ALUMINUM ALLOY EXTRUDED MATERIALS,FERRULE MADE BY ALUMINUM ALLOY EXTRUDED MATERIALS AND METHOD FOR MANUFACTURING ALUMINUM ALLOY EXTRUDED MATERIALS

摘要

In order to solve this problem, the present invention is in common aluminum alloy lasso to the present invention. It is designed to provide with excellent aluminium alloy lasso integrated intensity and ductility and its manufacturing method, by carrying out work hardening and precipitation-hardening in thermomechanical treatment process maximization machinery row Al-Mg and Al-Mg-Si alloy. The manufacturing method of aluminium alloy lasso, comprising: molten alloy is generated in step (1), by 1.5-3.Mg, Al and inevitable impurity of 0 weight % generate molten alloy, by 0.3-1.The magnesium of 0 weight %, less than 0.2-. 1.Si, Al and inevitable impurity of 0 weight %; Step (2) keeps the temperature 650-750 degree of molten aluminum, and produces blank and pass through casting process; Step c is homogenized and the blank of heat treatment production is in temperature 300-550 degree 0.2 hours heat treatment blanks of 5-96 simultaneously use water; Billet is squeezed out in temperature 200-550 degree for preheated charge with Step d. The lasso that yield strength generates is greater than 50 MPa, and tensile strength is greater than 150 MPa, is 25% or more with elongation strain. ;The 2014 of copyright KIPO submissions
