Description
Technical field
The present invention relates to the technical fields of aluminum alloy material, more particularly to a kind of compound high tenacity, corrosion resistant aluminium
Alloy material and preparation method thereof.
Background technique
According to statistics, metallic aluminium is the highest metal of content in the earth's crust, so the application of aluminium material embodies in daily life
Every aspect, widely applied in aerospace, automobile, machine-building, ship, chemical industry and daily necessities.But
Be metallic aluminium be not in the form of metal simple-substance apply, substantially used in the form of aluminium alloy, since its purposes is wide
General, so the alloy formula of each aluminium alloy manufacturer is different, and aluminium alloy is common issue is that poor toughness and not
It is corrosion-resistant.
Therefore, the invention patent inventor, for aluminium alloy poor toughness and not corrosion-resistant situation, it is intended to invent a kind of new
High tenacity, corrosion resistant aluminum alloy material and preparation method thereof, it is desirable to can use other less metals, obtain optimal
Aluminium alloy that is corrosion-resistant and improving toughness.
Summary of the invention
To overcome disadvantages mentioned above, the purpose of the present invention is to provide a kind of high tenacity, corrosion resistant aluminum alloy material and its
Preparation method.
In order to reach the goals above, the technical solution adopted by the present invention is that: a kind of high tenacity, corrosion resistant aluminum alloy material
Matter is made of following element: silicon, iron, copper, manganese, magnesium, zinc, titanium and aluminium.
Preferably, the mass percent of the element of each component: silicon 6.5-7.5%；Iron 0-0.08；Copper 0-0.05；Manganese
0-0.03；Magnesium 0.3-0.6；Zinc 0-0.03；Titanium 0-0.2；Remaining is aluminium.
Preferably, the mass percent of the magnesium is 0.5-0.6.The content for improving magnesium helps to improve aluminium alloy entirety
Hardness.
Preferably, a kind of high tenacity, the preparation method of corrosion resistant aluminum alloy material,
S1, aluminium ingot is carried out it is electrolyzing fused, make aluminium ingot present molten state；
Silicon, iron, copper, manganese, zinc and titanium are put into the aluminium of molten state according to its corresponding mass percent, and carried out by S2
It is sufficiently mixed；
The magnesium of corrresponding quality is added again, is thoroughly mixed by S3；
S4 pours into mixed metal liquid made from previous step in mold, finished product of casting.
Preferably, mixed metal liquid obtained should be within 4 hours using finishing in the S3 step.
A kind of high tenacity of the present invention, the beneficial effect of corrosion resistant aluminum alloy material are that the aluminium that thus ratio is produced closes
Gold has high tenacity and highly corrosion resistant, while its hardness also improves, and be formulated it is scientific, at low cost, with splendid casting
The property made.
A kind of high tenacity of the present invention, the beneficial effect of the preparation method of corrosion resistant aluminum alloy material are, molten by being electrolysed
Molten aluminum ingot and assistant metal, are uniformly mixed it quickly, are eventually adding magnesium, improve the corrosion resistance of aluminum alloy material, toughness and
Metal liquid is poured into corresponding mold by four steps, corresponding metal product can be obtained by intensity, and method is simple,
Full-automatic production is easily carried out in conjunction with automation control program, more meets the demand of modern industrial production.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
In middle school chemistry, we just have appreciated that the chemical property of aluminium is also more active than iron, and ironwork it is frequent because
For get rusty without can permanent use, but since the oxygen in aluminium and air can generate aluminum oxide in reaction, and three oxygen
Change that two aluminium itself are finer and close and compact, so fine and close protective film can be formed on the surface of aluminium, prevent air and aluminium into one
Step reaction, but the protective effect of this protective film is limited after all, is also needed other methods in the industrial production and is gone
Realize corrosion resistant function.The toughness and hardness of aluminium material itself are also relatively low, so the invention patent invention human desires mentions
For a kind of high tenacity, corrosion resistant aluminum alloy material and preparation method thereof.
One of the present embodiment high tenacity, corrosion resistant aluminum alloy material and preparation method thereof, wherein high tenacity, corrosion resistant
The aluminum alloy material of erosion is made of following element: silicon, iron, copper, manganese, magnesium, zinc, titanium and aluminium.The quality percentage of the element of each component
Than: silicon 6.5-7.5%；Iron 0-0.08；Copper 0-0.05；Manganese 0-0.03；Magnesium 0.3-0.6；Zinc 0-0.03；Titanium 0-0.2；Remaining is
Aluminium.Especially the mass percent of magnesium is 0.5-0.6.The content for improving magnesium helps to improve the hardness of aluminium alloy entirety.
A kind of high tenacity, the preparation method of corrosion resistant aluminum alloy material,
S1, aluminium ingot is carried out it is electrolyzing fused, make aluminium ingot present molten state；
Silicon, iron, copper, manganese, zinc and titanium are put into the aluminium of molten state according to its corresponding mass percent, and carried out by S2
It is sufficiently mixed；
The magnesium of corrresponding quality is added again, is thoroughly mixed by S3；
S4 pours into mixed metal liquid made from previous step in mold, finished product of casting.
Wherein it is especially noted that mixed metal liquid obtained should be within 4 hours using finishing in S3 step.
If shelved for a long time, the content and activity of magnesium metal will lead to, pay attention to shelving for a long time, will lead to the oxygen in air
Reacted with the active metal in mixed metal liquid, and the activity of the metal in mixed metal liquid from greatly to it is small successively
It is
Magnesium > aluminium > titanium > manganese > zinc > iron > copper
It follows that it is significant to note that the oxidation of magnesium, the activity of aluminium be it is deputy, in aluminium not by complete oxygen
Before change, it is that no enough oxygen removes the metal reaction for being lower than aluminium with activity, is completed so being prepared in metal mixed liquid
Afterwards, it timely uses and finishes, otherwise can make magnesia therein, and then influence the content of magnesium in aluminium alloy entirety, reduce aluminium conjunction
The activity of gold.
High tenacity, the beneficial effect of corrosion resistant aluminum alloy material are the aluminium alloys that thus ratio is produced, and have high-ductility
Property and highly corrosion resistant, while its hardness also improves, and be formulated it is scientific, at low cost, with splendid castability.
High tenacity, the beneficial effect of the preparation method of corrosion resistant aluminum alloy material be, by electrolyzing fused aluminium ingot and auxiliary
Aided metal is uniformly mixed it quickly, is eventually adding magnesium, improves the corrosion resistance, toughness and intensity of aluminum alloy material, passes through
Four steps pours into metal liquid in corresponding mold, and corresponding metal product can be obtained, and method is simple, easily combines automation
Control program carry out full-automatic production, more meet the demand of modern industrial production.
The technical concepts and features of embodiment of above only to illustrate the invention, its object is to allow be familiar with technique
People understands the contents of the present invention and is implemented, and it is not intended to limit the scope of the present invention, all spiritual according to the present invention
The equivalent change or modification that essence is done, should be covered by the scope of protection of the present invention.
