Product Details

ASTM B111 / ASME SB111 C68700 Aluminum Brass Copper Alloy Tube

To produce the most efficient Heat Exchanger for each application, we combine the most appropriate thermal and mechanical design solutions with most durable materials and the highest standards of welding and construction techniques.

As one of the biggest projects pipeline products supplier in China, YUHONG GROUP can supply a wide range of C68700 tubes in different specifications like ASTM B111. This specification establishes the requirements for ferrule stock and a seamless tube of copper alloys of a specified range of diameters.

UNS C68700 has especially good corrosion resistance properties in sea water. C44300 and C68700 tube have good corrosion resistance. C68700 annealed in O61 Temper. Tensile strength minimum in 345Mpa, Yield Strength minimum in 125Mpa.
C68700 Tube density in 8.33g/cm3, 0.301lb/in.3
Typical Application of C68700 Aluminum Brass "Arsenical"
1. Industrial: Condenser Tube, Evaporator Tubes, Ferrules, Distiller Tubes, Heat Exchanger Tubes
2. C68700 aluminium brass tubes are widely used in “Seawater desalting plants”
