An alloy metal, brass is a combination of copper and zinc. Depending on its specific type of composition, any one brass variation could include up to 60 different types of metal combinations. Brass is a multi-purpose metal with many uses including filtering liquid and gas as well as electrical and thermal conductivity. Known for its strength, hardness, wear-resistance, ductility and corrosion-resistance, brass can also be used as a decorative finish for home décor. Some of the latest home design trends include brass finished light fixtures, lamps, ceiling fixtures, and cabinet screens.   While the wire mesh industry uses may brass variants, one of the most common is 70/30 Brass, also known as Cartridge Brass. This type of brass has just the right ratio of strength to ductility, making it ideal for severely cold temperatures. Its higher zinc content makes 70/30 brass better at resisting corrosion than other types of brass. With the ability to be welded through soldering, gas shielded arc welding, brazing butt welding and spot welding, but not recommended for seam welding, cartridge brass is incredibly versatile.  Another popular type of brass in the wire mesh industry is Yellow Brass, which contains 65% copper and 35% Zinc. The higher zinc quantity gives this brass its golden coloring.  Red Brass, with 85% Copper and 15% Zinc, is exceptionally strong. Low Brass contains 80% Copper and 20% Zinc.
