CHEMICAL BRASS PASSIVATION
This treatment protect copper and copper alloy. The passivation can be considered an excellent finishing treatment, in view of its high corrosion resistance
(more 360 hours of salt spray test)
CHEMICAL ALLUMINIUM PASSIVATION uni 9921
This treatment protect alluminium. The passivation can be considered an excellent finishing treatment,in view of its high corrosion resistance, even it has been studied as intermediate coating anchorage for the subsequent painting. This treatment allows to obtain a inert film throught the transformation of the superficial coating of Aluminium into amorphous compounds.
GALVANIC ZINC PLATING uni 2081/09
This treatment is used mainly to cover ferrous material. The purpose, over whether to furnish a resistance to the corrosion (rust) is also to confer an aspect of color and brightness different from the metal on which is deposed.
The colors of the passivantis in Cr III are: white-blue, yellow, white iridescent and black.
GALVANIC TIN PLATING AND GALVANINC COPPER PLATING uni 2093 iec 60068-2-20
Coatings of copper and tin.
Tin plating: The treatment is mainly used to protect the substrate against corrosion and to improve soldering. It guarantees,furthermore,an excellent electric conductivity,being for this reason that it’s also used for electric components.
Copper plating: This is a treatment used either to improve electric contacts as to prepare subsequent treatments.
GALVANIC NICKEL PLATING uni 1456
Nickel coating to protect metals. electrochemical
This is a treatment of excellent protection for fine objects and also for those of small dimensions, because the Nickel deposits are very homogeneous and higly compact. This coating carries out a metallic film of good hardness and abrasion resistance.
GALVANIC SILVER PLATING uni 4521
Silver coating to protect metals.
This treatment is used for decoration purposes and/or in electrotechnology,to improve the electric conductivity. The soldering of silver plated articles is excellent in all conditions.
GALVANIC GOLD PLATING uni 4523
Gold coating to protect metals.
The treatment of galvanic gold plating is used either as decorative coating as to protect surfaces which have to keep their soldering properties for long time. Furthemore the coating guarantees an excellent electric conductivity, reason for which it is used for making electronic components.
CHEMICAL NICKEL PLATING
Coating of chemical nickel.
The purpose is to deposit in way uniform for by chemistry the nickel sensitively increasing her/it of it hardness to around 500 Vickers and penetrating inside the particular ones with the same surface external.
STATIC ANTICORROSIVE ELECTROLYTIC SURFACE TREATMENTS : GALVANIZING
With this treatment we get blue-white finish , the trivalent iridescent , commercially known as ” LANTHANE ” and yellow . A service that is applied is the dehydrogenation .
The metal components that we are able to treat obtained zinc deposits significant even in the presence of closed cavities
and deep. This is possible thanks to the use of equipment of new conception, handled in all phases of working and from a specific formulation of the galvanizing bath . The piece’s size that we treat in this production line are medium or small , considering that our customers are employed in the electronics , automotive , hydraulics and pneumatics sectors.
We also equipped the line of a thickness gauge of the type ” induction ” , the precision of less than 0.1 microns compared to our X-ray apparatus , so as to constantly monitor , if necessary, the progress of the processing . The plant is completely closed cycle for what concerns water discharges . Our treatments trought the use of barrels with holes from 0,6 to 3 mm in diameter.
