Description
Technical field
The present invention relates to metal alloy compositions field, particularly relate to a kind of aluminium alloy.
Background technology
Aluminium is element distributed more widely, and in the earth's crust, content is only second to oxygen and silicon, is that in metal, content is the highest.Fine aluminium density is lower, is 2.7 g/cm3, has good heat conduction, electroconductibility (being only second to Au, Ag, Cu), and ductility is good, plasticity is high, can carry out various mechanical workout.The chemical property of aluminium is active, and in air, rapidly oxidation forms that one deck is fine and close, oxide film firmly, thereby has good solidity to corrosion.But the intensity of fine aluminium is low, only have the various aluminium alloys that just can obtain doing structure materials'use by alloying.
Aluminium alloy is to take the alloy general name that aluminium is base.Main alloy element has copper, silicon, magnesium, zinc, manganese, and less important alloying element has nickel, iron, titanium, chromium, lithium etc.Aluminium alloy density is low, but strength ratio is higher, approaches or surpasses high-quality steel, and plasticity is good, can be processed into various section bars.Especially aluminium alloy replaces steel casting can alleviate structural weight, so the requirement good and lightweight aluminium alloy of exploitation over-all properties increases day by day.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of aluminium alloy, there is good electroconductibility and thermal conductivity, and erosion resistance, and intensity is high, quality is light, can replace steel to be used for the aspects such as machinofacture, Transport Machinery, power machine and aircraft industry, alleviate structural weight and reach more than 50%.
