9. Copper, Copper, Cuprum (Cu)
Copper is one of the important metal as the material use is very widespread technique used both in the pure state or in the form of alloys. Pull the copper with the power of 150 N/mm2 as Copper Cast and the cold working process Copper tensile strength can be increased up to 390 N/mm2 as well as hardness numbers where Copper Cor has a hardness number increased to 45 HB and HB 90 through cold working process, with thus also be obtained Copper tenacious nature and can be maintained in spite of the heat treatment process is carried out for example with Tempering (See Heat treatment).
Properties as a conductor of electricity and heat better than copper (Electrical and Thermal Conductor) Copper and second only to the Copper Silver yet required to have a purity of up to 99.9%. One of the good properties of copper are also resistance to atmospheric corrosion even other types of corrosion.
Copper is easily formed and connected via soldering (Soldering), Brazing and welding (Welding). To discuss more about Copper can be seen in the description of Copper and its alloys.
10. Magnesium (Mg)
Magnesium is a silvery white metal and very shiny with a melting point of 6510C which can be used as a lightweight alloy material, together with the nature and characteristics of Aluminum. The difference is very small but its melting point is slightly different with Aluminum easy, especially on porous surfaces in case of oxidation with air.
Oxide film that coats the surface of Magnesium just enough to protect it from the influence of dry air, moist air while the salt content of the element of Magnesium oxid strength will decrease, by you indulge it with paint protection or lac (varnish) is a method to protect the corrosion effect Magnesiumdari humidity.
Magnesium has a tensile strength up to 110 N/mm2 and can be improved through the process of establishing up to 200 N/mm2. Magnesium have the gentle nature despite the low elasticity. To find out various things about Magnesium can be seen in the discussion of Magnesium and its alloys.
