The difference between pipes and tubes is a matter of sizing. For intance, PVC pipe for plumbing applications and galvanized steel pipe are measured in iron pipe size (IPS). Copper tube, CPVC, PeX and other tubing is measured nominally, basically an average diameter. These sizing schemes allow for universal adaptation of transitional fittings.

Red Brass is an alloy comprised of more than 80% copper, 8-10% of tin, 2-4% of zinc and a very small quantity of lead. The huge quantity of copper content gives the metal a reddish color. It may occasionally contain grey-black or black spots that are developed due to its exposure to silver nitrate.

Copper surfaces exposed to air gradually tarnish to a dull, brownish color. If water and air are present, copper will slowly corrode to form the carbonate verdigris often seen on roofs and statues. Uses of Copper. As a result of its excellent electrical conductivity, copper's most common use is in electrical equipment such as wiring and motors.

Copper was the first metal to be used to make weapons and tools. Mining and smelting skills spread from Asia Minor to Central Europe 4000 years BC. Around 3000 BC, high-ranking men owned a copper axe, which was often buried with them. A copper axe was used not only for woodworking and felling trees but was also a powerful close-combat weapon.
