衛(wèi)浴行業(yè)用無鉛易切削鉍黃銅的研究進(jìn)展衛(wèi)浴行業(yè)用無鉛易切削鉍黃銅的研究進(jìn)展Research Progress of Free-Cutting Unleaded Bismuth Brass for Sanitary Ware Industry 從產(chǎn)業(yè)化角度,綜述了衛(wèi)浴行業(yè)用無鉛易切削鉍黃銅的研究進(jìn)展,重點介紹了鉍硒黃銅、鉍錫黃銅和鉍鋁黃銅等3種鉍黃銅的化學(xué)成分、性能和生產(chǎn)應(yīng)用情況。鉍黃銅可部分替代傳統(tǒng)鉛黃銅用于衛(wèi)浴五金產(chǎn)品,其較成熟的生產(chǎn)方法有鑄造、直接機加工、冷彎,而熱沖壓、熱鍛、焊接等方法還有待進(jìn)一步的研究。今后的研究重點應(yīng)集中在改善鉍黃銅的熱沖壓性能上。 The research progress of free-cutting unleaded bismuth brass for sanitary ware industry is summarized from the point of industrialization. The chemical composition, property and practical production of three types of bismuth brasses including bismuth-selenium brass, bismuth-tin brass and bismuth-aluminum brass are highlighted. The bismuth brass can partially replace the traditional lead brass for the sanitary ware products. The relatively mature production methods are casting, direct machining and cold bending, while the methods such as hot stamping, hot forging and welding still remain to be further studied. The future research should be focused on the improvement of the hot punching property of bismuth brass. 全文下載:https://pan.baidu.com/s/1pL7JZxp
