ASTM B111 Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes and Ferrule Stock.
ASTM B111 C70400 95-5 Copper-Nickel Seamless Tubes up to 3 1 ⁄ 8 in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.
Core Features of Astm B111 C70400 electro-heat up copper pipe
C70400 (UNS designation) is a copper-nickel alloy (commonly known as "white copper") with a copper base (90%-93%), nickel (5%-7%), iron (1%-1.8%), and trace amounts of manganese and zinc. Its core properties include:
Corrosion Resistance: Excellent performance in seawater, salt spray, and acidic media, with an annual corrosion rate of less than 0.1mm, making it particularly suitable for marine environments.
Mechanical Properties: Tensile strength of 379-586 MPa, yield strength of 120-379 MPa, and elongation of 15%-40%, combining high strength with good ductility.
Physical Properties: Density of 8.83 g/cm³, thermal conductivity of 50 W/m·K, and electrical conductivity of 17% IACS (International Annealed Copper Standard), achieving a balanced balance between thermal and electrical conductivity.
Application Areas of Astm B111 C70400 Heat Sink Copper Heat Pipe
Marine Engineering
Shipbuilding: Seawater pipelines, propeller shafts, and heat exchanger tube bundles, with salt spray corrosion resistance and a lifespan exceeding 15 years.
Offshore Platforms: Desalination plant flanges and deep-sea pipeline joints, resistant to high-pressure corrosion.
Energy and Chemical Industry
Petrochemical Equipment: Cracking reactor condensers and pump and valve components, resistant to acidic oil and gas media.
Power Systems: Cable sheaths and connectors, balancing electrical conductivity and environmental protection.
High-End Manufacturing
Aerospace: Hydraulic pipelines and engine cooling components, meeting lightweight and heat-resistant requirements.
Refrigeration Industry: Air conditioning heat exchanger fins, with 20% higher thermal conductivity than aluminum alloys.
