Brass is an alloy consisting mainly of Copper (Cu) and Zinc (Zn) which is characterized by high qualities of ductility and malleability, as well as good resistance to corrosion. The machinability of the machine tools is good, but the toughness of the material tends to constitute very long chips: for this reason many times small percentages of lead are added which disperses on the grain edge and causes the reduction of the size of the chip produced, reducing, between the many problems, the overheating of the tools used.
Brass, which has different structures depending on the percentage of zinc, can be used in many applications: in particular, it is used for the realization of various types of fittings and also for the multilayer pipe fittings.
Nickel plating is a surface treatment that improves the corrosion resistance and durability of the component over time, even in difficult and particularly aggressive environments. Electrolytic nickel plating: can only be carried out on metals and occurs by immersing the component in baths where an electric current passage is created which leads to the surface deposition of a layer of nickel.
The realization of the multilayer pipe fittings in nickel-plated brass brings advantages both from the aesthetic point of view (it has a greater resistance to darkening with the passage of time) and as regards the hardness and resistance to corrosion by very aggressive environments, which can be , for example, the construction sites where the multilayer pipes with their respective fittings are put into operation.
