What is B171 C71500 material?
ASTM B171 Standard Specification
ASTM B171 defines requirements for copper-alloy plate and sheet (including C71500) used in pressure vessels, condensers, and heat exchangers. Key aspects include:
Manufacturing Process: Materials are produced via hot rolling/forging, followed by cold working and annealing to meet dimensional and property requirements.
Tempers: Available as hot-rolled or hot-rolled/annealed.
ASME Compliance: Products for ASME Boiler and Pressure Vessel Code applications must be certified to hot-rolled standards.
Applications
Pressure Vessels & Heat Exchangers: Used in LNG transport vessels and nuclear power plants due to high-temperature stability (up to 260°C).
Marine Engineering: Pipes and tubes for seawater systems (e.g., condensers, desalination plants).
Industrial Fluid Transport: Chemical equipment and high-pressure pipelines.
Comparison with Other Standards
ASTM SB 111: Focuses on seamless tubing, while B171 covers plate/sheet for pressure vessels.
International Equivalents:
UNS C71500: Matches ASTM B171's composition.
EN CuNi30: European equivalent with similar Ni content.

Our factory
Our manufacturing facility operates a comprehensive and modern production line, equipped with advanced continuous casting, precision rolling, high-speed drawing, and multi-axis CNC machining centers, enabling us to process copper and copper alloys (such as C10100, C11000, C12200, C71500,C70600 etc.) into a full range of products including tubes, sheets, rods, wires, and foils. To ensure top-tier quality, we have implemented a rigorous in-process and final inspection system, utilizing state-of-the-art equipment such as spectrometers for material verification, digital tensile testers for mechanical property checks, precision dimensional gauges, and eddy current or ultrasonic testers for defect detection, guaranteeing that every product meets or exceeds international standards such as ASTM, EN, and JIS, as well as specific customer requirements.
Pre-shipment inspection
We provide engineering-grade protective packaging for each and every product. Whether it's heavy copper tubes and plates, or precision rods, wires, and ultra-thin foils, we employ multi-layer composite protection: the inner layer uses scratch-resistant PE film and custom padding for physical isolation and cushioning; the middle layer is treated with moisture-proof sealing and includes desiccants; the outer layer utilizes reinforced wooden crates or high-strength waterproof wrapping film, depending on the shape and weight, for stabilization and protection. This ensures that the products withstand moisture, oxidation, and impact during long-distance sea or land transportation, arriving in perfect condition at your site. In terms of delivery, we commit to efficiency and reliability: standard specification products can be prepared and shipped within 7-15 working days, while customized products will also enter production scheduling promptly. We maintain full transparency throughout the process, allowing you to precisely control timelines and ensure your project proceeds as planned.
