The pack alloy of anodic oxidation, in addition to containing Al, Si, Fe and Mn, in alloy
In be also added into Mg and Ti, but after adding Mg and Ti in the aluminium alloy of die casting, making
It is standby that into during casting, yields is relatively low, and its as anode in use, can show
Dark red is heterochromatic, influences using effect.In addition, in the special of application number 201510278230.9
Also disclosed that in profit it is a kind of can die casting can anodic oxidation ferro-silicon-aluminium manganese rare earth alloy, except containing
Beyond Al, Si, Fe and Mn, rare earth metal and additive A are also added into the alloy, its
Middle additive A be Co, either Ni or Mg, or Cr, or Co, Ni, Mg,
Cr two of which or three kinds or four kinds of mixtures, not only increased wherein adding rare earth metal
Production cost, while also and do not solve the low technology of the yields during casting is prepared into and ask
Topic, and the addition of additive A equally exists above-mentioned technical problem：It is being prepared into casting
During, yields is relatively low, and its as anode in use, heterochromatic, shadow can be showed
Ring using effect.
The content of the invention

Embodiment
With reference to embodiment, to the present invention can anodic oxidation pack alloy make it is further
Explanation：
In the prior art, the film layer of usual anodic oxidation generation continuous uniform requires that the content of aluminium reaches
More than 95%, for conventional electrolytic aluminium (fine aluminium) because of poor fluidity, elevated temperature strength is weak, is stripped energy
Power not enough and can not die cast, show to add on the basis of electrolytic aluminium through substantial amounts of experiment
Si, Fe carry out melting, and according to Metallographic Analysis, Al is included in material12Si2Fe3Nucleus, Mn is thin
Change crystal grain and form new big skeleton nucleus Al simultaneously6MnFeSi2, test the base shown in electrolytic aluminium
Si, Fe and Mn are only added on plinth, it is possible to reach make alloy have preferable mobility with
The effect of removal, while there is preferable die casting performance, anode oxidation film-forming is more uniform,
Coloring effect is preferable.Wherein, can add in the pack alloy of anodic oxidation in the present invention
Si can improve intensity when mobility, tensile strength, hardness, machinability and high temperature, enhancing
The removal of aluminium alloy；The Fe added, acicular crystal can be formed with other metals, by
It is chilling in die casting, can be advantageous to separate out fine grain, strengthen the mobility of alloy, beneficial to the demoulding,
Improve die casting performance and then improve the quality of casting,；The Mn added, the height of alloy can be improved
Warm intensity, aluminium alloy recrystallization process can be prevented, improve recrystallization temperature, significantly refinement again
Crystal grain, mobile performance is improved, improve die casting performance, prevent from ftractureing, improve casting quality.
