Title:
ALUMINUM ALLOY-MADE VEHICULAR WHEEL
Document Type and Number:
Japanese Patent JP2017039986
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular wheel made of an aluminum alloy combining high strength (0.2% proof stress) with high toughness( elongation).SOLUTION: There is provided the vehicular wheel made of an aluminum alloy containing Si of 6.5 to 11.8 mass%, Mg of 0.20 to 0.45 mass%, one or more kind selected from a group consisting of Cu, Zn, Fe, Mn and Ti of 0.1 to 1.5 mass% and the balance Al with inevitable impurities. In the vehicular wheel made of an aluminum alloy, a reduction rate of X ray intensity ((Sav-Smin)/Sav×100) is 15% or less, where Sav is an average value of X ray intensity of Si measured in primary crystal Al of the aluminum alloy and Smin is the lowest X ray intensity in the primary crystal Al.SELECTED DRAWING: Figure 1
