摘要： A wear-resistant copper-based alloy includes 10.0 to 30.0% by weight Ni, 2.0 to 15.0% by weight Fe, 2.0 to 15.0% by weight Co, 0.5 to 5.0% by weight Si, 1.0 to 10.0% by weight Cr, 2.0 to 15.0% by weight at least one first optional element selected from the group consisting of Mo, Ti, Zr, Nb and V, at least one second optional element selected from the group consisting of C and O, and the balance of Cu and inevitable impurities. A carbon content "X" and an oxygen content "Y" satisfy the following relationships; namely: 0.ltoreq."X".ltoreq.0.5, 0.ltoreq."Y".ltoreq.0.05, and "Y".gtoreq.(-0.8)("X")+0.04. The wear-resistant copper-based alloy enables to improve the toughness of weld bead, and to inhibit weld bead from cracking effectively in the solidifying process of a building-up operation.

摘要： The object of the present invention is to provide at a low cost iron-base heat- and corrosion-resistant brazing material which make it possible to braze parts made of a base metal selected from among various stainless steels, particularly ferritic stainless steels, at a practical temperature (of 1120° C. or lower) and are excellent in the wetting property against the base metal and which can attain excellent resistance to corrosion by sulfuric acid or nitric acid and high strength without coarsening the structure of the base metal. The iron-base heat- and corrosion-resistant brazing material is characterized by comprising 30 to 75 wt % of Fe, 35 wt % or less of Ni and 5 to 20 wt % of Cr in a total amount of Ni and Cr of 15 to 50 wt %, and 7 wt % or less of Si and 4 to 10 wt % of P in a total amount of Si and P of 9 to 13 wt %. The iron-base heat- and corrosion-resistant brazing material further comprising 0.5 to 5 wt % of Mo and/or 0.3 to 5 wt % of Cu in a total amount of Mo and Cu of 1 to 7 wt % is more preferable.
