What is ASTM B111 C68700 tube?
B111 C68700 copper alloy seamless condenser tube is a high-performance copper alloy tube that is widely used in refrigeration equipment such as condensers and evaporators. Due to its excellent thermal conductivity, corrosion resistance and good mechanical properties, it has been widely used in the refrigeration industry.
This copper alloy is mainly composed of copper, aluminum, nickel and other elements, of which copper has the highest content, reaching more than 95%. The addition of aluminum and nickel not only improves the strength and hardness of copper alloy, but also enhances its corrosion resistance. In addition, a small amount of iron, manganese, silicon and other elements are added to the copper alloy to further improve its overall performance.
