Aluminum alloy 4047 is a wrought aluminum alloy with a composition that includes both aluminum and silicon. It belongs to the 4000 series of aluminum alloys, which are known for their high silicon content. The alloy is primarily used for welding applications due to its excellent weldability and fluidity.
Here are some key features and applications of 4047 aluminum alloy:
Key Features:
Weldability: 4047 is widely recognized for its excellent weldability. It is often used as a filler material in welding applications, especially when joining aluminum alloys.
Fluidity: The alloy has good fluidity during welding processes, allowing for smooth and uniform welds.
Corrosion Resistance: While not as corrosion-resistant as some other aluminum alloys, 4047 exhibits decent resistance to atmospheric corrosion.
Thermal Conductivity: 4047 has relatively high thermal conductivity, making it suitable for applications where heat dissipation is important.
Low Melting Point: The alloy has a relatively low melting point, which can be advantageous in certain welding applications.
Applications:
Welding Filler Material: 4047 is commonly used as a welding filler material for joining various aluminum alloys. Its compatibility with different aluminum base materials makes it valuable in the welding industry.
Brazing: The alloy is also used in brazing applications, particularly in the automotive and heat exchanger industries.
Heat Exchangers: Due to its good thermal conductivity, 4047 is employed in the production of heat exchangers.
Radiators: The alloy is used in the manufacturing of aluminum radiators, where its weldability and thermal properties are beneficial.
Automotive Components: 4047 may be utilized in the fabrication of certain automotive components, particularly those that require welding or brazing.
It's important to note that 4047 is primarily used as a filler material in welding and brazing applications rather than in its pure form for structural purposes. When selecting an aluminum alloy for a specific application, it's essential to consider the mechanical and thermal properties required, as well as the compatibility with the base materials being joined.
