Product Copper Alloys Pipes & Tubes
Copper alloys are metals made by combining copper with other elements such as zinc, tin, nickel, or aluminum to enhance specific properties. These alloys leverage copper's excellent thermal and electrical conductivity, resistance to corrosion, and malleability, while the added elements improve strength, wear resistance, and other characteristics. Pipes and tubes made from copper alloys are used across various industries, including plumbing, HVAC, aerospace, and marine applications, due to their durability and superior performance in challenging environments.

Mechanical Properties
The mechanical properties of copper alloys vary by type but generally include high tensile strength, excellent fatigue resistance, and good ductility. For example, brass offers good machinability, while bronze provides superior wear resistance.
Dimensions
Copper alloy pipes and tubes are available in various sizes, including outer diameter, wall thickness, and length. Standard dimensions are governed by industry standards, but custom sizes can also be manufactured.
Thermal Conductivity
Copper alloys are known for their high thermal conductivity, which is beneficial for applications such as heat exchangers and cooling systems. The exact thermal conductivity depends on the specific alloy composition.
Corrosion Resistance
Copper alloys are renowned for their corrosion resistance. The level of resistance varies with the alloy type; for instance, copper-nickel alloys are highly resistant to seawater, while brass is more susceptible to dezincification.
Surface Finish
The surface finish of copper alloy pipes and tubes can vary from smooth and polished to rougher textures, depending on the manufacturing process and application requirements.
Standards and Grades
Copper alloy pipes and tubes are manufactured according to industry standards such as ASTM, ISO, and DIN. Common grades include C11000 (Electrolytic Tough Pitch Copper), C26000 (Brass), and C62200 (Aluminum Bronze).
Weldability and Machinability
Copper alloys generally offer good weldability and machinability. Brass is particularly noted for its machinability, while bronze is valued for its durability and ability to withstand harsh conditions.
