Abstract
The invention discloses an improved 2024 aluminum alloy. The aluminum alloy is composed of the following components by weight: 3.8-4.9% of Cu, 1.2-1.8% of Mg, 0.3-0.9% of Mn, 0.5% of Si, 0.5% of Fe, 0.25% of Zn, 0.1% of Cr, 0.15% of Ti, 0.01-0.03% of In and the balance of Al and inevitable impurities, wherein the weight ratio of Mn to Mg is 1: (0.4-0.42). Compared with the existing 2024 aluminum alloys, the improved aluminum alloy provided by the invention has better comprehensive properties.
Description
Technical field
The present invention relates to a kind of 2024 aluminium alloys of improvement.
Background technology
2024 aluminium alloys are that in duralumin, consumption is maximum, have the advantages that intensity is high and heat-resisting, can be used as the working part of less than 150 DEG C, when temperature is higher than 125 DEG C, the also height of strength ratio 7075 aluminium alloy of 2024 aluminium alloys, is widely used in aircraft structure (covering, skeleton, girt strip, bulkhead etc.), rivet, hardware, truck hub, propeller element and other various structural parts.
Summary of the invention
The object of this invention is to provide a kind of 2024 aluminium alloys of improvement.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
2024 aluminium alloys of improvement, by weight, are made up of following component:
Cu 3.8-4.9%, Mg 1.2-1.8%, Mn 0.3-0.9%, Si 0.5%, Fe 0.5%, Zn 0.25%, Cr 0.1%, Ti 0.15%, In 0.01-0.03%, surplus is aluminium and inevitable impurity, and wherein, the weight ratio of Mn and Mg is 1:(0.4-0.42).
Compared with existing 2024 aluminium alloys, tensile strength and the yield strength of the aluminium alloy after the present invention improves can improve about 10-15%, and unit elongation can improve 15-20%, and over-all properties is significantly improved.
