Our company is specialized in the processing of copper alloys, in particular bronze and brass.
The alloys used for our standard production are:
Products in CW602N are also available.
Other alloys can be worked on customer request.


Almost all our production follows the UNI EN 10226-1:2006 regulation with taper external threads and cylindrical inner threads. Because of some obvious technical reasons, some items follow the UNI ISO 228/1 Parte 1° regulation of 01/1983 with cylindrical external and inner threads.
Other types of threads can be supplied on request.

Design Characteristics

All our products are designed and realized through modern CAD-CAM systems.
Our company is particularly careful to the life of every single article and therefore oversizing, hardiness and greater thickness in the more stressed parts are typical features of Maestrini production.

Before being mass produced, every new article is subject to tests which are decidely stricter than those it will have to face during its working life.

Technical-Constructive Characteristics

Our company does not make use of external turneries (contractors), but follows directly the whole production.
In this way, it is possible to keep under control every single piece and reach an excellent quality.

The wide range of products cannot be constructed on only one kind of machine, consequently the company uses automatic CNC lathes for the production of items of small dimensions, CNC transfert machines for items of medium dimensions and CNC centers for items of big dimensions.
There are also automatic multi spindle machines for the mass production and normal CNC lathes for shorter series.
Our articles can be obtained from bar, pressed or casted semifinished goods, but never from diecasting.
