Introduction to aluminum

The density of aluminum is lower than that of most metals, which can reduce the weight of automobiles. Aluminum alloys for automobiles can be divided into cast aluminum alloys and deformed aluminum alloys. Cast aluminum alloys are the most used in automobiles, accounting for more than 80%. Deformed aluminum alloys include plates, foils, extrusions, forgings, etc. Cast aluminum alloys have excellent casting properties. The appropriate alloy and appropriate casting method can be selected according to the requirements and economic benefits of the purpose of use, part shape, dimensional accuracy, quantity, quality standards, mechanical properties, etc. Cast aluminum alloys are mainly used for casting engine cylinder blocks, clutch housings, rear axle housings, steering gear housings, transmissions, valve trains, oil pumps, water pumps, rocker covers, wheels, engine frames, brake calipers, oil cylinders and Non-engine components such as brake discs.

What are the advantages of BMW GS 93033 AL5-IIC 1) OH111?

1. Less machining: Since the aluminum profile can be extruded into any complex section, as long as the design is reasonable, the extruded aluminum profile can also be easily assembled, thereby reducing the need for machining.

2. The cost of aluminum profile extrusion die is low: the cost of aluminum profile extrusion die is lower than that of rolling forming and forging of other materials such as steel or iron.

3. Light weight: Extruded aluminum alloy profiles are light in weight, high in strength and durable in use. Compared with aluminum and other materials, the weight of the aluminum structure to achieve the same effect is only about half that of other metal structures.

4. Various surface treatment effects and strong corrosion resistance: through powder or electrophoretic coating, designers can achieve any desired color. Of course, it also includes natural silver or colored anodized film.

How to weld BMW GS 93033 AL5-IIC 1) OH111?

Welding method

Almost all kinds of welding methods can be used to weld aluminum and aluminum alloys, but aluminum and aluminum alloys have different adaptability to various welding methods, and various welding methods have their own application occasions. Gas welding and electrode arc welding methods, simple equipment and easy operation. Gas welding can be used for repair welding of aluminum sheets and castings that do not require high welding quality. Electrode arc welding can be used for repair welding of aluminum alloy castings. Inert gas shielded welding (TIG or MIG) method is the most widely used aluminum and aluminum alloy welding method. Aluminum and aluminum alloy sheets can be welded by alternating tungsten argon arc welding or pulsed tungsten argon arc welding.

Preparation before welding

1. Cleaning before welding: before welding, the oxide film and oil stain on the welding joint of the workpiece and the surface of the welding wire should be strictly removed;

Chemical cleaning The chemical cleaning has high efficiency and stable quality, and is suitable for cleaning welding wire and small-sized workpieces produced in batches. There are two methods of dipping and scrubbing.

2. Backing plate: In order to ensure penetration without collapsing, a backing plate is often used to support the molten pool and nearby metals during welding. The backing plate can be made of graphite plate, stainless steel plate, carbon steel plate, copper plate or copper rod, etc.

3. Preheating before welding: Thin and small aluminum parts generally do not need to be preheated. Preheating before welding can be carried out when the thickness is 10mm~15mm. According to different types of aluminum alloys, the preheating temperature can be 100℃~200℃, and oxygen Heating by an acetylene flame, electric furnace or blowtorch.

Post-weld treatment

(1) The residual flux and welding slag left in the weld and nearby after welding will damage the passivation film on the aluminum surface, and sometimes corrode the aluminum parts, so they should be cleaned up. Workpieces with simple shapes and general requirements can be cleaned by simple methods such as hot water washing or steam blowing.

(2) Post-weld heat treatment Aluminum containers generally do not require heat treatment after welding.

Maintenance ofBMW GS 93033 AL5-IIC 1)  OH111

1. For daily maintenance of BMW GS 93033 AL5-IIC 1) OH111, brushes and other hard objects cannot be used as cleaning tools, and soft cotton yarn and cotton cloth should be selected.

2. To clean BMW GS 93033 AL5-IIC 1) OH111 Water, detergent and soap can be used for , but other organic substances cannot be used.

Conclusion
