Applications of aluminum alloys in the automotive industry

Aluminum alloys are widely used in the automobile industry and are mainly used in the manufacture of various parts of automobiles, including body, engine, suspension system, rims, etc. Here are some specific applications:

1. Body and frame: The lightweight properties of aluminum alloy make it widely used in the manufacture of body and frame. Using aluminum alloys can significantly reduce the overall weight of a car, thereby improving fuel efficiency and reducing emissions.

1. Engine parts: The high thermal conductivity and excellent corrosion resistance of aluminum alloys make it very popular in the manufacture of engine parts. For example, aluminum alloys can be used to make engine cylinder heads, pistons, and radiators.

4. Rim: The lightweight and beautiful appearance of aluminum alloy make it very popular in the manufacture of rims.

5. Other components: In addition to the above components, aluminum alloys are also used to manufacture other components of automobiles, such as fuel systems, braking systems, electrical systems, etc.

In general, the application of aluminum alloys in the automotive industry can improve the fuel efficiency, performance and durability of the vehicle, while also improving the aesthetics of the vehicle.

Aluminium Extrusion Working Principle:

During extrusion, under the strong extrusion force, the ingot is divided into several strands of metal by the knife (bridge part) of the mold and flows into the mold welding chamber. Under the conditions of high temperature, high pressure and high vacuum, the metal is re-welded and flows from the die hole to the needle. It flows out from the formed gap to form a hollow product of the required shape and size. The number of welds in the product is the same as the number of strands of metal flow.

Wire Electrical Discharge Machining

It belongs to the category of electric processing.

When the couple of the former Soviet Union Lazalianke studied the phenomenon and cause of the damage of the switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can make the local metal melt, oxidize and be corroded, thus creating And invented the electric discharge machining method.

The wire cutting machine was also invented in the former Soviet Union in 1960, and our country was the first country to use it in industrial production.

EDM wire cutting machine can be divided into reciprocating type:

High Speed Wire cut Electrical Discharge Machining

Low Speed one-way walk Wire cut Electrical Discharge Machining

Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire.

It can also be divided into single column cross table type and double column type (commonly known as gantry type) according to the form of workbench.

Saw Machine

The circular saw band is tensioned on two saw wheels, and the saw wheels drive the saw band to cut. There are two main types of band sawing machines: vertical and horizontal.

The saw frame of the vertical band sawing machine is set vertically, and the workpiece moves during cutting, which is used to cut the curved contour of the sheet and formed parts. The saw band can also be replaced with a file chain or abrasive belt for repairing or grinding.

The saw frame of the horizontal band sawing machine is arranged horizontally or obliquely, and is fed in the vertical direction or in the direction of swinging around a point. The saw band is generally twisted by 40° to keep the saw teeth perpendicular to the workpiece.

Horizontal type is divided into scissors type, double column, single column type band sawing machine; according to the use situation, it can be divided into manual type (economic type, manual feeding and manual cutting of materials), automatic type; according to the automation program using the controller, it can be divided into manual type ( Semi-automatic manual feeding) Fully automatic type (automatic feeding and automatic cutting)
