Product Code : ME-Cu-6N-BR
Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
ATT certified high purity Copper Bars for short and long term physical possession and to allow for exposure and controlled risk to industrial demand fluctuations reflected in the global copper price. Bars are manufactured and minted under written High Purity (99.99%) Metallic BarsSOPs (standard operating procedures) to assure quality and consistency by ATT' AE Metals™ custom synthesis and refining group. Besides copper bars, copper coins and copper Ingots may be purchased by funds, currency reserves, exchange-traded funds (ETFs), private investors, collectors and hobbyists to take direct physical title and possession of the metal with risk exposure from shortages or chemical/physical technology changes, such as in solar energy, and fuel cell developments, equivalent to movements in the industrial application price of Copper.

Applications of Copper Bar
It is typically used as a conductor of electricity and heat, as well as a building material. It is also used as a constituent of various metal alloys. Copper's freshly exposed surface has a reddish-orange color, but architectural structures built with copper corrode to give green verdigris or patina.
Packing of Copper Bar
Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
ATTs’Copper Bar is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
