melting point; for annealing 800 degrees are needed. Iron‚ by comparison‚ has a melting point of 1538 degrees Celsius. Its low melting point makes copper easy to smelt‚ cast‚ and remelt without special furnaces or a heavy investment of fuel. Another advantage of copper is that it can be recycled without any loss of quality. As pure copper is too soft for structural elements or most practical appliances‚ it needs to be hardened and strengthened. It is therefore combined with

Modulus of elasticity: The ratio of the stress applied to a body to the strain those results in the body in response to it. The modulus of elasticity of a material is a measure of its stiffness and for most materials remains constant over a range of stress. . Material | Elastic Modulus | | MPa | psi | Steel | 200‚000 | 30‚000‚000 | Poisson ratio It is the negative ratio of transverse to axial strain. In fact‚ when a sample object is stretched (or squeezed)‚ to an extension (or contraction)
