The beneficial effects of the invention are as follows：A kind of aluminium wire, in the state of ensureing that aluminium wire other performances are still good, by adding
Plus the trace element such as silicon, iron, copper improves the corrosion resistance and service life of aluminium；The performance of aluminium is improved, makes obtained aluminium
Silk is greatly improved in wet environment compared to existing aluminium wire antiseptic power, and in the environment that humidity is 70%, prior art is prevented
The rotten life-span, the present invention can reach more than 8 years at 4 years or so, and in water environment, prior art anti-corrosion life was 3 years or so, this hair
It is bright to reach more than 6 years.In the present invention, the ratio of each chemical constituent is just determined by long-term research and strict experiment
Its feasibility, the ratio of each chemical constituent not only affects performance, antiseptic power and the service life of final aluminium wire, and
The ratio of each chemical constituent female shank diameter of chemical combination, content equilibrium degree and last aluminium wire, fineness in fusion process have
Influence, is the aluminium wire for obtaining using the anti-corrosion time limit higher, there is provided indispensable guarantee.
The intensity of alloy is improve by adding iron, silicon, copper, smelt surface tension is reduced, fluidity of molten is increased,
Improve the proof stress of alloy, corrosion to split, improve mechanical property and the plastic working of alloy.It is solid by adding copper to enhance
Molten reinforcing effect；Add silicon to improve the castability and corrosion stability of alloy, with copper, iron molten condition under counteract impurity to alloy
The adverse effect of corrosion stability, it is ensured that alloy is not cracked, reduces alloy fragility；And the addition of iron, carried with copper, silicon collective effect
