力４つた。Conventionally, hypereutectic aluminum-silicon alloys have been used as aluminum alloys for internal combustion engine cylinders, but these alloys lack sufficient strength, compatibility with piston rings, and machinability, and lack silicon. It has the disadvantage of causing galling, and for this reason, it is difficult to use it as a cylinder for internal combustion engines, etc. if it is processed by normal cutting and honing.

害のおそれがある婢の欠点があった。In addition, a hypereutectic aluminum-silicon alloy in which 2 to 3096 lead is precipitated was proposed as a wear-resistant aluminum alloy suitable for internal combustion engine cylinders (%Koaki, 1-+, U publication). However, there are manufacturing technical difficulties in uniformly dispersing and precipitating lead during casting of this alloy, and there is also a drawback that there is a risk of lead pollution in the manufacturing process.

％の範囲内で含有させる。To explain the effects of each component in the alloy of the present invention, silicon has the effect of reducing the thermal expansion of the alloy and improving the wear resistance overall. If the silicon-containing thread is less than /'AO 9, it will not be able to fully exhibit the above effects, and if it is cured to a silicon content exceeding 20.0, the castability will deteriorate.
Since the machinability becomes worse, /≠θ~20. Contain within the range of OM liquid %.

．． If the ratio is less than 0 times 9, the above effects cannot be fully exhibited. In addition, when the content exceeds θ weight total 9, the amount of CuA 12 produced will be lower than CuA in α-AI.
I! The amount of solid solution becomes larger than the maximum amount of solid solution, and the fluidity of the molten metal deteriorates, resulting in poor castability. For this purpose, the content of copper is 2.0 to 0.

れていたが、７．０重蓋九以上を添加した例を見ない。Iron has the effect of improving the initial scuffing properties of the alloy. In general, one of the easy characteristics that determines the quality of internal combustion engine cylinders using this type of alloy is the initial scuffing property. By containing it within the range of 96, its initial scuff resistance,
The congability was significantly improved. Conventionally, iron was added to this type of alloy for the purpose of improving the fluidity of the molten metal and improving the sticking property to molds, etc. within the range of /, θ weight 9 or less, but iron was added within the range of 7.0 weight 9 or more. I have not seen any examples of adding .

きものである。However, by adding iron in an amount of /, J' to lAθ, the scuffing resistance, especially the initial scuffing resistance, was significantly improved, and this was discovered for the first time in the present invention. That is, the present invention uses iron as A! The biggest feature is that it adds up to 4 tons and 0 weights. Note that if the iron content exceeds 9 lAO weight, casting problems such as an increase in the temperature of the molten metal will occur, so the iron content should be kept at a maximum of lAO weight tX.
