6463 Alloy Corrosion Resistance

Aluminium 6463 has excellent corrosion resistance due to its high content of chromium, which forms a protective layer on the surface. This makes it ideal for use in humid or salty environments such as sea air or high-humidity areas, as it will not corrode easily.

6463 Alloy Heat Resistance

Aluminum 6463 has excellent heat resistance properties due to its high content of chromium, which gives it greater stability at higher temperatures compared to other types of aluminum alloys. This makes it an ideal choice for use in applications where temperatures may exceed 600°F (316°C).

6463 Alloy Heat Treatment

Aluminium 6463 can be heat treated in order to increase its strength and hardness while maintaining its corrosion-resistant properties. The most common way to do this is by quenching and tempering, which involves heating the metal up to approximately 1000°F (538°C) before quickly cooling it down in cold water or oil. This process increases the hardness and strength but also lowers the ductility.

6463 Alloy Machining

Due to its relatively low melting point compared to other metals such as steel, aluminium 6463 can easily be machined into complex shapes using conventional machining techniques such as turning, milling and drilling without any difficulty. Its low friction coefficient also makes it easier to machine than other materials such as stainless steel or titanium alloys.

6463 Alloy Welding

Aluminium 6463 can be welded using TIG welding techniques, typically used when working with thin sheet metal parts or components that require precise control over temperature during welding processes. When welding aluminum alloys, special care must be taken since they are sensitive to cracking if too much heat is applied during the welding process. Therefore it is important that you use low amperage settings when welding aluminium alloys so that they do not crack during the process.


In conclusion, aluminium 6463 is an excellent choice for numerous applications due to its corrosion-resistant properties, heat resistance capabilities, easy machinability, and weldability when using TIG welding techniques with appropriate parameters for temperature control during welding processes. Its low melting point means that it can easily be shaped into complex shapes without any difficulty making it ideal for use in many industries, from automotive manufacturing to aerospace engineering and beyond!
