Description of the Related Art Conventionally, iron-based materials have been used for parts that are subject to strong wear among compressor parts of air conditioners such as room air conditioners and car air conditioners. However, recently, aluminum alloys have been used more and more in compressor parts of car air conditioners, for the purpose of weight reduction. As this aluminum alloy for compressor parts, an Al-Si alloy (for example, JISAC4C alloy) is conventionally used, in which Si is added to Al to improve wear resistance, and Cu or Mg is further added to improve strength. Castings were used. However, recently, in car air conditioners, due to CFC gas regulations, compressor parts with more excellent strength and wear resistance have been required, and it is necessary to change from cast products to forged products even as compressor parts made of aluminum alloy.

生じるという問題がある。Recently, however, one-sided swash plate type compressors have been increasing as compressors, and pistons and rod plates in these compressors are finally connected to a connecting rod by caulking. Therefore, it is required that the material of the piston and the rod plate has an elongation that allows caulking. However, in the above-mentioned Al-Si alloy used conventionally, elongation is insufficient when the strength is increased by heat treatment such as quenching and tempering, and cracking occurs during caulking. In addition, it is annealed to soften it,
When the elongation is increased, crimping is possible, but strength and abrasion resistance are insufficient, and there is a problem that the crimped portion is loosened during use.

表２にこれらの結果を示す。EXAMPLES The present invention will now be described in more detail with reference to examples. (Example 1) An aluminum alloy having an alloy composition shown in Table 1 was cast into a 219 mmφ ingot by water cooling, and 470
After carrying out a homogenizing treatment at 12 ° C. for 12 hours, it was reheated to 450 ° C. and hot extruded to obtain a 30 mmφ bar. After the annealing treatment of this bar material and the solution treatment and quenching treatment,
An artificial aging-treated T6 material was obtained and used as a sample. The heat treatment conditions were standard conditions. The T6 material was subjected to a tensile test to measure the tensile strength, proof stress and elongation, and the specific wear amount was determined with an Ogoshi-type wear tester to evaluate the wear resistance. As for the evaluation standard of wear resistance, the relative amount of wear obtained by dry and wet by the Ogoshi-type wear resistance test was evaluated by relative comparison between materials. Regarding the O material, the cold forgeability was evaluated from the working limit in the upsetting test, and the crimpability was evaluated from the easiness of cracking by caulking the piston-shaped one with a ball. The evaluation criteria of the cold forgeability were that those that were capable of being machined by 60% or more were good, and those that were less than 60% were bad, with the processing limit by the upsetting ratio as an index. In addition, the crimpability was evaluated by inserting a steel ball into the piston, subjecting it to crimping, and then evaluating the crackability.
Table 2 shows these results.
