With its excellent surface quality and attractive appearance, aluminum alloy 6463 is an extremely popular choice for cosmetic and decorative purposes. It is highly malleable and creates a bright sheen when anodized and polished. We’ll discuss what makes aluminum alloy 6463 what it is and how it is commonly used in various industries.
Due to its highly polished shine, aluminum alloy 6463 is often used for commercial construction projects, such as in appliances or remodels for kitchens and bathrooms, as well as for imparting an upscale aesthetic to shops and other facilities. Aluminum alloy 6463 is a common choice for shop fittings and trims as well as for trim, rims, and emblems for OEM and aftermarket auto parts.
Advantages of Aluminum Alloy 6463
Though aluminum alloy 6463 is very similar to alloy 6063, alloy 6463 is more suitable for rigorous anodizing processes. This gives it a much greater aesthetic appeal than alloy 6063, and aluminum alloy 6463 is an affordable and more attractive alternative to stainless steel when structural support is not necessary.
Anodized Aluminum 6463
With a professionally applied and even anodizing process, aluminum alloy 6463 becomes ideal for decorative purposes. The anodizing process entails treating the aluminum with an electrochemical process, which not only creates a brilliant luster but greater durability, as well. This durability comes from the fact that the chemical treatment causes an anodic layer to form from the metal itself, making it a single material rather than a layer of multiple different materials.
The anodized surface will not chip or flake – and the finished product is three times thicker than the original, non-anodized aluminum. This also gives it greater color stability, and the brightness that results in an intrinsic part of the metal itself, so it will not lose its luster or require further treatments as it ages. Further, aluminum is one of the most plentiful and affordable metals on the planet, making anodized metal a highly cost-effective solution that is at once attractive and more robust than other untreated aluminum alloys.
After the electrochemical treatment process, aluminum 6463 is a unique alloy with the following chemical composition:
- Aluminium: 97.9 to 99.4%
- Copper: 0.2% max
- Iron: 0.15% max
- Magnesium: 0.45 to 0.9%
- Manganese: 0.05% max
- Silicon: 0.2 to 0.6%
- Zinc: 0.05% max
- Residuals: 0.15% max
Because the anodizing process thickens the material, aluminum 6463 has higher tensile strength than other aluminum alloys while still maintaining a high degree of yield strength and flexibility. This enables it to withstand forces that might otherwise break a more brittle metal or bend thinner aluminum products. Further, aluminum alloy 6463 has a greater density than non-anodized aluminum but is still a very lightweight metal, making it easy to work with and install.
Here are the principal mechanical properties of aluminum alloy 6463 that set it apart from other aluminum alloys:
- Density: 2.69 g/cm3, or 168 lb/ft3.
- Young’s modulus: 70 GPa, or 10 Msi.
- Ultimate tensile strength: 130 to 230 MPa, or 19 to 33 ksi.
- Yield strength: 68 to 190 MPa, or 9.9 to 28 ksi.
- Thermal expansion: 22.1 μm/m-K.
