Product Description
NACOBRE DENOMINATION: 687

DESIGNATION: ALUMINUM BRASS, ARSENICAL.


Aluminum Brass, Arsenical 687 is the trade name assigned to aluminum brass condenser tubes developed and produced by Nacobre. Aluminum Brass, Arsenical 687 Condenser Tubes are specially adapted to resist corrosion by both salt and brackish waters under many operating conditions in power plants, marine service, and oil refineries. These tubes will handle most sewage-contaminated salt waters without serious corrosion.

The alloy quickly forms and maintains a protective surface film which is resistant to the impinging action of turbulently flowing sea water containing air bubbles. It is also resistant to sea water containing abrasive solids. Aluminum Brass, Arsenical 687 is highly resistant to dezincification corrosion because of its arsenic content. It has largely replaced Admiralty in condensers and in some auxiliary equipment, because it has better resistance to seawater corrosion under severe conditions.
