A vehicle structure includes a first member that extends in a vehicle width direction, second members that extend in a front-back direction that are inserted in the front-back direction with respect to the first member, and third members that are arranged at end portions of the first member in the vehicle width direction and joined to the end portions.

Vehicle structure and method for manufacturing the same

A structural member includes an inner member and an outer member formed of a material different from that of the inner member, the outer member being positioned outside the inner member so as to surround the inner member and including a first adjacent surface adjacent to an outer surface of the inner member, wherein an insulator is disposed between the first adjacent surface and a second adjacent surface of the inner member, the second adjacent surface being adjacent to the first adjacent surface.

Structural member

An aluminum alloy substrate bears a first layer on at least one side thereof, and a second layer on at least part of the first layer. The first layer includes an oxide film containing Mg in a content of from 0.1 atomic percent to less than 30 atomic percent. The second layer contains siloxane bonds. The second layer is disposed in a mass of coating of from 0.1 mg/mto less than 30 mg/m. Assume that parallel polarized light is applied to the side bearing the first layer and the second layer at an incident angle of 75&#xb0;, and resulting data are analyzed by Fourier-transform infrared spectroscopy to give a spectrum. In the spectrum, a peak occurring adjacent to 1057 cmhas an area of 0.01 or more with respect to a base line drawn from 1026 cmto 1084 cm.

Aluminum alloy sheet, bonded object, and member for motor vehicle

An aluminum-alloy plate () equipped with an aluminum-alloy substrate () and an aluminum-oxide film () formed on the surface of the aluminum-alloy substrate (), wherein: the aluminum-oxide film () contains at least one type of additional element having a P-B ratio of 1.00 or more, zirconium in the amount of 0.01-10 atomic percent, and magnesium in the amount of 0.1 or more and less than 10 atomic percent; and the total amount of additional elements contained in the aluminum-oxide film () is 0.010-5.0 atomic percent. As a result, it is possible to provide: an aluminum-alloy plate which exhibits excellent post-degreasing-water-wettability stability even when in a high-temperature, high-humidity environment; and a joined body and a vehicle member which use the same.

Disclosed is an aluminum alloy clad material which includes a core material; a sacrificial anode material on one surface of the core material; and a filler material on the other surface of the core material and composed of an Al&#x2014;Si alloy, in which the core material contains 0.3 to 2.0 percent by mass of Mn, 0.15 to 1.6 percent by mass of Si, 0.1 to 1.0 percent by mass of Cu, and 0.1 to 1.0 percent by mass of Mg, with the remainder including Al and inevitable impurities, the sacrificial anode material contains 7.0 to 12.0 percent by mass of Zn, 0.3 to 1.8 percent by mass of Mn, and 0.3 to 1.2 percent by mass of Si, with the remainder including Al and inevitable impurities, and has a thickness of 10 to 30 &#x3bc;m. The sacrificial anode material shows resistance to both local corrosion and general corrosion.
