   2, gray color, sex can be a hard knock-off;
   3, Al-Si alloy fracture slightly blue-gray color, percussion easily broken, cross-sectional structure was coarse grains, such as mechanical parts and civilian health aluminum.
   4, aluminum-copper alloy of special hardware, good toughness compared with aluminum-silicon alloy. Fracture color white, the section was fine granular or fine organization, such as the cylinder piston, impact resistance, high temperature and high corrosion resistance of the parts.
