COMPOSITE ARTICLES COMPRISING SPINODAL COPPER-NICKEL-TIN-MANGANESE-PHOSPHORUS ALLOY MATRIX MATERIAL

A spinodal copper-nickel-tin-manganese alloy is disclosed that contains from 0.001 to about 2 weight percent phosphorus. When combined with small hard particles, the alloy has sufficient fluidity to infiltrate and fill at least 90% of the interstices of the hard particles, resulting in a composite a...

More Information
Summary:A spinodal copper-nickel-tin-manganese alloy is disclosed that contains from 0.001 to about 2 weight percent phosphorus. When combined with small hard particles, the alloy has sufficient fluidity to infiltrate and fill at least 90% of the interstices of the hard particles, resulting in a composite article having superior strength and toughness. This composite article can be used in drilling bits and other cutting tools, either as a support body for cutting elements or as the cutting element itself.
