ASME SB111 C70600 O61 Copper Nickel Tube for Condenser Heat Exchanger

Product Specification

ASME SB111 C70600 O61 Copper Nickel Tube for Condenser Heat Exchanger
 

ASME SB111 standard specifies the manufacturing process, material selection, quality control and other aspects of white copper seamless tube in detail, ensuring the reliability and stability of the product. At the same time, the standard also emphasizes the corrosion resistance of the product, and evaluates the corrosion resistance of seamless tubes in different environments through a series of strict test methods.

ASME SB111 C70600 copper nickel tube is mainly composed of copper, nickel, iron and manganese. Among them, the nickel content is about 9.0%-11.0%, the iron content is between 1.0%-1.8%, the manganese content does not exceed 1.0%, the zinc content does not exceed 1.0%, and the lead content does not exceed 0.05%. Other elements such as phosphorus and carbon also have strict content limits.

ASME SB111 C70600 Copper Nickel Tube Mechanical properties

• Tensile strength: The tensile strength of ASME SB111 C70600 copper nickel tube is usually between 275MPa and 550MPa, depending on its heat treatment state and processing method. Higher tensile strength means that the alloy can resist breaking at a higher maximum stress when subjected to tensile force, so it is suitable for environments with high pressure.
• Yield strength: Yield strength is the maximum stress that a material can withstand before plastic deformation occurs. The yield strength of ASME SB111 C70600 copper nickel tube is usually between 105MPa and 350MPa, which is also affected by heat treatment and processing methods. This property ensures the stability of the material when subjected to stress.
• Elongation: The elongation of ASME SB111 C70600 copper nickel tube is generally between 20% and 40% (some say about 30%), showing good plasticity. This means that the alloy can undergo large plastic deformation without breaking when subjected to external force, and is suitable for cold working and shape change.
• Hardness: The Vickers hardness of ASME SB111 C70600 copper nickel tube is usually between 160HV and 210HV, indicating that it has good wear resistance and scratch resistance. Under the same conditions, the Brinell hardness of C70600 copper nickel tube is about 80HB to 150HB (some say about 150HB), which ensures its long-term stability in a strong wear environment.
