HYPEREUTECTIC ALUMINUM-SILICON CASTING ALLOY |
摘要 |
<p>HYPEREUTECTIC ALUMINUM-SILICON CASTING ALLOY A hypereutectic aluminum-silicon casting alloy having particular use in casting cylinder blocks for marine engines. The alloy is composed by weight of 16% to 19% of silicon, 0.4 to 0.7% magnesium, up to 0.37% copper and the balance aluminum. With the stated silicon content the alloy has good fluidity and the preciptiated silicon crystals provide excellent wear resistance. In addition, the alloy has a narrow solidification range of less than 150.degree.F, thereby providing the alloy with excellent castability. The copper content is maintained at a minimum so that the alloy has improved resistance to salt water corrosion.</p> |
