4A03 aluminum alloy belongs to the 4000 series of aluminum alloys. Silicon (Si) is the main alloying element. It is mainly used as an additive material for aluminum alloy welding, such as brazing plates, welding rods and welding wires. This series of alloys has good wear resistance and high-temperature performance, so it can also be used to manufacture heat-resistant materials and architectural decorative items.

4A11 aluminum alloy (LD11) is mainly used to manufacture components that have high requirements for strength, corrosion resistance and wear resistance, including automotive parts, high-strength structural components in the aerospace field and engine parts, as well as mechanical components such as steam engine pistons and cylinders with low thermal expansion coefficient.

4A13 aluminum alloy is mainly used as a hard brazing filler metal for plates and strips, especially for the brazing layer of radiator brazing plates and foils. It belongs to the aluminum-silicon alloy series and is suitable for directly producing products such as plates, strips, foils, and welding wires.

4A17 aluminum alloy (the former name was LT17) is an aluminum-silicon alloy, mainly used for covering plates for brazing and welding wires, as well as for directly manufacturing products such as plates, strips, and foils.

4004 aluminum alloy is mainly used as a brazing coating material, welding additive material and casting material for aluminum alloys. Its high silicon content gives it a low melting point, good fluidity and good shrinkage filling ability, which makes it highly suitable for manufacturing the skin material of aluminum brazed sheet foil and as a filler material for welding. In addition, it is also used to manufacture wear-resistant mechanical parts and castings, such as pump bodies and valve bodies, as well as components like pistons that require high dimensional stability.

4032 aluminum alloy is mainly used to manufacture components that require high temperature strength, wear resistance and dimensional stability, such as pistons and cylinder heads of automotive engines, as well as high-performance components in the aerospace field. Due to its content of up to 12% silicon, it has excellent high-temperature resistance, wear resistance and a low thermal expansion coefficient, making it an ideal choice for high-performance engine components and materials requiring precise processing.

4047 aluminum alloy is mainly used as a filler alloy for welding and brazing, as it contains a high proportion of silicon (11-13%), with a low melting point, good fluidity and excellent corrosion resistance. The high silicon content also helps to reduce the shrinkage and hot cracking of the weld. This alloy is suitable for high-temperature environments, especially in the manufacturing of components such as automotive engine blocks and microwave integrated circuits, and is also commonly used in the production of electronic devices, seals and gaskets.
