Aluminum is a chemical element in the table of elements with atomic number 3 and chemical symbol Al. The density of aluminum is lower than other common metals. It is about one third of the density of steel.
This element has a great desire for oxygen. When exposed to air, it forms a protective oxide layer on its surface.
Aluminum is similar to silver in terms of appearance, high ability, color, and light reflection. This element is non-magnetic and soft and malleable.
Aluminum has a stable isotope 27Al. This isotope is abundant and makes aluminum one of the 12 most common elements in the world.
The melting point is 1220.58F, 660.32C.
Density g/cm3–2.70.
The speed of sound is 5000m/s
Electrical conductivity nΩ.m26.5
The high strength of aluminum and its alloys made aluminum the most widely used among non-ferrous metals in the manufacture of parts. Aluminum parts can be made by sand casting, pressure casting, hot work or cold work and extrusion. Aluminum alloys are capable of machining, pressing, soft soldering, hard soldering and welding.
Special aluminum is melted at a temperature of 660 degrees Celsius, it is very suitable for the production of parts by sand casting or pressure casting.
Corrosion resistance of aluminum alloys depends on the quality of thin oxide coating, which is created on its surface.
Since aluminum is an active metal, this coating is quickly formed on it. Scratching or wearing this coating makes it possible for this metal to corrode. By anodizing method, a thick oxide coating can be created on the surface of aluminum.
This type of gate is among the most widely used type of aluminum cooler gate in Iran. Its multi-purpose structure is made of vertical blades in the front and horizontal blades in the back, which made this product attract the attention of users and employers from the past.
This aluminum cooler gate is made of aluminum profile material and has a damper that controls air pressure regulation or prevents air from entering.
The frame of this gate is made of aluminum profile mold and its blades are made of aluminum sheet in original form. Its final beauty and protective layer is the furnace paint.
The most obvious feature of the aluminum cooler gate is the ability to change the direction of the vertical blades installed in the front of the gate. In fact, by changing the direction of these vanes, the air coming out of the opening will be easily transferred to the left, right or straight and as desired.
In addition to the vertical blades in the front part, and in the back part, horizontal blades are considered as dampers, which are movable blades and have the ability to block the air path. They also have the ability to change the direction of the air from the gate opening.
The horizontal blades of the damper of this aluminum cooler gate are controlled and opened and closed by the lever whose control handle is installed on the face of the gate.
This type of cooler gate can be manufactured and supplied in different dimensions and without size restrictions, as customized and with any number required by the requester. Like the iron sample, the thickness of the horizontal and vertical blades determines the quality or lack of quality of the material of this product. Among other important factors in determining the quality of the aluminum cooler gate is the type and quality of its surface color. Static powder paint is usually used to cover it.
These gates are usually used on the wall, but using them on the roof will not cause any problems in its performance. Self-tapping screws or wood screws are used to install them in the desired location.
The production of this smart and advanced equipment and its installation in the interior of buildings is such that it prevents the transfer and entry of any type of pollution and dust particles inside. The technologies resulting from the construction of these gates indicate that this part of the cooler is strong and has a very high resistance. In such a way that it will act as a strong sound and heating insulator. The chassis rail section in this product allows the user to simply unlock it and access all parts.
