Brass pipe has significant differences compared to purple copper pipe. First of all, from the composition, brass tube is mainly composed of copper and zinc, the copper content is higher but lower than the purple brass tube, the latter copper content of more than 90%, and contains a small amount of nickel, aluminum, tin and other elements, so it is more pure. In terms of hardness, brass tube is harder due to its higher proportion of copper and zinc alloy, which is suitable for scenes that need to withstand mechanical pressure; purple brass tube is relatively soft, easy to shape, and suitable for making fine art. In terms of density, brass tubes are slightly lower than copper tubes, a difference that also affects their application areas. Specifically, brass tube because of its excellent mechanical properties and electrical conductivity, often used in machinery manufacturing, electrical wiring, etc.; while the purple brass tube because of its good ductility and acoustics, in the field of music equipment, decorative materials and other areas of great splendor. Therefore, when choosing, according to the needs of the actual application scenarios, such as hardness requirements, electrical conductivity, aesthetics or acoustics, etc., to comprehensively consider which copper tube is more appropriate.
