Abstract : The notch-bend strength of ten nonferrous alloys was determined. Four-inch-square specimens of seven cast copper-base alloys and a cast nickel-copper alloy showed extensive yielding prior to fracture. Similar specimens of wrought 7075-T6 and extruded 2024-T4 aluminum alloys failed in a brittle manner. It is concluded that the seven cast copper-base alloys and the cast nickel-copper alloy are notch tough and thus not prone to brittle fracture in air when used in sections up through 4 inches thick.
