High Quality CNC Milling Machine 5 Axis Aluminum Amplifier Front Panel For Other Audio & Video Equipment

Audio and Video system integration

Often referred to simply as "AVSI", the term is used to describe an engineering contractor or project engaged in audio and video system integration, which is a sub-system of weak current system integration, including sound amplification system, digital conference system, remote video conference system, display system, song demand system, intelligent centralized control system, and lighting system. It is very professional, involving electroacoustics, construction acoustics, psychology, and other edge application science. It is an engineering service content that combines a series of functional systems in audio and video and is often used to describe the engineers or projects that integrate audio and video systems.

Application of aluminum

Aluminum is the most abundant metal in the earth's crust, and its main characteristics are low hardness, corrosion resistance, and lightweight. Aluminum is widely used in production and life.

1. Made of aluminum alloy, aluminum itself is a relatively soft metal, but after adding some alloy components, it will become a hard metal. This light and hard metal, which is also very corrosion-resistant, has been widely used in various fields at once. Such as aircraft, automobiles, ships, rail transit, and other manufacturing industries. In addition, aluminum and aluminum alloys are also widely used in aerospace equipment because of their lightweight. For example, our aluminum profile is also made of aluminum alloy through die extrusion. The aluminum profile is used for various structural parts, equipment accessories, etc.

2. The ductility of aluminum is very good, second only to gold and silver. Aluminum can be pressed into 0.01mm aluminum foil, aluminum wire, aluminum strip, etc. In recent years, aluminum alloy calendars are used for the body of all popular aluminum cars.

3. The higher the purity of aluminum, the better the reflection performance of light. Therefore, the aluminum plate is often used to make high-quality mirrors. In addition, the 500-meter aperture reflecting the sphere of fast500, the world's largest radio telescope made in China, is made of pieces of aluminum plates.

4. The ceiling of the building is made of aluminum, which has sound absorption performance. The broadcasting room and the interior of large buildings all use aluminum ceilings.

5. It can be used to make wires and cables. Although the conductivity of aluminum is weaker than that of copper, its weight is only 1/3 of that of copper, and the weight of aluminum wire is only half of that of copper to transmit the same amount of electricity. In addition to corrosion resistance, the oxide film of aluminum has a certain degree of insulation. It is widely used in the electrical appliance manufacturing industry, wire and cable industry, and radio industry.

6. Aluminum has three times the thermal conductivity of iron and can be used to make all kinds of exchangers, heat dissipation materials, cookers, etc. Like the aluminum alloy radiator we often make, it is also an extruded aluminum profile.

7. Due to their strong corrosion resistance, aluminum, and aluminum alloys are often used in chemical reactors, medical devices, oil refining devices, oil and gas pipelines, etc.

8. Aluminum powder can be used as a coating. The powder of other metals is black, while aluminum powder is silver white. As a coating, iron products can be protected from corrosion and are more beautiful. The aluminum powder will emit a lot of light and heat when burned in oxygen, which can be used to make an explosion mixture, combustion mixture, lighting mixture, etc. Aluminum powder is mixed with graphite and titanium dioxide in proportion, coated on metal, and calcined at high temperature to make high-temperature resistant cermet, which is used in rockets and missiles.

9. Aluminum agents can be used to smelt refractory metals and weld steel rails, and can also be used as deoxidizers in steelmaking.

10. Aluminum is a low-temperature resistant metal. The lower the temperature, the higher the strength. Therefore, aluminum and aluminum are commonly used as refrigerators, refrigerators, Antarctic snow vehicles, hydrogen oxide production devices, etc. For example, our aluminum alloy tray is also a commonly used tray material in cold storage.
