Aluminium Brass Pipes – Supplier, Stockist
and Exporter in Mumbai, India

Aluminium Brass (UNS C68700) Pipes to ASTM B111

Aluminium brass (UNS C68700) contains about 77.5% copper, 20.5% zinc and 2% aluminium, with 0.02–0.06% arsenic to inhibit dezincification. The aluminium forms a tough, self-healing oxide film on the surface.

Properties and Uses of Aluminium Brass Pipes

That protective film gives aluminium brass better resistance than Admiralty brass to seawater, higher flow velocities and erosion-corrosion, which makes it a standard choice for seawater-cooled condensers.

Where not to use it: Aluminium brass is not suitable for ammonia-bearing service or sulphide-polluted seawater. For the most demanding seawater duty choose 90/10 cupro-nickel or 70/30 cupro-nickel.

Testing, Documentation and Packaging

Every lot of Aluminium Brass pipes is inspected before dispatch. Typical tests include chemical analysis / PMI, tensile and hardness testing, flaring and flattening tests, hydrostatic or eddy-current testing, and dimensional inspection. Third-party inspection can be arranged on request.

Material is supplied with a mill test certificate to EN 10204 3.1, together with the raw-material report and inspection reports. For export orders it is wrapped in poly bags and packed in fumigated wooden cases, crates or pallets, with a fumigation certificate included.
