Aluminum scrap

Belonging to aluminum magnesium silicon alloy, it is widely used, especially in the construction industry. It is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, medium strength.

1. The application of strips is widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries.

2. Aluminum materials for aerospace are used to manufacture aircraft skins, fuselage frames, main beams, rotors, propellers, fuel tanks, wall panels and landing gear pillars, as well as rocket forging rings, spacecraft wall panels, etc.

3. Aluminum for transportation is used for body structures of cars, subway vehicles, railway passenger cars and high-speed passenger cars, car doors and windows, shelves, car engine parts, air conditioners, radiators, body panels, wheels and ships.

4. All-aluminum cans mainly use thin plates and aluminum foil as metal packaging materials to make cans, lids, bottles, barrels, and packaging foils. Widely used in the packaging of beverages, food, cosmetics, medicines, cigarettes, and industrial products.

5. Printing aluminum is mainly used to make PS plates. Aluminum-based PS plates are a new type of material in the printing industry and are used for automatic plate making and printing.

6. Aluminum alloys for architectural decoration are widely used in building frames, doors and windows, suspended ceilings, decorative surfaces, etc. because of their good corrosion resistance, sufficient strength, excellent process performance and welding performance. Such as various building doors and windows, aluminum profiles for curtain walls, aluminum panels for curtain walls, pressure panels, decorative panels, color-coated aluminum panels, etc.

7. Aluminum for electronic home appliances is mainly used in various bus bars, wires, conductors, electrical components, refrigerators, air conditioners, cables and other fields. Specifications: round rod, square rod

Representative applications include aerospace fixtures, electrical fixtures, and communication fields, and are also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board tin, etc.
