this application.
Some customers take the material with a plain finish, however most of them find that tin-plated wire offers the best value for money, because the need for expensive barrel plating applied after nail making is avoided. Four little studs, two at each end, connect fluorescent tubes to their fittings. Cold extrusion processes are used to produce the complex hollow shape from solid wire. CuZn30 was selected because of its extreme malleability, good corrosion resistance, high-electrical conductivity and high-mechanical strength. CuSn5, CuZn30 and CuNi12Zn24 wires are all used in fusion fittings when laying polymer pipes for water and gas networks. The fittings are used to weld one length of pipe to another. Copper alloy wire, inlaid in the surface of the fittings, acts as an electrical resistance element for the welding process. The joints are guaranteed for fifty years.
Other applications include wire brushes, springs, PCB's, electronic connectors, vacuum cleaners, clutch plates, cable pullers, zips, toothbrushes, model railway lines, picture frame hangers, wire cloth, haberdashery and scouring pads to name but a few. Bolton Wire Ltd exports about 80 per cent of its production to customers in China, North and South America, Australia, Africa as well as Europe, and, placing great emphasis on the co-operative development of technology to satisfy customers present and foreseeable needs, the British company also ensures on-time delivery of quality assured product and after sales service.
