Messinki

Messinki is the Finnish term for brass, an alloy of copper and zinc. Brass alloys vary in zinc content, with many common grades containing roughly 60% copper and 40% zinc. Other compositions yield different color, strength, and ductility, and there are subtypes such as red brass (lower zinc) and high-zinc brasses. The naming and classification of brass reflect its compositional ranges rather than a single fixed formula.

Brass is typically yellowish to golden in color and tends to be more malleable and machinable than pure copper. The addition of zinc alters properties such as strength, hardness, and corrosion resistance. Brass conducts electricity and heat somewhat below copper, and its resistance to corrosion depends on the environment. In some environments, dezincification can occur, gradually removing zinc and weakening the alloy. Brass is generally easier to form and cast than many other metals, making it suitable for a wide range of manufactured parts.

Common applications of messinki include architectural hardware such as doorknobs, lock bodies, and fittings, plumbing components, decorative items, and musical instruments. It is also used in coins in certain regions and historical contexts. Brass can be finished through polishing, plating, or patination to achieve various aesthetic effects. Maintenance typically involves cleaning to prevent tarnish, which appears as a dull dark film on the surface and can be removed by polishing or chemical cleaners. Overall, messinki combines appealing appearance with favorable manufacturability for a broad array of everyday and artistic uses.
