Abstract: front page image
(EN) Provided are: a Cu alloy with excellent machinability; and a Cu alloy extruded pipe member and Cu alloy synchronizer ring made of same. The present invention is: a Cu alloy which has excellent machinability and in which the amount of intermetallic compounds formed is reduced and fine carbides have been dispersed in the base, said Cu alloy containing, in mass%, Zn: 25% to 43%, Al: 2.0% to 8.0%, Ti: 0.10% to 5.0%, Cr: 0.010% to 0.040%, C: 0.0005% to 0.010%, and 1.0% to 5.0% total of one or more selected from among Fe, Ni and Co, the balance being made of Cu and unavoidable impurities; and a Cu alloy extruded pipe member and Cu alloy synchronizer ring made of same.
(FR) L'invention concerne un alliage de Cu ayant une excellente usinabilité et un élément de tuyau extrudé en alliage de Cu et une bague de synchroniseur en alliage de Cu faits de celui-ci. La présente invention concerne : un alliage de Cu ayant une excellente usinabilité et dans lequel la quantité de composés intermétalliques formés est réduite et des carbures fins ont été dispersés dans la base, ledit alliage de Cu contenant, en % en masse, de 25 % à 43 % de Zn, de 2,0 % à 8,0 % d'Al, de 0,10 % à 5,0 % de Ti, de 0,010 % à 0,040 % de Cr, de 0,0005 % à 0,010 % de C et de 1,0 % à 5,0 % au total d'un ou de plusieurs éléments choisis parmi Fe, Ni et Co, le reste étant constitué de Cu et des impuretés inévitables; en un élément de tuyau extrudé en alliage de Cu et une bague de synchroniseur en alliage de Cu faits de celui-ci.
(JA) すぐれた被削性を備えるCu合金およびこれからなるCu合金製押出しパイプ部材、Cu合金製シンクロナイザーリングを提供する。質量%で、Zn:25%以上43%以下、Al:2.0%以上8.0%以下、Ti:0.10%以上5.0%以下、Cr:0.010%以上0.040%以下、C:0.0005%以上0.010%以下、Fe、NiおよびCoの内から選ばれる1種または2種以上を合計で1.0%以上5.0%以下含有し、残部Cuおよび不可避不純物からなり、金属間化合物の生成量を低減し、素地中に微細炭化物を分散させた被削性に優れたCu合金、および、これからなるCu合金製押出しパイプ部材、Cu合金製シンクロナイザーリング。
