Shihang CuZn20Al2 tube, also known as Arsenical Aluminum Brass or C67800 tube, is one of the topnotch metal products that have physical and mechanical properties that would surely suit industrial applications and satisfy your project’s demands, all while conforming to the ASTM B111 standards.
As alloys of this type are usually used in extremely corrosive environments, such as highly polluted and salinized wet solutions, particularly seawater, our Shihang CuZn20Al2 tubes pose superior corrosion resistance. Dezincification, a special type of corrosion resulting from high water temperatures, presence of chlorides, and other deviating qualities of water, is particularly prevented due to the stable chemical composition of our Shihang CuZn20Al2 tubes. The arsenic content incorporated in our tube production prevents the gradual weakening of our Shihang CuZn20Al2 tubes, averting eventual failures and leaks. This distinct characteristic of our Shihang CuZn20Al2 tubes makes it best used as heat exchangers and condenser tubes, ferrules, and other components for seawater condensers situated off-shore.
Moreover, our Shihang CuZn20Al2 tubes are also manufactured at controlled amounts of aluminum that allows the material to develop a protective film that has self-healing properties. This makes our Shihang CuZn20Al2 tubes suitable for seawater trunking and oil tanker heating coils. This also contributes to our Shihang CuZn20Al2 tubes’ high resistance to erosion and impingement attacks, which support its high applicability and usability in marine use, in either stagnant or relatively fast-moving salt and brackish water.
Aside from these, our Shihang CuZn20Al2 tubes have the distinguishable bright gold-like color of brass and have smooth finish, remarkable strength and hardness, making it as aesthetically good and sturdy as possible. Our Shihang CuZn20Al2 tubes also have higher malleability among other copper alloys and notably good electrical and thermal conductivity that would perfectly deliver to your heating and electrical necessities.
Shihang CuZn20Al2 tubes also have excellent machinability, making it easy to be fabricated and formed according to your specified use. Application-wise, our Shihang CuZn20Al2 tubes are best assembled through soldering, brazing, and welding, specifically, via oxyacetylene welding, gas-shielded arc welding, spot welding, seam welding, and butt welding.
Here in Shihang, our CuZn20Al2 tubes are produced in 500T per month, and will surely comply and provide to your fast-tracked requirements. This high productivity is also accompanied with high-quality control and assurance when it comes to the chemical composition, precise dimensions, and other design considerations in the Shihang CuZn20Al2 tubes that we produce. Upon drawing, annealing, and/or heat-treat tempering processes, our Shihang CuZn20Al2 tubes are tested to ensure that its quality meets the ASTM B111 standards.
To ensure the usability of our Shihang CuZn20Al2 tubes, we also offer subsequent stress reliving thermal treatment and product testing that will go well with your preferred product specifications. These include:
- A residual stress test that may be specified in the purchase order for CuZn20Al2 tubes that are not annealed temper;
- Optional post-straightening thermal treatment of the CuZn20Al2 tubes to be used in aggressive environments that pose potential stress-corrosion cracking failures.
From our plant to your site, your orders will come in our wooden case packaging. We assure safe materials handling and immediate delivery of our products to reach you in its best condition.
