In addition, a Cu—Fe—P alloy sheet with relatively small Fe content is provided with a texture in which a ratio (I(200)/I(220)) of intensity of diffraction of (I(200)) from the (200) plane in the sheet surface to intensity of diffraction of (I(220)) from the (220) plane, is 0.3 or less. In addition, a Cu—Fe—P alloy sheet with relatively small Fe content is provided with a texture in which the orientation distribution density of Brass orientation measured by the crystal orientation analysis method using an EBSP by an FE-SEM, is 25% or more; and an average grain size in the sheet is 6.0 μm or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Copper alloy sheet for electric and electronic part","description":"A shear plane ratio is reduced by a dislocation density in which a value obtained by dividing the half-value width β of the intensity of diffraction of {311} plane in the surface of a Cu—Fe—P alloy sh","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9644250","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
