6063 aluminum sheet plate

What is 6063 aluminum sheet

6063 aluminum sheet is an aluminum alloy with magnesium and silicon as alloying elements. 6063 aluminum sheet generally has good mechanical properties and can be heat treated and welded. The comprehensive performance requirements of aluminum alloy are far higher than the industry standard.

The strength of 6063 alloy is lower than that of 6061 aluminum, and it has good extrudability, corrosion resistance and good surface treatment performance. 6063 belongs to the low alloy Al-Mg-Si series high plasticity alloy. It has many valuable functions.

6063 aluminum sheet plate chemical composition

The density of 6063 aluminum alloy is 2.69g/cm3.

The role of elements in 6063 aluminum sheet

• 1. The role of magnesium (Mg) element: Mg and Si in Si metal first generate AlFeSi, AlFe (Mn) Si, and the rest generate Mg 2Si, and there is still extra time to generate free silicon (Si), but if silicon (Si ) Insufficient magnesium ( Mg ) produces excess time Mg 2Al 3 . The weight ratio of Mg and Si in Mg 2Si is Mg: Si=(2×24.3)/28.1=1.73; 24.3 is the atomic weight of magnesium; 28.1 is the atomic weight of silicon. The weight ratio of (Fe Mn) and Si in AlFe (Mn)Si is (Fe Mn): Si=55.8 55/28.1=3.94 ≈4; where 55.8 55. The atomic weight of iron is the atomic weight of manganese. Therefore, the amount of silicon (Si) that actually generates Mg 2Si is total Si-0.25 (Fe Mn), which is why the content of iron (Fe) and manganese (Mn) should be controlled in the ingredients.
• 2. Silicon (Si) effect: the generation of Mg 2Si Excessive silicon can play a strengthening role (Si) is soluble in the matrix (the solubility of silicon in aluminum at 550°C can reach 1.65%). Precipitation of fine particles at room temperature has a strengthening effect, but it will reduce the extrusion performance, and the excess silicon (Si) is often controlled not to exceed 0.2%; when the silicon (Si) is insufficient, the excess magnesium (Mg) will generate Mg 2Al 3 , which will reduce the processing performance.
• 3. Copper (Cu) function: very little copper is dissolved in the matrix, and the precipitate during aging is small, preventing adverse effects caused by waiting before aging; a large amount of copper will form CuAl 2 phase; many times it becomes Al -Cu-Mg-Si alloy (hard aluminum).
• 4. Chromium (Cr) function: it is beneficial to improve the tensile strength and forming, and refine the grain.
• 5. Iron (Fe) function: not more than 0.15%, otherwise the surface will turn gray after oxidation.

Melting and casting process of 6063 aluminum sheet

• 1. Ingredients: According to the set Mg2Si, how much magnesium is estimated to be needed for excess Si? (Mg), silicon (Si) control iron (Fe) and then test aluminum ingots in front of the furnace, the scrap contains silicon (Si), magnesium (Mg), and the amount of iron (Fe) determines the amount added.
• 2. Melting: prevent silicon (Si) from sinking to the bottom and slagging, and magnesium (Mg) from burning on the floating surface and absorbing hydrogen.
• 3. Refining: add refined cryolite Al 2O3 to dissolve and remove it in the form of scum, release chlorine and combine with hydrogen to form HCL to prevent secondary pollution caused by impure nitrogen (including O2, H 2O), pure N2.
• 4. Casting: temperature, speed, water pressure, and water temperature depend on the on-site operators to find the best conditions and fix them in the form of files.
• 5. The slag removal operation is carried out at about 735°C, which is conducive to the separation of slag and liquid.
• 6. Refining generally adopts the secondary refining method, the primary refining adds solid refining agent, and the secondary refining adopts the gas refining method.
• 7. Generally, it needs to be casted in time after 30min-1h after the furnace is turned down, otherwise it needs to be refined again.
• 8. During the casting process, it is necessary to continuously add Ai-Ti-B to refine the grains.

Several key parameters in the melting and casting process: the furnace temperature is generally set at 1050°C during smelting, and the metal temperature is controlled not to exceed 770°C.

The melting and casting process of 6063 aluminum sheet is introduced above. After the material is melted at high temperature, it is directly cast into a product. It is generally dissolved in an electric arc furnace, then poured into high temperature resistant casting, and then cooled to crystallize, annealed or cut into products.

In production, mainly by controlling the melting atmosphere, melting temperature and cooling conditions to ensure high production efficiency, meet the requirements of crystal analysis, and form a network structure.
