Exothermic welding is one kind of exothermic welding methods which use super high heat produced by chemical reaction (exothermic reaction) to complete welding. Exothermic welding is also called as fireclay fusion joining, fireclay fusion welding, exothermic fusion welding, exothermic welding, chemical heat fusion welding, etc. Chemical reaction rate for exothermic welding is so fast that it only needs a few seconds to complete welding. Produced super high heat can effectively conduct to fusion part so that it is melted to form bonded molecular. No other heat is required. It is the best method to weld metal conductor for ground circuit. See IEEE STD.80-1976. Exothermic welding mainly weld pure copper, brass, bronze, copper, copper-clad steel, pure iron, stainless steel, ductile iron, zinc plated steel, cast iron, copper alloy, alloy steel and etc. Welding materials produced by our company are safe, nontoxic and friendly environmental since they dont use phosphor and dangerous chemicals easily producing metal toxic gasses used by other flux. Gasses produced by reaction are CO2 and H2O so that there are no occupational diseases risks for operators and emission gasses has no pollution to atmosphere. Our company adopts unique formula with delay reactant, pore removal agent, residue resistant agent, etc. to effectively assure welding quality and personnel operation safety. Sea standard.
1. Specific workmanship: BSD series Copper Bonded Ground Wires(Cables) are made of high-quality Steel core coved with 99.9£¥ electrolytic copper molecular. 2. Corrosive nature: The thickness of surface copper plated layer is 0.25mm. Molecular bond with steel core surface is formed by electroforming process, which is highly conglutinated and good anticorrosive, it is ensured that Ground wires can be used at least fifty years. 3. Conductivity: BSD Copper bonded ground wire has good conductivity, and the electric resistance is more lower comparing with common conduct material. 4. Widely used: BSD Copper bonded ground wire can be used in soil surroundings with various temperature,humidity,PH value and etc. 5. Operation: Accessories full equipped, matched with our advanced exothermic welding technology, make construction safety and easily installed. 6. Cost cut down: It is the best replacement of traditional material pure copper, and cut down cost drastically. Packing by drum

We hold immense expertise in making available Copper in many forms including LME registered and non registered cathodes, billets, rods, cakes, bars, foil, sheet, granules, plates, powder, shot, turnings, wire, insulated wire, mesh and “evaporation slugs”. Copper is one of the most important metals. Copper is reddish with a bright metallic lustre. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity). Its alloys, brass and bronze, are very important. Monel and gun metals also contain copper. The most important compounds are the oxide and the sulphate, (blue vitriol

Hindalco's copper division, Birla Copper, operates one of the largest single-location custom copper smelters in the world. The custom copper smelter at Dahej in the state of Gujarat (west coast of India) houses three copper smelters, three refineries, two rod plants, a captive power plant, a captive oxygen plant, phosphoric acid plant, di-ammonium phosphate plant, precious metal recovery plant, captive jetty and other utilities. Hindalco produces LME grade copper cathodes, continuous cast copper rods in various sizes, and precious metals like gold and silver. Hindalco is one of the major manufacturers of 19.6mm diameter copper rods, which is used for railway electrification. The co-product, sulphuric acid, is partly utilised to produce phosphoric acid and fertilisers like di-ammonium phosphate (DAP). Birla Copper's brands, Birla Copper and Birla Copper II, are recognized for their high purity and consistent quality in the domestic as well as global markets. Birla Copper is an ISO 9001, 14001, 27001, 50001 and OHSAS 18001 certified company, registered on the London Metal Exchange as Grade-A copper brand, and certified as a Star Trading House having labs for chemical, mechanical and electrical testing accredited by the National Accreditation Board for Laboratories (NABL).
