Copper has always been the standard material for electrical wiring systems. Because it can flow electricity very easily as it is a good conductor. We offer a comprehensive range of copper wire to our clients in various specifications of diameter and length.These hi-quality wire have excellent electrical and thermal properties and supplied with spools, coils or straightened. They are Useful in motor winding wire, cables, transformer winding, telecommunications, explosives, fuse wires, railways and many applications. They are produced, hard or annealed by copper wire rods which are drawn down to thickness 1,40 mm - 8mm. They are according with TS 3, DIN EN 13601, DIN EN 13602. General properties material with minimum copper content 99.95%.

Constantan® is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges. The TCR can be adjusted from the furnished cold rolled values by using a low temperature heat treatment to achieve compensation for all types of spring elements. The foil is normally supplied with 90% cold reduction and a smooth bright surface. The foil is reasonably flat at 4” wide and nearly free of pinholes. The cold rolled foil can be produced with a TCR between +10 to –35 PPM/°C. The heat treatment will shift the foil TCR to the desired value. A typical heat-treat curve for Constantan® shows decreasing resistivity but increasing TCR with increased heat-treating temperature.

Shunt Manganin is a Copper-Manganese resistance alloy used for shunts in various high current applications. The alloy has a low temperature coefficient of resistivity with peak resistance at about 50°C. The thermal EMF vs. Copper is very low. The alloy can be easily formed from the annealed temper.The maximum recommended operating temperature in air is 200°F. Available Sizes: Shunt Manganin is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005 to 0.053” (0.0127 mm to 1.346 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000100” (0.00254 mm) in widths of 4.0” (101.6 mm) maximum.

ECU 99,9 % : Electrolytic is used as copper material with a conductivity of 58, electrode in erosion, high-low current panel and busbar in substations. Among our standard products: Rod, Sheet Plate, Straight pipe, Tube Coil, Box profile, Grounding rod - plate, Roofing, Copper fittings and thin wires. Also, sheet plate measurements which do not have a standard are brought to necessary measurement by forging at desired dimensions. Parts that require CU-Cr-Zr (Chromium alloy) High electricity conductivity, hardness and strength at high temperatures: Are used as point welding electrode and seam welding disc at the source of low carbon steels (Panel radiator, Gasoline warehouse, etc.) and Galvanized steel plate (Automotive and white goods), electrode holder at spot welding machines, plunger electrode at erosion machines and contact busbar at substations.

Busbars are typically used in high current, low voltage distribution and control equipment. Typical busbar applications include busway systems, low and medium voltage switchgear, transformers, earthing, electrification - lines panel boards, switchboards, and feeds to heavy electrical uses in commercial and industrial buildings - such as plating cells and feeder systems. Busbars can be made from copper or aluminum, but we couldn’ t argue the reality that copper bus bars are the better electrical conductors. Also installers can use smaller busbars if they are made by copper. On the other hand copper busbars have better resistance to corrosion than the aluminum busbars.We have large production facilities for extruded and drawn flats in various production range of sizes and shapes for electrical engineering, anodes, components etc.
