Does aluminum alloy rust need to be treated?

Aluminum alloys are selected as raw materials for industrial supplies, ranging from various mechanical equipment to small internal parts. Why are aluminum alloys frequently used by factories? Some customers answered: Because the aluminum alloy will not rust! It will only turn black, but it will not affect its performance.

So is aluminum alloy really rusty? In fact, aluminum alloy is easier to rust than iron. When the surface becomes black, it is the performance of aluminum alloy rust. Does aluminum alloy rust need to be treated?

The way aluminum alloys rust is different from other metals. For example, after iron rust, the generated rust is loose, covering the surface of the iron, and oxygen can continue to oxidize the iron in the layer through the rust until the entire piece is rusted. After the aluminum alloy rusts, the black substance formed is aluminum oxide, which is a layer of dense substance, which will be tightly attached to the surface of the aluminum alloy metal to prevent the aluminum from continuing to react with oxygen and protect the aluminum products from oxide film. Layer effect. Therefore, the aluminum alloy rust does not need to be treated, and the aluminum alloy will automatically generate a protective film.

If you want to use the aluminum alloy to maintain a bright and bright luster, you can choose the aluminum alloy material after oxidation treatment and electroplating treatment. Jiangyin Mingding Aluminum Products Co., Ltd. can provide you with various types and materials of aluminum products, if necessary, can also provide aluminum products processing services.

The more fan blades, the better?

When using industrial fans, people often wonder why some fan blades are 3 and some fan blades are 5. The difference in the number of blades has any impact on the performance of industrial fans. Today, Suzhou Santian Precision Mould Co., Ltd. is here to reveal the answer to this question for you.

The difference in the number of fan blades will indeed affect the working effect of industrial fans.

When the three-blade fan is working, the wind generated is greater than that of the five-blade fan. This is because the larger the number of blades, the greater the load, and the more difficult the fan is when rotating. For industrial fans, it is recommended to choose a three-blade fan.

However, the larger the number of blades, the smaller the piece of wind that can be produced, the softer the wind, and the less noise it emits. This is the reason for the large number of blades for silent cooling fans.

In summary, if you want to choose a fan with a large air volume, you can choose a three-blade fan, but if you want to choose a fan with low noise, you can choose a fan with five or more blades. However, it is not recommended to choose a fan with an even number of blades, such as a fan with 4, 6, or 8 blades, because the even-numbered blades easily lose their balance during rotation, causing the fan blades to collide and cause damage.

How to deal with rusty aluminum tubes

Metals are not properly stored and exposed to the air. They are particularly susceptible to oxidation, which is what we often call rust. Iron rust will produce red rust, and aluminum rust will produce black alumina, so usually we see that the surface of the aluminum tube is dark, that is, the aluminum tube is rusted.

After the aluminum tube is rusted, is there any way to restore him to its original bright luster? In industry, chemical derusting is usually used, which uses the properties of aluminum metal and reacts with chemical substances to remove rust.

Pickling and rust removal: Before pickling and rust removal, the rusty aluminum pipe needs to be degreased. If the oil is not removed, the embroidery will not be washed, and the derusting process takes a long time and the efficiency is low. Pickling the rusty aluminum tube after degreasing, the aluminum tube after pickling shows that it will show a semi-bright state, you can directly perform oxidation treatment. The pickling and derusting operation is simple, and the substrate loss is relatively small.

Alkaline solution rust removal: The lye solution rust removal and pickling rust removal have the same principle, except that the acid solution is replaced with an alkaline solution. However, in the process of derusting, the alkaline solution derusting not only needs to degrease the aluminum tube, but also remove the oxide film of the rusty aluminum tube. One more step than pickling to remove rust.

Both rust removal methods will cause loss to rusty aluminum tubes. Therefore, when buying aluminum tubes, it is best to choose aluminum tubes for electroplating, which can prevent the aluminum tubes from rusting. The aluminum appliances used in our daily life do not need to be derusted even if they are rusted. On the contrary, the aluminum oxide generated by aluminum rust can also protect the internal aluminum tube from oxidation, forming a protective film.

What is the difference between metal blades and plastic blades？

The blade is an important part of the fan, and the functionality of the fan made of blades of different materials is also different. Many consumers want to know what is the difference between metal blades and plastic blades? Today, Suzhou Santian Precision Mould Manufacturing Co., Ltd. is here to answer this question for you.

Under the same quality, metal blades can produce more than plastic blades; the same volume of metal blade tails can shape winglets, which in aerodynamics can help provide better air volume; good power production The air volume of the metal blade is greater than that of the plastic blade; the metal blade is more stable and powerful than the wind produced by the plastic blade.

Seeing this, do you think metal blades are better than plastic blades? However, metal blades are easily oxidized by air, especially when used in a humid environment, metal blades are prone to rust. Once the metal blade is rusted, it is difficult to repair. Even if the rust on the surface of the metal blade can be cleaned in time, the blade will become thinner and thinner and eventually scrapped. The plastic blades can be used in a variety of harsh environments. The high-heat-resistant plastics developed now can even allow plastic blade fans to continue to work at high temperatures without damage.

Metal blades and plastic blades have their own advantages. Consumers should choose according to the actual use site, and the best is the best.

Reasons for the massive use of aluminum in automobile manufacturing

Driving a light and fast car has become the idea of many consumers. Automobile lightweighting is also the goal pursued by the major automobile manufacturing industries today. Under the premise of ensuring the strength and safety performance of the automobile, the weight of the entire automobile is reduced as low as possible, thereby improving the dynamics of the automobile, reducing fuel consumption, and reducing exhaust pollution. After continuous exploration by car manufacturing experts, we finally found a high-quality material for making light and light cars-aluminum.

This is why in recent years, many automobile manufacturers (such as BMW, Mercedes-Benz, Tras, etc.) have begun to use aluminum metal in automobile production. Because the weight of aluminum is much lighter than steel and iron, and aluminum can be made into aluminum alloy with other metal materials, its hardness can also be comparable to steel, so there is no need to worry about the safety performance of cars made of aluminum.

For the use of aluminum metal in the automobile manufacturing industry, it is currently mainly used in four aspects: car body, wheel hub, engine and air conditioning in the car.

The main body of the car body is 2000 series, 5000 series and 6000 series aluminum alloy, and some car manufacturers use 7 series aluminum alloy (usually used in aircraft landing gear or high strength parts of fighter fuselage).

The wheel hub is mainly made of ALSi series alloy, Mg alloy, 6061 deformed aluminum alloy.

The engine is the core of the car, and its cylinder block uses die-cast aluminum alloy. At present, the engine block of some cars cannot be replaced with cast aluminum, and cast iron is still used.

The vehicle air conditioner is changed to an automobile aluminum heat exchanger, which is composed of an aluminum tube that passes cooling water and an aluminum fin that functions as a heat sink.

Please do not prejudice aluminum cars, think that aluminum cars are not safe, because lightweight cars made of aluminum alloys are the future development trend of the entire automotive industry and car users.
