A so-called heat treatment type Al alloy such as a -Si type 6262 alloy is used. However, the heat treatment type Al alloy requires a solution treatment at a high temperature and a subsequent quenching step. These Al alloys cannot improve predetermined performance, that is, machinability and strength, unless subjected to so-called heat treatment.
By the way, these heat treatment type Al alloys have a drawback that non-uniform stress is generated inside the material due to solution treatment and quenching, and it is difficult to obtain sufficient dimensional accuracy during subsequent cutting.
In particular, when extruded tube rod material is cut to a specified length, cold-forged into precision machine parts, and then subjected to solution heat treatment and quenching, residual stress is large and it is difficult to remove the stress, and the dimensional accuracy after cutting is high. There was a drawback that was difficult to obtain.

Compared with JIS5056 alloy, machinability has been improved without compromising performance such as corrosion resistance and peeling resistance of anodized film due to heating, and although the performance is balanced for the time being, in terms of original machinability, In addition, it is difficult to satisfy the recently increasing requirement level. Further, since the conventional JIS5056 alloy and the improved alloy are originally Al-Mg base alloys, the hot extrudability is poor and there is a problem in the extrudability.

不足する。Next, the action of each component in the non-heat treatment type extruded Al alloy pipe rod material for cutting of the present invention and the reason for limitation will be described below. 2-5% of Mg is necessary to give a predetermined strength to the alloy and is a main hardening element component. When Mg exceeds 5%, the extrudability becomes poor. If it is less than 2%, the strength is insufficient. Cu 0.1 to 0.5% acts to improve machinability.
Such addition of Cu not only makes the cutting chips finer, but also makes the cutting surface smooth, but
If it exceeds 5%, the corrosion resistance is deteriorated. If it is less than 0.1%, the above effect is insufficient. Si 0.3 to 1.0% has an effect of significantly improving machinability. When Si exceeds 1.0%, the cutting waste becomes finer, but the cutting surface becomes rough. If it is less than 0.3%, the above effect is insufficient. Zr0.
05-0.2% has the effect of refining crystal grains, improving strength and improving stress corrosion cracking resistance. If Zr exceeds 0.2%, coarse crystallized substances are likely to be formed, which deteriorates machinability.
If it is less than 0.05%, the above effect is insufficient. Pb, Sn
Or Pb, Bi, Sn total content 0.5
~ 2.5% has an effect of improving machinability, and if any of them is less than the lower limit, the improving effect is insufficient, and if it exceeds the upper limit, a coarse compound is formed, and hot extrusion processability and surface processability are obtained. And deteriorates corrosion resistance. Fe 0.1 to 1.0% has an effect of refining crystal grains and improving machinability, but if it exceeds 1.0%, the effect is saturated, and if it is less than 0.1%, the effect is insufficient.

It has an excellent effect that these performances are well balanced. Further, the alloy containing Zn added thereto has the effect of greatly improving the hot extrusion workability in the material manufacturing process. Further, since the Al alloy tube rod material of the present invention is a non-heat treatment type, it is possible to omit the solution treatment and the subsequent quenching step, thereby reducing the cost, and by omitting this step, it is possible to achieve a low residual stress and to reduce the time of cutting. The dimensional accuracy can be greatly improved.
