The 6105 aluminum rod is known for its good corrosion resistance and medium strength, available in two temper states: 6105-T1 and 6105-T5. The T1 temper is suitable for bending, while the T5 temper offers higher mechanical performance.
The higher silicon content in the 6105 alloy makes it easier to machine, making it particularly suitable for manufacturing complex-shaped products.

Various anodizing processes for 6105 aluminum bar
The 6105 aluminum alloy exhibits good anodizing properties, making it compatible with various aluminum anodizing processes.
- Clear Anodizing: Preserves the natural metallic color of the aluminum alloy, suitable for applications where appearance is important.
- Colored Anodizing: Enhances aesthetics, widely used in construction and consumer products.
- Hard Anodizing: Creates a thicker oxide layer, improving wear resistance, suitable for high-durability applications.
Machining recommendations for 6105 aluminum bars
Machining 6105 aluminum is relatively straightforward; however, it requires higher cutting speeds compared to other aluminum alloys due to its higher strength and hardness.
It is recommended to use carbide tools specifically designed for machining hard materials (such as titanium or stainless steel), as these tools have superior wear resistance compared to standard HSS tools, effectively increasing machining efficiency.
Additionally, using coolant can significantly reduce tool wear and extend tool life, as it helps dissipate heat generated during the cutting process more effectively.
Therefore, selecting the right tools and machining conditions will help optimize machining results and improve production efficiency.
Welding recommendations for 6105 aluminum bars
- Preheat the Material: It is essential to preheat the material before welding to prevent cracking due to thermal shock.
- Choose Appropriate Filler Material: Depending on the type of welding process, use either 4043 aluminum filler rods or 5356 aluminum filler rods.
- Post-Weld Heating: After welding, it is crucial to perform post-weld heating on the workpiece to prevent cracking caused by improper cooling rates.
- Strength Reduction: The heat from welding may reduce the strength of the welded area.
