C68700 Aluminum Brass Tube PDF
Products Description
B111 C68700 has especially good corrosion resistance properties in seawater. Its tensile strength minimum is 345Mpa and the yield strength minimum is 125Mpa. Its density is 8.33g/cm3, 0.301lb/in.3.
C68700 Aluminum Brass is applicable for condenser tube, evaporator tubes, distiller tubes, ferrules, and heat exchanger tubes. C68700 aluminum brass tubes are widely used in "Seawater desalting plants". A brass tube, a type of non-ferrous metal tube, is a pressed and drawn seamless tube. The brass tube is light in weight, good in thermal conductivity, and high in low-temperature strength.
Product Features
Exceptional Corrosion Resistance: Arsenic (As) inhibits dezincification (salt spray >720 hours with coating).
High Strength-Ductility Balance: Annealed tensile strength ≥360 MPa, elongation ≥50%; hardened strength up to 600 MPa.
Optimized Cold Workability: Cold deformation rate ≤80%, suitable for deep drawing/flaring.
Thermal Conductivity: 109 W/(m·K), electrical conductivity 28% IACS, ideal for heat exchange systems.
Environmental Safety: As ≤0.10%, compliant with REACH industrial exemptions for cooling water systems.

Heat Exchanger And Condensers Copper Alloy Tubes
| Admiralty C44300 | Highly resistant to general corrosion – where pressures, velocities and temperatures are moderate. |
| Alluminium Brass C68700 | These tubes are especially adapted to resist corrosion by both salt and brackish waters. |
| Copper Nickel 90/10 C70600 | This alloy is highly resistant to corrosion by turbulently flowing sea water indicate it to be an excellent condenser tube alloy for salt water use. |
| Copper Nickel 80/20 C71000 | This alloy has intermediate properties between those of 10% and 30% copper nickel. Tubes of this alloy have found widest use in feedwater heaters and evaporators. |
| Copper Nickel 70/30 C71500 | Condenser tubes of this alloy are giving long and dependable service at sea. It is also highly satisfactory for tubes in evaporators, condensers, and superheaters. This alloy is particularly desirable where high temperatures are encountered. |
Applications
C68700 aluminum brass tubes are commonly used in:
Condenser tubes for high-velocity cooling water
Seawater cooling systems in marine and offshore applications
Power station condensers (marine and land-based)
Desalination plants and saltwater treatment facilities
Heat exchangers exposed to turbulent or contaminated water
Industrial cooling systems with brackish or saline water circulation
