Messingbrass

Messingbrass is a term used in German-speaking contexts to refer to brass, a family of copper-zinc alloys. In English, the term is rarely used; brass is the standard designation. The alloy is defined by zinc content, which gives brass its characteristic color and properties, varying from a reddish hue to a yellowish tone depending on composition and temper.

Brass compositions vary widely, but zinc content generally ranges from about 5% to 45% by weight, with the balance copper. Small additions of lead, tin, or aluminum are sometimes made to tailor machinability, strength, or corrosion resistance. Common commercial brasses include low-zinc red brass and higher-zinc yellow brass; many grades exist for plumbing fittings, architectural hardware, and decorative items. Leaded brasses improve machinability but can affect strength and friction.

Brass alloys are generally more malleable and easier to machine than pure copper. They exhibit good formability, wear resistance, and corrosion resistance in many environments, though they can be susceptible to dezincification in certain waters. They are non-magnetic and have higher electrical conductivity than many metals, though lower than pure copper.

Brass is produced by melting copper and zinc and combining them in controlled proportions, then casting or hot/cold working the alloy. It is used in plumbing fittings, valves, fasteners, musical instruments, architectural hardware, decorative items, and electrical components. Finishing options include polishing, lacquering, and plating.
