There are several important considerations for those selecting metal pipework materials for domestic and commercial plumbing applications. You need excellent corrosion resistance for a start, but if your pipes are to be exposed, they also need to be visually attractive. Finally, they must be durable for their purpose and in the environment intended for their use.
The two main options to choose from are brass and copper pipe.
How to choose between copper and brass pipe
Environmental considerations are obviously a major factor when deciding between these options. In a typical domestic installation, both brass and copper are equally appropriate for circulating fresh water, but it is useful to note that copper pipe will oxidise and change colour over time, while brass will not, so if the pipework is to be exposed, brass may be a longer lasting and more suitable option.
When it comes to corrosion resistance, brass again has the upper hand, coping well in moist environments, even when presented with acidic water or high salt levels. Brass is a stronger material than copper, although copper is more malleable, making it easier to work with, particularly when using specialist push fit connectors, such as those offered by watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems/.
In conclusion
The pleasing patina offered by copper pipework can degrade over time, so although it is easier to install and will offer similar levels of corrosion resistance to brass in a typical domestic installation, brass pipework is more resilient and may in certain instances represent better value for money in the long term.
