Abstract Magnesium alloy extrusion mold and the craft parameter were studied.According to magnesium alloy characteristic,the 4 holes extrusion mold was designed.Extrusion experiment was carried out with the MB2 on 1 250 ton extruder.The magnesium stick temperature is at 548~698 K,mold temperature at 530~673 K,extrusion tube temperature at 573~723 K,extrusion speed at 0.067~0.083 m/s,and extrusion ratio at 40~60.Compared to aluminum alloy pipes,magnesium metal alloy pipes have good(mechanics) function and machine function,and satisfiys the sprinkler engineering.pipe;magnesium alloy;extrusion;mold;craft parameter;sprinkler
