Copper Alloy Engineering Tube

Copper alloys have been designed to match capabilities to needs and are amongst the oldest materials in the service of man.

Even small additions of a second element can significantly effect a property.

The alloying elements employed to alter the characteristics of pure copper used for copper alloy engineering tubing impart differing characteristics, often in combination: strength, temperature capabilities, machining properties or corrosion resistance. They all retain to some degree basic properties of copper: ductility, thermal and electrical conductivity.

All the alloys are fairly strong: high strength alloys can be treated to achieve well over 500 MPa (aluminium brass reaches 550 and phosphor bronze over 650 MPa).
