6060 Aluminum profile for automotive sun roof and seat guide

Aluminum alloy automotive sun roof have been made widely with aluminum profiles, and more used in wagons and multipurpose vehicles. The front and rear seats occupy a large proportion of the car body quality. The use of extruded aluminum section to make the seat frame can greatly reduce the quality of the vehicle without changing the traditional design. The seat track is made of complex hollow section profile, which shows that it has changed from sliding structure to impact linkage system, which improves the safety of the car.

An automotive sun roof is an operable (tiltingor sliding) opening in an automobile roof which allows light and /or fresh air to enter the passenger compartment. Sun roofs may be manually operated or motor driven, and are available in many shapes, sizes and styles.Sunroofs, by historical definition are opaque and slide open to allow fresh air into the passenger compartment. The first sun roofs were folding sun roofs , i.e. the panel made of fabric folds back as it slides open. Today, however, most factory-installedsliding sun roof options feature a metal or -more and more-a glass panel.

Top-mount sliding sun roofs have been a popular factory option in the past, but are now generally replaced by inbuilt systems. In top-mount versions,large glass panels slide open in tracks on top of the roof, with no loss of headroom.In built sun roof systems have a panel which slides between the metal roof and interior headliner, requiring some loss of headroom, but providing a full opening in the roof. Sun roof systems are available in many shapes, sizes and styles, and are known by many names: Pop-up sun roofs consist simply of a tilting panel. These panels are often removable, and must be stored when removed. The tilting action provides a vent in the roof, or a full opening when the panel is removed.

Spoiler sun roofs combine the features of a pop-up with those of a sliding roof system. They tilt to vent, but can alternatively slide open.
Panoramic roof systems are a newer type of large or multi-panel sun roofs which offer openings above both the front and rear seats and may be operable or fixed glass panels.

Solar sun roofs have an inlaid photovoltaic solar insert which makes the glass totally opaque. While they operate identically to conventional factory - fitted glass sunroofs (tilting and retracting), the solar panel provides electricity to power the interior ventilation fans for cooling the car interior on hot days when the car is standing outside in the sunlight.

Lightweight aluminium components are a favoured solution for the design of the sun roof opening mechanism. Automobile companies generally use aluminium extrusions to make sun
roof channels. Sun roof channels basically form part of a sliding system, i.e. the channels must have a smooth surface, show low friction and must be resistant to wear. Some manufacturers anodise the surface of these channels to produce a layer of aluminium oxide in order to improve the wear resistance. Furthermore, extruded profiles for sun roof channels have to meet high geometrical tolerances. Thus, a tight shape control of the extrusions is required.Aluminiumguide rails for sun roofs are typically made from EN AW-6060 extruded profiles. The extrusions are cut, bent, heat treated, punched, CNC milled, de-burred and finally surface treated.

6061 Aluminum bar for automotive brake system

Brake system parts require high corrosion resistance. Aluminum extrusion profiles are the first choice for making such parts. The corrosion resistance of materials is not high. Once corrosion occurs, it will cause brake failure. In the brake booster, brake valve, brake valve, ABS dispersion parts, piston are 6061 alloy extrusion machinery processing, the section is 106mm * 26mm rectangular bar. Henan Chinalco successfully produced the ABS valve body rectangular rod for automobile using the reverse extrusion machine and reverse extrusion technology. It is difficult to batch production of this 6061 aluminum alloy rectangular bar, with strict requirements for various technical specifications, high precision in size and strict requirement for coarse crystal ring.

As stated above, aluminium components are often found in the hydraulic system. These components have to satisfy highest safety requirements. Therefore in general, only wrought aluminium alloys and the respective product forms are used, for example forged or impact extruded parts. Often, components are also machined from extruded profiles with properly designed cross sections.

Aluminium components in the actual braking units at the wheels reduce the unsprung mass,but due to their corrosion resistance also ensure problem-free long term operation.

Additional aluminium application potential can be found in the brake lines. The brake fluid travels from the master cylinder to the wheels through a series of hydraulic tubes and reinforced rubber hoses. The rubber hoses are used only in places that require flexibility, such as at the front wheels, which move up and down as well as steer.

6063 T6 Aluminum profile for automotive roof rails

Another important application of aluminium extrusions are roof rails. Roof rails are placed on the top of the vehicle and are used to carry additional luggage and equipment. Aluminium extrusions are used for manufacturing roof rails because they enable visually attractive, low weight and high strength designs. The length of aluminium roof rails can vary significantly, they are found on small cars as well as
on station wagons and MPV's (Multi Purpose Vehicles).
Roof rails have two principle functions; to enhance the design features of the vehicle and to carry extra loads placed on the roof, often with the help of another structure, e.g.transverse load bars or a roof box.

The typical roof rail has two cast supports with an extruded aluminium bar between them.It is also common to use an intermediate support for longer rails or where the design loads are high. The extrusion process provides almost limitless possibilities for the designer to choose a section that satisfies functional and esthetical demands. A subsequent stretch bending step offers additional
design freedom. Casting offers similar freedom of design for supports. Supports are typically joined to the extruded bar by mechanical joining or by adhesive bonding. Byhydroforming the rail,it is also possible to integrate the end supports with the extrusion and thereby eliminate the cast supports thus reducing the number of parts and enhancing design.

There are different possibilities for surface finishing of aluminium roof rails,in particular electrochemical polishing and anodizing. Depending on material and/or alloy, surfaces ranging from high-gloss to matt, from natural-colored to black aluminum are achieved by different processing options. Another possibility is powder-coating with matt or high-gloss lacquers.

Most of the new developments of roof rails are so called "flush rails". Flush rails are bent and machined extrusions which are integrated with the roof trim. There are no cast end supports, but only a bent and machined extrusion which isfixed flush to the roof trim.The alloy EN AW-6060 is generally used for the flush rails.

The luggage roof rails is located in the roof, by 3D precision bending processing, materials for tensile strength more than 200N/mm² - 6063 T6, the material requirements are: extrusion, cold forming and cutting were good, to meet the three-dimensional precision bending and distortion requirements section.

Aluminum Step is required on the decorative parts, 6063-T5 alloy can choose good gloss and surface treatment ability of the extruded material also has high requirements on the size precision of the section.

The high-gloss surface appearance of anodized strips underlines the top quality, dynamic design of the luxury and high performance vehicles. Therefore,"high gloss packages"are particularly prominent with upper class models and sport cars.Popular are for example tread plates for the door sill. Tread plates are usually made from the Extrusions alloys EN AW-6060 or 6063; the extruded profiles are cut, pressed, CNC-milled,scratch-brushed / polished and anodized.
