Abstract: front page image
(EN)The invention provides a Co-base alloy excellent in the resistance to corrosion from lead-free solder, particularly from molten lead-free Sn-Ag solder, and members of lead-free soldering apparatus which are made of the alloy. A Co-base alloy having a composition which contains Cr: 20.0 to 35.0%, Fe: 0.1 to 25.0%, C: 0.01 to 1.20%, Mn: 0.5 to 2.0%, and Si: 0.1 to 2.0%, and further contains, if necessary, (a) Ni: 1.0 to 24.0%, (b) La: 0.01 to 0.15% and/or Ce: 0.01 to 0.15% or (c) Mg: 0.001 to 0.05%, or two or more of (a) to (c), the balance being Co and unavoidable impurities; and members of lead-free soldering apparatus which are made of the alloy.
(FR)La présente invention concerne un alliage de Co dont la résistance à la corrosion due à une brasure sans plomb, en particulier à une brasure sans plomb Sn-Ag fondue est excellente, ainsi que des pièces d'un dispositif de soudure sans plomb fabriquées à partir de l'alliage. La présente invention concerne notamment un alliage de Co contenant Cr : 20,0 à 35,0 %, Fe : 0,1 à 25,0 %, C : 0,01 à 1,20 %, Mn : 0,5 à 2,0 %, et Si : 0,1 à 2,0 %, et contenant en outre, si nécessaire, (a), Ni : 1,0 à 24,0 %, (b) La : 0,01 à 0,15 % et/ou Ce : 0,01 à 0,15 % ou (c) Mg : 0,001 à 0,05 %, ou deux ou plus des éléments (a) à (c), le reste étant constitué de Co et des impuretés inévitables ; ainsi que des pièces d'un dispositif de soudure sans plomb fabriquées à partir de l'alliage.
(JA) 鉛フリーはんだ、特に溶融状態のSn-Ag系鉛フリーはんだに対する耐侵食性が優れたCo基合金およびそのCo基合金からなる鉛フリーはんだ付け装置部材を提供する。  Cr:20.0~35.0%、Fe:0.1~25.0%、C:0.01~1.20%、Mn:0.5~2.0%、Si:0.1~2.0%を含有し、さらに必要に応じて(a)Ni:1.0~24.0%、(b)La:0.01~0.15%およびCe:0.01~0.15%の内の1種または2種、(c)Mg:0.001~0.05%の内の1種または2種以上、または前記(a)~(c)の内の2種以上を含有し、残部がCoおよび不可避不純物からなる組成を有するCo基合金およびそのCo基合金からなる鉛フリーはんだ付け装置部材。
