Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion.The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both these are imprecise terms, both having been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially by

Experiment on the use of sand, calcite and clay for Pb 2+, Zn 2+ and Cu 2+ sorption in the presence of humid acids had found that, at higher pH levels, heavy metals are removed from solution by coprecipitation with calcite or by sorption on Fe or Mn oxides that are precipitated on carbonate particles (Petrovic et al., 1999). The term sorption referred as all phenomena at the solid

Solder alloys are metallic materials that are used to connect metal workpieces. This is achieved by melting the alloy and then cooling it down. The choice of specific alloy depends on its melting point, chemical reactivity, mechanical properties, toxicity, and other properties.Hence a wide range of solder alloys exist, and only major ones are listed below.
