Title:
TITANIUM-COPPER FOR ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2011/065188
Kind Code:
A1
Abstract:
Provided is titanium-copper which has excellent strength and bendability. The titanium-copper is a copper alloy for electronic components which contains 2.0-4.0 mass% Ti, the remainder comprising copper and incidental impurities. The intensity peak of X-ray diffraction from the {220} crystal plane in a rolled surface of the copper alloy has a half-value width β{220} which satisfies the relationship 3.0≤β{220}/β0{220}≤6.0, wherein β0{220} is the half-value width of the intensity peak of X-ray diffraction from the {220} crystal plane of a standard powder of pure copper. The copper alloy, in a structure examination of a section parallel to the rolling direction, has an average crystal-grain diameter of 30 µm or smaller in terms of equivalent-circle diameter.
