Round extruded/calibrated bronze tubes

Extruded or calibrated round bronze tube. Manufactured for decorative applications.

Data sheet: Round extruded/calibrated bronze tubes

The bronze pipe we supply at Bronmetal is manufactured from quality materials and designed especially for decorative applications. They are characterised by good mechanical strength and are able to withstand heavy loads and high pressures, making them suitable for structural applications and for transporting fluids under pressure. Furthermore, although it depends on the type of alloy, in general, bronze tubes are easy to machine, allowing the creation of complex and customised parts without too much difficulty.

Calibrated tubes have very close tolerances on their outer dimensions, which ensures high accuracy and uniformity along the entire length of the tube. This is especially important in applications where an exact fit is required.
