First of all, what is the aluminum alloy profile? It is probably that the aluminum profile is the profile with different sections formed by extrusion of aluminum bar through the die. So what properties does it have? It can be seen from aluminum that it has many excellent properties of aluminum, such as light weight, easy plasticity, strong hardness, etc.

Aluminum can contact with air to form a dense oxide protective film. This protective film is also called aluminum rust. Would you think of rust? That won't make the product more susceptible to corrosion. Then you may be wrong. This layer of aluminum rust will adhere to the aluminum surface so that the aluminum will not be oxidized and corroded. Moreover, we can also process the surface of the aluminum profile to form a protective film, which will make the aluminum profile more resistant to oxidation and corrosion, increase its service life and make it more beautiful.

You might say aluminum is so good, but it's more expensive than iron. There is no way. Aluminum production is more complex than iron at present, and the production cost is larger than iron. But it is just because aluminum is easy to use that it can be mass produced and widely used, so it is normal. I believe that when the production process is mature, the estimated price will be lower, after all, aluminum is the earth's aluminum element content higher than iron.

In this way, it is connected and welded. Generally, aluminum profiles are connected with modular supporting aluminum profile accessories, which are firm and durable. It can be welded, the cost of welding is large, and the oxidized profile is not easy to be welded. When using the welding connection method, aluminum profile material should be used, that is, the profile without surface treatment.

With so much knowledge of aluminum profiles, do you know what they are used in? In fact, many such as frame fence, aluminum radiator, door and window decoration, rail transit, etc.

The above is a little knowledge about aluminum alloy profiles.
