Abstract: Provided is a 6000-series aluminum alloy sheet suitable for a vehicle structural component. The Mg content and the Si content of an Al—Mg—Si aluminum alloy sheet are balanced in a special relationship, particularly cube orientation is increased as a texture in a surface region of the sheet, and the yield ratio of the sheet is reduced, thereby high strength of 0.2% proof stress of 220 MPa or more required for the vehicle structural component is ensured, and crashworthiness evaluated by a VDA bending test is improved.

Abstract: A vehicular glass antenna is provided. The antenna includes an AM broadcast wave receiving antenna having a plurality of horizontal strips and at least two vertical strips with an AM feed point between the vertical strips on the uppermost horizontal strip or through a line extending from the uppermost horizontal strip, and two FM broadcast wave receiving antennas extending from two FM feed points provided above uppermost horizontal strip of the AM antenna along a part of an outermost portion of the AM broadcast wave receiving antenna. The FM antennas extend in opposite clockwise and counterclockwise directions. The FM antennas have a substantially U-shape surrounding the ends of the AM antenna horizontal strips on their respective sides, and include a second horizontal strip adjacent to the horizontal strips of the AM antenna to achieve capacitive coupling.

Abstract: Disclosed is an Al—Mg—Si aluminum alloy sheet that can prevent ridging marks during press forming and has good reproducibility even with stricter fabricating conditions. In an Al—Mg—Si aluminum alloy sheet of a specific composition, hot rolling is performed on the basis of a set relationship between the rolling start temperature Ts and the rolling finish temperature Tf° C., whereby the relationship of the cube orientation distribution profile in the horizontal direction of the sheet with the cube orientation alone or another crystal orientation distribution profile at various locations in the depth direction of the sheet is made more uniform, suppressing the appearance of ridging marks that develop during sheet press forming.

Abstract: An aluminum alloy sheet of specific Al—Mg—Si composition, which, owing to preliminary aging treatment under adequate conditions, has a specific metallographic structure in which there are a large number of clusters of specific size (each being an aggregate of atoms) expressed in terms of number density, which, when observed under a transmission electron microscope of 1,000,000 magnifications, appear as dark contrast in the bright field image. It is superior in paint baking hardenability and is invulnerable to room temperature aging during storage for a comparatively long period of 1 to 4 months.

Abstract: There is provided an antenna for a vehicle which is formed on a space above defogging heater strips of a rear window glass of the vehicle.

Abstract: An Al—Mg—Si type alloy sheet contains 0.2 to 1.5 wt % of Mg and 0.2 to 1.5 wt % of Si. The sheet has textures in which orientation distribution density of Goss orientation is 3 or lower, orientation distribution density of PP orientation is 3 or lower and orientation distribution density of Brass orientation is 3 or lower. The sheet may contain 0.01 to 1.5 wt % in total weight of one or more elements selected from the group consisting of Mn, Cr, Fe, Zr, V and Ti. The sheet may further contain 0.01 to 1.5 wt % in total weight of one or more elements selected from the group consisting of Cu, Ag, Zn and Sn. Thus, ridging marks is restrained in the aluminum alloy sheet.
