Abstract

PURPOSE: To provide a sintered hard alloy having remarkably improved corrosion resistance and especially suitable for manufacturing decoration parts by adding a predetermined amount or more of one or more among Al, Si, Mn and B to a conventional sintered hard alloy contg. Co and/or NI and a hard component.
CONSTITUTION: The titled sintered hard alloy consists of, by wt., Co and/or Ni and 3W30% Mo, 0.1W5% Cr, 0.05W2% one or more among Al, Si, Mn and B, and the balance is one or more among WC, the carbides and the nitrides of the IVa and Va group transition metals in the periodic table. When the content of one or more among Al, Si, Mn and B is less than 0.05%, the desired superior corrosion resistance cannot be assured. ON the other hand, when the content exceeds 2%, the strength of the alloy is lowered. This sintered hard alloy is suitable for use as a material for decoration parts such as a watchcase.
