Ductility of brass copper but only after cost manufacturing and cheaper refined copper a lot! (Copper with highest purity is created by means of dissociated from the copper ore, ductility and excellent electrical conductivity.)
Also so that brass is used quite commonly and especially gas processing instrument that uses reed. Including harmonica jog! After some time, the ad learn discovered that each type of harmonica, each type, line of each company harmonica reed, the carriers will be crafted brass. However brass also many types and colors vary depending on the amount of zinc contained in its provisions. Specifically:
