Admiralty Brass Tubes are generally used with fresh, clean waters free from suspended abrasive solids and originating from rivers lakes and canals. It may also be used with brackish or even saline water. The inhibitive action of arsenic protects Admiralty Brass Tubes from dezincification and the fully annealed alloy can also withstand stress-corrosion cracking. In waters containing less than 2000 ppm dissolved solids its use is allowed at flow rates of up to 3 m/s (10 ft/s) in sea waters a maximum speed of 1 m/s (3,0 ft/ s) is recommended. The presences of tin improve resistance to general corrosion in slightly polluted (sulphurised) water.

Brass
Extensive warehouse stocks of a wide variety of brass alloys ensure we stay flexible. We don‘t simply stock the standards such as Cu Zn37 or Cu Zn39 Pb.
Our portfolio also extends to special alloys such as Cu Zn37 Mn3 Al2 Pb Si, Cu Zn35 Ni3 Mn2 Al Pb and many more – stocked as bars, sheets, plates, tubes and sections.

All that glitters is not gold Hollow Brass Tube Rod
At DOWEDO, this old proverb applies very well to brass. We maintain vast stocks of this material. Whether for the fittings or engineering sectors – whether for release orders or a small section for fabricating a hexagon bolt. Here, diversity is the key.
Whether you need round bars from 1.5 mm in diameter, brass tubes (round or rectangular) or heavy brass plate up to 200 mm thick …
