These prices are more an indication than an actual exchange price. Unlike the prices on an exchange, pricing providers tend to give a weekly or bi-weekly price. For each commodity they quote a range (low and high price) which reflect the buying and selling about 9-fold due to China's transition from light to heavy industry and its focus on ...
Copper's higher tensile strength (200–250 N/mm 2 annealed) compared to aluminium (100 N/mm 2 for typical conductor alloys [16]) is another reason why copper is used extensively in the building industry. Copper's high strength resists stretching, neck-down, creep, nicks and breaks, and thereby also prevents failures and service interruptions. [17]

The CuOFP capsule used as overpack for spent nuclear fuel disposal in the KBS-3 concept (Swedish version). Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.
Example of a copper alloy object: a Neo-Sumerian foundation figure of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.
