Even though these types of brass exhibit a very good machinability, the effects of their chemical composition on the resistance of the alloy to corrosion cracking have not yet been given sufficient attention. This paper aims to present an assessment of three new types of machinable copper alloys ...

Copper is an extremely good conductor of heat and electricity, and this property of copper is responsible for its wide use in making utensils and electric wires. Copper is also a necessary trace element required by the human body. Copper is commonly extracted from its ores Chalcopyrite, also kn...
A combination of techniques including controlled atmosphere electron microscopy coupled with in situ electron diffraction has been used to follow the manner by which the nature of a carbonaceous support can impact both the chemistry and morphological properties of small copper particles when treated in ...
Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass...

Copper is the third most used metal in the world, and because of its physical and chemical properties such as high conductivity, corrosion resistance and excellent ductility, it is widely used in electric power, electric vehicles, telecommunications, computers, mobile phones, construction, transportatio...
oxidation in atmospheric condition. Generally pure metals such as iron, copper, aluminum etc. gets corroded in slowly in atmosphere. To avoid the corrosion of these metal in pure form, we use these metals in the form of alloys such as stainless steel, brass, bronze, German silver, Gunmetal ...
