In the United States, it usually has yellow or light orange colored printing, common sizes being 1 + 1 ⁄ 4, 1 + 1 ⁄ 2, and 2-inch copper tube size. Types K and L are generally available in both hard drawn straight sections and in rolls of soft anealed tubing, whereas type M and DWV are usually only available in hard drawn straight sections.
Admiralty metal, a 70% Cu-30% Zn yellow brass alloy with 1% tin added to improve corrosion resistance, was introduced in 1890 for seawater service. [2] By the 1920s, a 70% Cu-30% Ni alloy was developed for naval condensers. Soon afterwards, a 2% manganese and 2% iron copper alloy was introduced for better erosion resistance. A 90% Cu-10% Ni ...
Leaded copper is a metal alloy of copper with lead. A small amount of lead makes the copper easier to machine. Alloys with a larger amount of lead are used for bearings. Brass and bronze alloys of copper may have lead added and are then also sometimes referred to as leaded copper alloys. [1] Leaded copper and its alloys have been used since ...

cassettes (typically made from 1.0 mm up to 1.5 mm thick copper sheet): largest-format cladding elements, more subframing is needed: can be 900 mm x nominal 4000 mm length. When selecting size of a cladding element, take wind-loadings into account, and also consider the standard sizes available of the sheet (or coil) pre-material, to minimise ...

Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).
