Copper & Copper Alloys
Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange colour. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.
We EXPORT, SUPPLY & STOCK the following Grades of Copper & Copper Alloys in form of pipes, tubes, sheets, bars, rods, wire & fabricated product like heat exchanger, pressure vessel, column & towers, etc.
