摘要: 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 has sufficient fluidity infiltrate and fill at least 90% of interstices resulting in a composite article having superior strength toughness. This can be used drilling bits other cutting tools, either as support body for elements or element itself.
