Abstract
The present invention relates to corrosion-resistant high-strength weldable aluminum alloy with good extrudability. In aluminum alloy containing Zn, Mg, Cr, Mn and Sb, 0.05 to 0.6% (weight) of rare earth elements are added, and the content of impurities (Fe, Si and Cu) is controlled. The constituent ratio (weight percentage) of each element is 2 to 6 of Zn, 0.8 to 2.5% of Mg, 0.1 to 0.3% of Cr, 0.05 to 0.8% of Mn and 0.05 to 0.3 of Sb, and the rest is aluminum. The aluminum alloy of the present invention has good extrusion performance, good corrosion-resistance and good heat tinting performance. The present invention is suitable for a plurality of welding members, high-intensity structural members, stress members of vehicles, etc.
Description
The present invention is a kind of aluminium alloy.This alloy contains Zn, Mg, Cr, Mn, Sb adds thulium, is applicable to that important component, weldment, replacements such as the structure stress spare of bike, motorcycle, building doors and windows, various communications and transportation and aviation, aerospace do not repair steel etc.
The aldural of Shi Yonging mainly is that Al-Cu is an alloy in the past, and Al-Mg is an alloy, and Al-Zn-Mg-Cu is an alloy, and Al-Mg-Si is an alloy.Though Al-Cu, Al-Mg are alloy advantages of higher tensile strength is arranged, Al-Mg is that solidity to corrosion, the weldability of alloy is also fine, and its extruding property is bad, is difficult to produce in enormous quantities.LC4-LC6, Al-Zn-Mg-Cu series high-strength aluminum alloy (7075 alloys such as grade of the U.S.), though its intensity is high, extruding property is also bad, temperature control strictness during extruding, otherwise be prone to thermal crack, or squeeze is excessive, disadvantages such as extrusion mould life-span weak point.Al-Mg-Si is an alloy, when Mg amount and Si amount are adjusted to maximum, though also can obtain higher-strength and good extrusion performance is arranged, owing to Mg
2The volume of Si phase is separated out, and causes the grain boundary crackle, and alloy material ductility is descended significantly, and be difficult to practical application.The spy opens clear 60-82643, and the alloy that special public clear 56-2148 provides removes the alloying element composition, and outside ratio was not quite similar, its performance can not show a candle to alloy of the present invention.
According to the deficiency of now using aluminium alloy capability, the present invention proposes a kind of aluminium alloy of new composition, and it has good extrusion performance and comprehensive mechanical property, and welding property, corrosion resisting property and surface treatment properties are also very superior simultaneously.
Aluminium alloy provided by the present invention, be a kind of Zn of containing, Mg, Cr, Mn, Sb, aluminium alloy, its difference is under the condition of following ingredients weight percent, and adding content is 0.05～0.6%(weight) rare earth element, the content of controlling impurity F e, Si, Cu simultaneously within the specific limits:
Zn：2.0～6.0% Mg：0.8～2.5%
Cr：0.1～0.3% Mn：0.05～0.8%
Sb：0.05～0.3%
The RE(rare earth) 0.05～0.6%
All the other are aluminium for foreign matter content: Fe≤0.4% Si≤0.4% Cu≤0.2%.
Aluminium alloy of the present invention has good extruding, rolling processing performance and excellent corrosion resistant performance.It can be adapted to welding, electric-arc welding, and weldments such as argon arc welding, and be widely used as high-strength structure spare for building, the stressed member of the vehicles such as automobile, motorcycle, bike, structural part; Important structure parts such as steamer, aircraft, aerospace replace stainless steel.Also have fabulous heat-tinting performance simultaneously, obtain very beautiful appearance, and can in light industrial goods, be widely used.
Embodiment of the present invention can adopt embodiment listed in the table to realize.Adopt aluminium alloy of the present invention and five kinds relatively alloys (seeing Table) do the contrast experiment, its performance is listed (see Table two, table three) melting respectively and casting technique all adopts ordinary method.
