Abstract

The invention discloses a nickel brass strip. The nickel brass strip comprises, by weight percentage, 67%-73% of Cu, 2%-4.5% of Ni, 0.003%-0.015% of P, not larger than 0.01% of Pb, not larger than 0.012% of Fe and the balance Zn and inevitable impurities. According to the nickel brass strip, by optimizing the components and the content of the nickel brass strip, the corrosion resistance and wear resistance of the nickel brass strip are improved remarkably. The invention further provides a manufacturing of the nickel brass strip.

Description

technical field [0001] The invention relates to the technical field of copper material processing, in particular to a nickel brass strip and a preparation method thereof. Background technique [0002] With the continuous expansion of the application range of copper alloy products, higher and higher performance requirements are put forward for the performance of copper alloy strips. The corrosion resistance and wear resistance of the general-purpose nickel-brass alloys are increasingly unable to meet the material applications. At the same time, most of them are produced by horizontal continuous casting. [0003] Therefore, how to provide a nickel brass with high corrosion resistance and wear resistance is a technical problem that those skilled in the art need to solve urgently. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a kind of nickel brass strip, the corrosion resistance and wear resistance of this nickel brass...
