Chalco's 4047 Aluminum Sheet Customer Case Study:
A customer originally used a 6061 aluminum alloy cover with a thickness of 1.5mm for their microwave receiver. The traditional welding method resulted in a wide weld seam.
Later, the housing structure was redesigned using 6061 and 6063, with the 4047 aluminum sheet selected for the cover. Laser seam welding was used to ensure packaging strength and sealing performance. This allowed the cover thickness to be reduced to 1.0mm or even thinner.

Why is 4047 aluminum sheet ideal for laser welding?
Laser welding principles and advantages
Laser welding creates a small heat-affected zone and produces high-quality weld seams. It enables automated production, making it perfect for high-precision applications such as microwave components and electronic packaging.
High silicon content and welding benefits of 4047 aluminum
4047 aluminum sheet has excellent fluidity and a low melting point, enhancing weld density and airtightness. It reduces internal porosity and thermal cracks, ensuring stronger welds.
It also enables efficient lap and butt welding with 6061, 6063, and other housing alloys, ensuring long-lasting and reliable products.
Key considerations for laser welding
- Pre-treatment: Remove oxide film and oil from the surface to ensure optimal welding quality.
- Power and speed control: Example parameters (e.g., 0.5mm cover plate, 1800W laser) provide reference settings.
- Shielding gas selection: Use pure argon or helium to minimize oxidation and enhance weld strength.
Differences between 4043 and 4047 aluminum sheet
- 4043 aluminum sheet contains 5% silicon, whereas 4047 aluminum sheet contains 12% silicon.
- The solidus temperature of 4043 aluminum is 573.8°C, and its liquidus temperature is 632.2°C. In contrast, 4047 aluminum has a solidus temperature of 576°C and a liquidus temperature of 582°C.
- 4047 aluminum sheet has higher crack resistance, while 4043 aluminum sheet has lower crack resistance.
- 4047 aluminum is stronger, capable of withstanding approximately 1, 000 psi of force/impact, whereas 4043 aluminum sheet cannot.
- For elongation applications, 4047 aluminum sheet requires more annealing to achieve better results.
