れている。Normally, 99.5% to 99.8% pure aluminum is used as a material for impact extruded aluminum tubes, but the problem is that the tubes after being phosphorized are contaminated with impurities, especially oxides. Even if you are not doing so,
There is a need to improve this problem because it occasionally breaks and leaks the contents if it is frequently bent during use. In addition, with the recent rise in energy costs, it is expected to provide materials that can be hammered at low temperatures and in a short time by easing the false anchor conditions.

出し本発明を完成するに至った。The inventors of the present invention have conducted intensive research to solve the above problems, and have found that an aluminum-based alloy, which is made by adding cobalt and nickel as essential components to aluminum, has excellent ductility by performing phosphorous dulling treatment after impact extrusion processing. At the same time, the phosphorus annealing treatment conditions were lowered to lower temperatures and shorter times, and the scales were observed.
This led to the completion of the present invention.

) and 0.05 to 3% by weight of nickel (Ni) as essential components, and the total content of CO+Ni is at least 0.15% by weight, with the balance consisting of aluminum and inevitable impurities. The present invention provides an aluminum alloy for use in aluminum alloys.
以下本発明をさらに詳細に説明する。The present invention will be explained in more detail below.

．１５重量％以上である。The aluminum alloy for impact extrusion of the present invention contains 0.05 to 3% by weight of cobalt and 0.05 to 3% by weight of nickel as essential components, and the total content of Co and Ni is 0.

きる。In the aluminum alloy of the present invention, it is essential to simultaneously add cobalt and nickel as alloy components. In comparison, the ductility after competitive annealing treatment is significantly improved, and the recrystallization temperature is lowered, making it possible to relax the soot annealing treatment conditions.

使用すれば本発明の効果、目的は十分に達成される。However, the total content of Co+Nj is 0.15% by weight
If it is less than that, the desired improvement in properties will not be achieved. Furthermore, even if the amount of cobalt or nickel added is excessive, it is not expected to improve the properties commensurate with the amount added, and the material cost of the alloy will increase unnecessarily. The preferred range of alloy components varies depending on the intended use and conditions of use, but those with a particularly remarkable effect of improving ductility include 0.2 to 2% cobalt and 0.2% by weight of cobalt. An aluminum alloy consisting of ~2% by weight of nickel and a total content of Co+Ni of 3% by weight or less is suitable. There are no particular restrictions on the purity of the base aluminum, but the effects and objects of the present invention can be fully achieved if commercially available pure aluminum of 99.5% or more is used.

件は緩和される。As a manufacturing method for the impact extrusion tube, a commonly used impact extrusion process, so-called impact process, is directly adopted. That is, the aluminum alloy slag of the present invention, which has the shape of the intended product, is impact extruded and then softened by cold processing. It is an essential requirement for the aluminum alloy slag of the present invention to be subjected to a softening process after impact extrusion in order to exhibit the characteristics of the alloy of the present invention. Accordingly, the processing conditions are relaxed.
