Detailed Product Description

High Hardness ASTM B111 C71640 Copper Nickel Alloy Seamless Tube 

 

Introduction of C71640

 

First of all, C71640 iron-nickel copper has a relatively high hardness and also has good strength and toughness. This allows it to maintain a relatively stable shape despite being subjected to large stresses and is less prone to plastic deformation or fracture. This is very important because in many industrial fields, such as aviation, automobiles, machinery manufacturing and other high-stress environments, it is often necessary to use this kind of metal material with excellent performance to ensure the quality and ety of products.

 

Secondly, C71640 iron-nickel copper has better corrosion resistance. It can be stored in the air for a long time and will not be affected by oxidation or corrosion. At the same time, it can also resist the erosion of many chemical substances, so it can be widely used in chemical industry, marine engineering and other fields.

 

In addition, C71640 iron-nickel copper also has good electrical and thermal conductivity.

In the electronics industry, materials with good electrical conductivity need to be used to ensure the normal operation of circuits or devices.

In the heat treatment industry, materials with good thermal conductivity need to be used to ensure that products will not deform or burn out under high temperatures. BFe30-2-2 (C71640) iron-nickel copper can meet these requirements and is therefore widely used in related fields.

Why Are Copper Nickel Tubing Used In Heat Exchangers?


Copper nickel tubing is designed with a superior chemical composition allowing them to work well in harsh conditions. These tubes can handle different pressures and temperatures, which is very essential for running heat exchangers. The tubing devices have excellent fatigue strength and mechanical properties, allowing them to withstand the different conditions in this system.
