Locking Wire
Soft annealed wire that is used extensively in the aerospace, marine and automotive industries.
Stainless steels and nickel alloys are the principal materials used for safety locking wires in the Aerospace, marine and automotive industries. Supplied to UK, USA and European specs.
Aircraft control cableHigh specification aircraft control cable is stranded from aerospace quality hard stainless steel and galvanised high carbon spring steel fine wire.
Precision stainless steels in grades 304, 316, 316L and implant grade 316LVM are supplied in clean and highly polished condition for medical device manufacturers.
Orthodontic wireHighly polished stainless steels in 302 and 316 grades are manufactured for orthodontic laboratories and hospitals in round, indented flat and flattened strand.
High performance nickel alloys are produced to order and to specification for use in the manufacture of springs and clips for extreme conditions.
Stainless steelsA range of specialised stainless steels 316L and 321 which have increased corrosion resistance are used in both annealed and spring hard condition for component manufacture.
Spring hard stainless steels in 302 and 316 are manufactured, in round, flat or shapes for the manufacture of precision springs and clips.
Copper alloysA wide range of copper alloys including specialist alloys such as beryllium copper are manufactured to specifications, particularly for springs and contacts.
Nickel Chromium alloys provide the basis for the majority of electrical resistance wires used in heating applications up to 1150ºC.
HecnumHecnum is a trademark of Omega Wire, a subsidiary of KPW. Hecnum is a Copper Nickel alloy used extensively for the manufacture of resistors.
The principal stainless steel due to its high strength and good formability. KPW stocks and manufactures the range of materials 302, 304, 316 and 321, in a variety of tempers.
17/7 PHThis precipitation hardening stainless steel is typically heat treated after forming to produce a material of exceptionally high strength.
This is high carbon steel, characterised by its ability to harden significantly during cold working to produce wire forms of very high tensile strength.
Mild steelA low carbon version. This material is both cheap and easily formed, but with low strength, so is used for undemanding applications.
KPW manufactures a range of nickel alloys which exhibit very high strength and corrosion resistance at elevated temperatures.
Nickel alloy resistance wireNichrome and copper nickel are both manufactured for electrical resistance and general electrical applications.
A range of phosphor bronze alloys are manufactured, mainly in hard and spring hard condition for use in springs and electrical contacts.
Beryllium copperA specialist alloy of copper, beryllium copper can be heat treated to achieve very high tensile strengths making it ideal for high performance electrical contacts and springs.
Stocked in a range of purities and alloys, titanium has exceptional strength and low weight, making it ideal for the aerospace industry.
AluminiumThe principal characteristic of aluminium is its very low density, and it is used in applications where low weight is the main criteria.
KPW has the most comprehensive range of cut to length machines in the UK. Particular specialisations are the straightening and cutting to length of very fine wire without compromise to surface finish, and the cutting to length of spring hard stainless steels.
Five rolling mills enable KPW to produce a range of flat wire - from thin and narrow up to heavy section flat wires. Wires can be produced to high tolerance square corners using edging rolls, and a speciality is the production of high tensile flat wire for springs.
Square, half round and other shapes are produced using rolls and turkshead units. Materials produced include mild steel, stainless steel, brass and phosphor bronze.
A range of tubular stranding machines enables KPW to produce strands in stainless steel, nickel alloys and copper alloys in a variety of sizes, strand constructions and tempers.
KPW has a diverse range of wire handling equipment enabling the supply of wire in the format required by the customer - coils, formers or spools - and to the exact weight or length.
KPW have developed a range of specialist wire cleaning processes - mechanical polishing, vibro polishing, vapour degreasing and in-line ultrasonic cleaning.
