Brass is a class of metal alloys composed predominantly of copper and zinc. Variations in the percent composition of primary elements and the addition of other elements such as tin and lead allow for a wide variety of properties. Brass is favored for its attractive gold appearance, low melting point, resistance to oxidation, and non-ferrous (non-magnetic) properties. Brass readily absorbs the 1.06 micron wavelength of the fiber laser, allowing for both marking and cutting applications. Laser marking of brass results in the creation of a bold dark mark. The fiber laser is capable of cleanly cutting intricate patterns in thin brass (up 0.005 inches or 125 microns).
