We provide turning and milling of copper, brass and bronze components. Brass and copper machining covers parts for power generation, electrical engineering, hydraulics and the marine industry.
We specialise in CNC machining of copper and bronze alloys: 3-, 4- and 5-axis turning and milling, drilling, threading, grooving and deburring of sealing surfaces. We coordinate polishing with partners. We machine precision parts for power generation, electrical engineering, hydraulics and the marine industry.
We work with copper and bronze alloys sold under the following trade names: Ampcoloy® (Ampco Metal – aluminium bronzes, copper alloys for tooling), DURONIC® (Lebronze Alloys – high-strength tin bronzes), Ampco® 21, 22, 25 alloys (aluminium bronzes for marine and aerospace industries) and ToughMet® (Materion – spinodal bronze with exceptional wear resistance).
We machine 12 main grades of copper, brass, bronze and copper-nickel alloys in EN / DIN / UNS / Polish designations. Coppers and brasses (6): Cu-ETP (M1E) grade, Cu-OF grade, Cu-DHP grade, CuZn37 (Ms63 brass) grade, CuZn37Mn3Al2PbSi grade and CuZn39Sn1 grade (naval brass). Bronzes and copper-nickel alloys (6): CuSn12 (B101) grade, CuSn7Zn4Pb7 grade, CuAl10Fe5Ni5-C grade, CuAl10Ni5Fe4 grade, CuZn25Al5Mn4Fe3 grade, CuNi10Fe1Mn grade.
Key properties of copper and bronze alloys:
We mill and turn busbars, switchgear parts, conductive plates, joints and earthing systems from M1E (Cu-ETP) copper. Electrical conductivity >100% IACS and excellent thermal conductivity are key for power components and heat exchangers. Cu-OF is selected for electronics, vacuum and cryogenics.
We turn bearings, bushes, sliding guides and worm gears from CuSn12 (B101) tin bronze. Its very high wear resistance and low coefficient of friction, resulting from the high tin content (12%), suit heavily loaded friction pairs.
We machine hydraulic fittings, joints, valve bodies and flanges from CuSn7Zn4Pb7 leaded bronze because of its very good machinability. We use CuZn39Sn1 naval brass for marine shafts, hydraulic joints and propellers.
We use CuAl10Ni5Fe4 aluminium bronze for aerospace components, offshore bushes and pump parts. We use CuNi10Fe1Mn copper-nickel alloy in marine pipework, condensers and marine systems. CuZn25Al5Mn4Fe3 manganese bronze is used for worm gears and marine propellers.

Copper and bronze alloys are widely used in power generation, electrical engineering, hydraulics, marine and chemical industries, and precision engineering. They are valued for excellent thermal and electrical conductivity, corrosion resistance, wear resistance and very good machinability. We make copper and bronze components by precision CNC turning and milling.
Cu-ETP (M1E, UNS C11000) grade – electrolytic copper, conductivity >100% IACS, busbars and electrical components. Cu-OF (UNS C10100) grade – oxygen-free copper, electronics, vacuum, cryogenics. Cu-DHP (UNS C12200) grade – phosphorus-deoxidised copper, installations, HVAC, heat exchangers. CuZn37 (EN CW508L, Ms63 brass, UNS C27200) grade – good machinability, fittings, connectors. CuZn39Sn1 (EN CW719R, naval brass, UNS C46400) grade – hydraulics and the marine industry.

I can wholeheartedly recommend Anbi-Tech as a reliable and professional partner in machining and in manufacturing parts for the pharmaceutical industry. This is the third company where I have had the pleasure of working with Anbi-Tech, and the cooperation has been of the highest standard every time.
The pharmaceutical industry is exceptionally demanding: precision, on-time delivery, material quality and a full understanding of the customer’s needs all matter. Anbi-Tech has repeatedly proved that it is very well suited to this environment. The company has manufactured change parts, spare parts, filling needles, conveyor screws, components for dispensing powders and liquids, and many other production components for us.
The quality of the parts deserves particular recognition, whether they are made from 316L and 304 stainless steel or plastics such as POM, polyurethane and polycarbonate. The components are manufactured to a very high standard, with close attention to accuracy and detail, which is crucial in our industry.
Anbi-Tech has literally ‘saved our skin’ on many occasions in emergencies where time, a rapid response and a flexible approach to the customer mattered. A major strength of the company is its modern machinery, which enables it to complete even highly demanding projects while maintaining the highest standard of workmanship.
The people are equally important: the company’s staff always show complete commitment and a willingness to cooperate and provide technical support. Their extensive experience, professionalism and collaborative approach to customers are clear to see.
In pharmaceuticals, the ‘paperwork’, meaning certificates, is also important. The certificates have never been questioned during customer or regulatory audits, for example by GIF.
I strongly recommend working with Anbi-Tech to any company looking for a proven, reliable and quality-focused technical partner.
Dariusz Stachowicz, Senior Maintenance Manager, Polfa Warszawa S.A.
We had a very good experience working with Anbi-Tech on a new production line project for a bottling plant. Using a bottle sample and components from the old line, its engineer prepared the design and documentation for new change parts in SolidWorks. Anbi-Tech then manufactured timing screws, star wheels, drive components, bottle orienters, bottle turners and feeding components, among other items.
A major advantage is the end-to-end approach, from analysis and design through to the manufacture of finished components. Their considerable technical experience, precision and ability to solve unusual problems are clear. I recommend them.
Bartłomiej Ć, Specialist, ORLEN
We work with Anbi-Tech to manufacture parts and technical components for our projects. We value them above all for their workmanship, on-time delivery and excellent communication. When requirements are unusual, they can advise us and find a solution instead of simply manufacturing a part from a drawing. A reliable partner that I am happy to recommend.
Marek P., Production Manager, Triccor
A reliable company with extensive experience! They manufacture parts from steel, aluminium and specialist plastics such as POM and PTFE. Every service, whether turning, milling or CNC cutting, is carried out perfectly and with attention to the smallest detail. Excellent communication, professional advice and consistently on-time delivery. I wholeheartedly recommend them to anyone who needs reliable components.

For a quotation, send a PDF or DXF drawing or a STEP model with dimensions. State the material, the number of pieces and the quality requirements. A photograph of the part alone, without dimensions, does not allow a reliable quotation to be prepared.
If the project combines several operations, we will agree the scope of machining, inspection, assembly and processes carried out by partners.
