What causes brass fittings to corrode?
One, when water flows through the high zinc brass fittings, the zinc in the fittings leaches out of the fittings. This leaching weakens the fittings due to a process called dezincification.
Do brass fittings corrode?
They are corrosion resistant – Brass doesn’t rust and it is highly resistant to corrosion. Rust and corrosion rapidly speed up the natural wear and tear process on the fitting, so when you are looking for long-lasting fittings, brass is the best material for the job.
Are brass fittings safe for water?
The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014.
How long does it take for brass to corrode?
Outside of situations where it’s submerged in water, brass is a great metal for outdoor applications due to its amazing endurance. That rapid change to blue-green isn’t a sign of decay — in the right conditions brass can last more than 1,000 years!
What does oxidized brass look like?
Oxidized brass is typically blackish, green or blue, and hardens like a thick crust over the surface of the brass. This coating typically flakes off and can be removed to reveal the shiny brass surface. Oxidation has no effect on the integrity of the brass the way corrosion does.
How long will brass fittings last?
Brass: An allow of copper and zinc, brass piping is slightly less common than copper piping but has a slightly longer lifespan. Generally, brass pipes can survive between 80-100 years.
Does brass degrade over time?
Copper, Bronze and Brass
Copper oxidizes over time to form a green patina, which actually protects the metal from further corrosion.
Does soft water corrode brass?
This study concluded there was no significant difference in the corrosion rates for brass, copper, mild steel and stainless steel between the two rigs. There was initially a higher rate of corrosion of aluminum from ion-exchange softened water, but this decreased continually over time.

Does brass dissolve in water?
Brass, a common alloy of copper and zinc with lesser amounts of lead and tin, is ubiquitous in water distribution systems. Because the zinc component is relatively easily lost to the water, brass corrosion is ever present and can lead to serious failures in of system components.
What corrodes brass fast?
Salt, in particular, tarnishes brass quickly and must be kept away from brass intended to be kept shiny. Chemicals in rainwater, tap water and air, as well as those found on our fingers and in food, are also corrosive.
How do you stop brass oxidation?
Brass will automatically start to tarnish if exposed to oxygen. The only way to prevent polished brass from tarnishing is to coat it with a layer of clear sealer that will prevent air from reaching the brass itself. Many brass surfaces come with this finish originally, but it can wear down over time.
Why does brass turn white?
Brass planters are made of copper and zinc for a finished product that is bright and shiny. When brass oxidizes in the environment, it accumulates a white film that is very unattractive on your planters. Cleaning brass is simple, though it can require a little elbow grease if the oxidation is thick on the surface.
Does brass turn black?
Brass turns “black” when cleaning due to over-use and misuse of polish. The biggest challenge to the upkeep of most metals, including brass, is the removal and inhibition of tarnish. All substances, especially metals, oxidize when exposed to air.
