Copper alloys are very suitable for recycling

About 40% of the annual consumption of alloys of this metal is supplied from recycled Copper materials.

Tensile strength
The tensile point of copper metal alloys is not clearly defined. It is more common than at 0.5% tensile strength, the yield strength of annealed materials is considered as one-third of their tensile strength. Cold working hardening means that the materials become harder and their ductility decreases and the yield strength approaches the tensile strength.

Cold and hot work
Both copper and its alloys can be cooled and heated. Ductility can be recovered by annealing or accidental annealing during welding or soldering.

Electrical conductivity
The electrical conductivity of this product is in the second place after Silver and it is 97%. Due to its lower cost and higher frequency, it is traditionally used as a standard material for electricity transmission applications. Although from a weighted point of view, a large proportion of high voltage power lines now use more Aluminum than copper, the conductivity of aluminum is about twice that of copper.

These aluminum alloys have low strength and need to be improved by galvanizing or coating aluminum with high tensile strength Steel wires in each layer. Although the addition of other elements improves properties such as strength, it does cause some reduction in electrical conductivity. For example, adding 1% cadmium can increase strength by 50%, but electrical conductivity can be reduced by 15%.

Thermal conductivity
The thermal conductivity of this metal is about twice that of aluminum and 30 times that of stainless steel. Copper is therefore used for applications that require rapid heat transfer, such as kitchen utensils, heat exchangers, car and vehicle radiators, and computer heat storage units, rotating disks, and television sets.

Corrosion resistance:
All alloys of this metal have corrosion resistance against water and steam. In most industrial and marine atmospheres, the alloys of this product have corrosion resistance. The metal is resistant to saline solutions, soils, non-oxide minerals, organic acids, and caustic solutions. 

Wet Ammonia solution, halogens, sulfides, solutions containing ammonia ions, and oxide acids, such as nitric acid, will attack copper. The corrosion resistance of copper alloys is due to the formation of adhesive films on the surface of the material. These films are relatively impermeable to corrosion, thus protecting the base metal from further attack. Cu-Ni alloys, aluminum brass, and aluminum show excellent corrosion resistance in saltwater.
