摘要： The invention relates to a copper-tin alloy, comprising 0.2 to 0.8% by weight Sn, 0.1 to 0.6% by weight Ni and/or Co, 0 to 0.05% by weight Zn, 0 to 0.2% by weight Fe, 0.008 to 0.05% by weight P, and also Cu as remainder. The invention furthermore relates to a corresponding composite material having a base material made of such an alloy and also to suitable uses thereof. The technological and physical properties are comparable with those of a CuFe2P alloy. However, the alloy according to the invention and also a tin-plated composite material made thereof can be readily recycled.

摘要： A process of manufacturing a roll suitable for use in a rolling mill, the roll having a cylindrical barrel middle section and a neck at each end of the barrel, wherein the barrel and necks are of different material compositions, by remelting an electrode having a central region corresponding in mass and composition of materials to that desired for the barrel of the roll, two end regions corresponding in mass and composition of materials to that desired for the necks of the roll and a transition region disposed between the central region and each end region, each transition region including the material of the barrel and at least one further material. An electroslag remelting process is used in a water cooled mold. The mold is composed of at least two parts and defines a cavity approximating the final outlines of the roll. The mold has tapered transition regions between a part of the cavity corresponding to the barrel and the constricted cavity regions corresponding to the necks. The roll produced in the remelting step is then heat treated and finished.
