Description

At Bronmetal we supply high quality brass tubes for industrial and decorative applications.

We have the capacity to supply brass tubes in round, square, grooved and rectangular format.

Brass tubes have high resistance to corrosion, leading to their application in bathroom fittings and pipe connections for water and other fluids.

Among the main properties of brass, we can highlight:

It has greater machinability and ductility than other alloys.
Solidity against wear.
It has high electrical conductivity.
It has excellent properties for welding.
Brass is a metal that can easily be recycled. Its waste can be separated with ease and re-cast as many times as necessary.
It does not alter at extreme temperatures, between -100ºC and 200ºC and it does not fade in light.
It has high resistance to corrosion and rust, even in saline conditions.
