Copper and copper alloy tube is in demand for use in pneumatic controls, thermostatic controls, bourdon tube for pressure gauges, temperature limit switches, solenoid valves as well as reversing valves for heat pumps.

Precision copper alloy bourdon tube is used for manufacturing pressure gauges and pressure controls.  Named for the physical operating principal to which it is applied, bourdon tube becomes the primary sensing element in mechanical pressure gauges.  Critical parameters include consistent dimensional stability, temper consistency, and cleanliness to provide the optimum gauge calibration and performance.
