Aluminumbronze alloys, wear and corrosion resistant solutions for demanding applications.
Aluminumbronze is a robust alloy, popular in applications that require high resistance to wear and corrosion, such as in shipbuilding, offshore industry, and heavy machine parts. Our most common variants are continuously and centrifugally cast CuAl10Fe5Ni5-C – CC333G (CuAl10Ni) and pressed/drawn CuAl10Ni5Fe4 (CW307G).
In addition, we offer options such as CuAl10Fe3Mn2, CuAl11Fe6Ni6-C (CC334G), CuAl11Fe6Ni6 (CW308G) and CuAl10Fe2, ideal for specialty applications in pumps, valves, gears, and bearing systems.

Production capabilities
Bronze
Foundry
Maatmetaal has been centrifugally casting bronze tubes itself since 1987. With modern electric induction melting furnaces and various centrifugal casting machines, we are able to produce tubes in the range of Ø 200 to Ø 1250 mm, with a maximum casting weight of 2.5 tons, quickly and well.
Bus and ring manufacturing
The raw cast tubes are pre-turned to any desired size on our conventional and cnc-controlled turning and carousel lathes. We also have a CNC-controlled integrated turning/sawing machine with a turning/sawing capacity of up to Ø 1200 mm. Thus, in a single set-up, rings are pre-turned internally and externally and cut off with unprecedented accuracy by means of a circular saw.
Sawing
In addition to this state-of-the-art way of sawing rings, Maatmetaal has several bandsaw machines for cutting tubes and cutting discs.
