mechanical properties of copper ore

mechanical properties of copper ore,Copper - WikipediaAt the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms.mechanical properties of copper ore,Copper - Specifications, Properties, Classifications and Classes .May 17, 2005 . It is also often a by-product of silver production. Sulphides, oxides and carbonates are the most important ores. Copper and copper alloys are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability.

Fundamentals: Types of Copper and Properties

Because of its low strength, heavy gauge material was required. As a result, the use of soft temper copper is not recommended for most building applications. With the development of cold rolled copper many years ago, the gauge of the material could be reduced without compromising its low maintenance and long life.
