Patent ID: 7241327

Claim:
An iron-based sintered alloy with dispersed hard particles comprising: a matrix comprising, by weight, 0.4 to 2% silicon (Si), 2 to 12% nickel (Ni), 3 to 12% molybdenum (Mo), 0.5 to 5% chromium (Cr), 0.6 to 4% vanadium (V), 0.1 to 3% niobium (Nb), 0.5 to 2% carbon (C), and the reminder of iron (Fe); and hard particles dispersed in the matrix in an amount in the range of 3 to 20% based on the entire alloy, the hard particle comprising 60 to 70% molybdenum (Mo), 0.3 to 1% boron (B), 0.1% or less carbon (C), and the remainder of iron (Fe), the iron-based sintered alloy being produced by sintering the matrix containing the hard particles.
