摘要： PURPOSE: To provide an integrated hollow product of high strength at a low cost by forming a recessed part or a deformed part in an extruded Al alloy hollow stock to make the preliminary shape close to the designed one, and realizing the designed shape by bulging the preliminarily shaped member. CONSTITUTION: An Aluminum alloy hollow product 1 is provided with a flange 10 on the side along the longitudinal direction, and recessed parts 11, 12 and a flat part 13 are locally formed on the corner of the upper part. The prescribed parts of a hollow stock corresponding to the recessed parts 11, 12 and the flat part 13 of the hollow product 1 are pressed by a press jig to be worked as a preliminary shape close to the designed shape of the hollow product 1. Then the hollow stock is placed in a bulging die consisting of an upper die and a lower die, both ends of the hollow stock are covered by a piston rod, the liquid is fed from a high pressure liquid feeding passage, and the liquid is pressurized to manufacture the hollow product 1 of the designed shape. Because the product is of integrated shape, and free from any joined parts, the strength is high, and the joining process is dispensed with, and the hollow product 1 can be manufactured at a low cost.

摘要： PROBLEM TO BE SOLVED: To smoothly deform corner parts and to obtain an Al alloy extruded square pipe for structural use excellent in bulging workability by making the thickness at the inside of the corner parts of the Al alloy square pipe thinner than the thickness of the peripheral part thereof. SOLUTION: The thicknesses 2a, 2b, 2c, 2d of the corner parts 2A, 2B, 2C, 2D of the square pipe 1 are made thinner than the thicknesses 3a, 3b, 3c, 3d of the peripheral parts, i.e., flat parts 3A, 3B, 3C, 3D. In this case, the thickness of the corner part is controlled to 0.5-0.9 of the thickness of the flat part, that is, in the case of 0.9, the difference of the bulging formabilities between the corner part and at the flat part occurs and the corner part is liable to breaking. Further, the radius R2 at the inside corner of the square pipe 1 is preferably controlled to some more than zero and the radius R1 at the outside corner is preferably controlled to >=0.5mm for facilitating the formation of the corner part. All of the four sides 3A, 3B, 3C, 3D are uniformly bulged by the bulging work and the formed product is used as it is, or the bulged part is cut off, then it is used as a joint.

摘要： PURPOSE:To inexpensively produce an Al alloy sheet excellent in formability in the case of using low viscosity lubricating oil by a simple process by subjecting the cold rolled sheet of an Al-Mg alloy having a specified compsn. to process annealing, thereafter subjecting it to final cold rolling by a roll having a specified surface roughness and executing final annealing. CONSTITUTION:The ingot of an Al allay contg., by weight, 2.0 to 8.O% Mg and furthermore contg. one or >=two kinds among =0.8mum. The Al alloy sheet having high formability under low viscosity lubrication only by ordinary roll finishing can be produced at a low cost without subjecting the surface of the Al alloy sheet to special shot dull finishing.
