Abstract

The invention relates to an aluminum alloy. The aluminum alloy comprises the following components of, in percentage by mass, 0.01wt%-0.05wt% of Si, 0.08wt%-0.15wt% of Fe, 0.05wt%-0.15wt% of Mn, 1.2wt%-1.7wt% of Mg, 0.02wt%-0.10wt% of Cr, 0.003wt%-0.020-wt% of V, 0.008wt%-0.02wt% of Ti, 0.00005wt%-0.0002wt% of Be, and the balance Al. The invention further provides a preparation method of an aluminum alloy rivet wire for furniture. The preparation method comprises the following steps of, (1) smelting; (2) casting; (3) rolling; (4) drawing comprising non-finished product drawing and finished product drawing and intermediate annealing, wherein during non-finished product drawing, carrying out intermediate annealing once the section compression rate of material changes by 40%-60%, and then carrying out drawing, during finished product drawing, obtaining the aluminum alloy rivet wire for the furniture when the section compression rate of the material is 10%-30%, intermediate annealing comprises the following steps of heating the drawn wire to 150-250 DEG C firstly, keeping the temperature for 4-5 hours, then heating the drawn wire to 350-500 DEG C in the speed of 50-100 DEG C / h, keepingthe temperature for 0.5-1 hour, and then cooling the drawn wire to room temperature.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to an aluminum alloy rivet wire for furniture and a preparation method thereof. Background technique [0002] At present, the connection methods of aluminum alloy furniture include welding and riveting. Among them, pure rivet wire of grade 1050 is widely used as riveting material, which is characterized by low strength (tensile strength 80-120MPa) and high cold heading cracking rate. Therefore, how to use a simple and economical process to solve the problems of high cracking rate and low mechanical strength of rivet wire cold heading is the focus of the industry at present. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide an aluminum alloy rivet wire for furniture and its preparation method. Through the innovation of components and process methods, the present invention can not only solve the problem...
