Steel wire for hose reinforcement is also called hose wire, brass-plated steel wire, rubber tube wire, or brass rubber tube wire. It is used as the reinforcement layer of the rubber hose and wrapped plastic hose in the form of braid or spirally wrapped. These high-pressure rubber hoses could sustain high pressure and high impact, and they can be used for machinery, aviation, ocean, oil drilling and some other special occasions. The surface of steel wire for hose reinforcement is plated a layer of uniform copper zinc alloy. The ratio of copper to zinc is 68±4%:32±4%.
