Brass is an alloy composed of Copper and Zinc. Different varieties of this metal can be created depending on the proportion of its composition as well as different properties are obtained. Other materials can also be added. It is of a color similar to gold. Depending on the composition, both the density and the fusion vary. It has a density between 8.4 and 8.7gr / cm3 and its fusion is between 900 and 940 ° C. The composition of brass influences the mechanical characteristics, for For this reason, there must be less than 50% zinc in the industrial brass, the ingots obtained cold can be transformed into sheets with different thicknesses, rods or strips for the manufacture of wires. Brass is highly resistant to rust and corrosion even in high salinity conditions, which is why it is used to build ships. It does not produce sparks on mechanical impact. It is a strong metal against wear and tear and is also a good conductor of electricity. It has facility to deform plastically without breaking (ductility) and also has machinability both in cold and in heat. It can be exposed to extreme temperatures or light without disturbing the material. Depending on the percentage of zinc it contains, there are three main groups of brasses: First title: Zinc 34% Second title: Zinc between 33% -44% Third title: more than 42%. Not recommended for industrial use As for ordinary brasses, three can be distinguished: Red brasses (between 10% -20% zinc): One of these brasses is the one used in jewelry since it looks like gold. Yellow brasses (between 25% -35% Zinc): they are brasses for springs, cartridges, ammunition…. Alpha + beta brasses (between 36% -42% Zinc): it is less ductile than the previous two and they are not cold rolled, they are worked hot. Special brasses are those to which another type of material is also added, the most common are the following: Brass to aluminum Brass to iron: better toughness and tensile strength Lead brass: has mechanical strength and machinability Manganese brass: it has more tensile strength and is less ductile. Tin brass: It is more resistant to traction and corrosion. The best known alloys are admiralty metal and naval brass (zinc 40%) Silicon brass: for example, bronze is very resistant to corrosion Complex brass: highly resistant to corrosion and cavitation. Brass is produced when copper is fused with calamine, a mineral in zinc. In the melting process, the zinc is extracted from the calamine and mixed with the copper. The manufacture of primary brass has a high economic value as it is an alloy of copper and zinc. In addition, being able to recycle, it would be an unnecessary waste of raw materials. Brass manufacturers use scrap of this metal to make their products. The recycling of this material is simple since it does not need the electrorefining process like other materials. To obtain recycled brass with the same properties as the original, you only have to melt the brass scrap as long as it is clean of other residues.
