　　Nowadays, aluminum extruded housings are ubiquitous in industry, and they can be used for a variety of purposes, such as protecting electronic components, providing structural support, conducting thermal energy, etc. The selection of aluminum extruded housings varies according to the application. In order to select the best aluminum extruded housings, it is necessary to consider the design requirements, process requirements and performance requirements.

　　The design requirements of aluminum extruded housings include external dimensions, internal space dimensions and the position of openings/holes. The external dimensions determine the external shape of the aluminum extruded housing, which is usually square, circular or elliptical. The internal space dimension determines the internal space required for the mounting of components, which usually include printed circuit boards, optical components, cores, resistors, diodes, relays, connectors and LEDs. The position of the openings/holes on the aluminum extruded housing determines the position of the openings/holes on the aluminum extruded housing, which can be used for ventilation or connection inside the aluminum extruded housing.

　　The process requirements of aluminum extruded housings are related to the materials of aluminum extruded housings. The materials of aluminum extruded housings include stainless steel, galvanized steel, aluminum alloy, nickel alloy, copper alloy and plastic. Stainless steel housings have good corrosion resistance, but are heavy. Galvanized steel housings have poor corrosion resistance, but are light in weight. Aluminum alloy housings are light and corrosion-resistant, but easily damaged. Nickel alloy housings prevent electronic components from overheating, but are expensive. Copper alloy housings have good thermal conductivity, but are heavy in weight. Copper alloy housings have good thermal conductivity, but are prone to rust. Plastic housings are light and economical, but not corrosion-resistant.

　　The performance requirements of aluminum extruded housings mainly consider environmental requirements, electrical requirements and thermal requirements. Environmental requirements mainly consider operating temperature, storage temperature and humidity. Electrical requirements include rated voltage and rated current. Thermal requirements mainly consider insulation performance, thermal conductivity performance and thermal expansion performance.

　　The selection of aluminum extruded housings is a complex process, which requires the consideration of design requirements, process requirements and performance requirements. With this information, you can select the best aluminum extruded housing according to your requirements.
