5049 alloy is a non-strengthened deformed aluminum alloy after heat treatment. In recent years, when our company produces
5049 aluminum coil sheet plate, defects such as cracks and cracks often appear, especially when using heat-insulating molds to cast long slabs. The trend is particularly serious.
In order to avoid this phenomenon, we adopted a new process: ensure Fe>Si; add aluminum titanium boron wire online; ensure uniform water cooling
The pouring temperature is 700-710℃, the liquid level is 60-75mm; the lubrication of the mold should be done well.
The 5
049 aluminum coil sheet plate made by this method has the following characteristics:
Good corrosion resistance. Resistance to acid and alkali corrosion, so that the 5 series aluminum plate is suitable for the environment that most aluminum plates cannot adapt to, and greatly expands the application range of aluminum.
2. Good processability. It has high plasticity and good processing performance.
5049 aluminum coil sheet plate can be adapted to various processing methods such as bending, stamping and stretching.
3. Good thermal conductivity. It has good thermal conductivity and is a material for manufacturing equipment shells and radiators.
4. Strong resistance to pressure. The aluminum alloy plate can be further processed to increase its strength. It is the main material for making mobile phone and computer casing.
