In this paper, the liquid extrusion technology had been introduced, and the effect of liquid extrusion on the properties and metallographs of ZnAl13Cu2 alloy had been mainly approached. Through liquid extrusion, the properties and wear resistance of the alloy had been improved a lot, the metalloyraphs were obviously fibriform, and the fractographs were changed into toughness from brittleness. All of these illustrated that the liquid extrusion technology were to be a very useful for practical production.
