Should I use a dielectric union or brass nipple to connect copper

Brass is a copper/zinc alloy, so a brass nipple qualifies as a type of "copper alloy fitting" that is cited as acceptable by the code. While a dielectric union (shown above) provides a break in electrical conductivity that theoretically would be best, most plumbers prefer a brass fitting. "In my experience they are better than dielectic ...

BBs | Steel & Lead | .177 4.5mm | Pyramyd AIR

Copper-plated steel BBs can be used in steel, brass, or copper airguns without hurting the copper finish (the copper coating will not flake off). The copper plating is so thin you cannot see it with the naked eye. .177 caliber, copper-plated steel BBs are made by first making copper-free steel BBs, then copper is applied to the steel.

What's the Difference Between Bronze and Brass Valves?

This makes it easy to cast, forge, heat extrude, or cold draw. Brass is very corrosion-resistant, much like bronze, but is susceptible to breaking down when exposed to high levels of chlorine. The main benefit of brass valves over bronze is the much lower levels of lead present in the metal. This makes brass safe for drinking water in most ...
