Can aluminum 6063 be forged?
Yes, aluminum 6063 can be forged. Forging changes aluminum by using heat and pressure. This makes its shape and properties better. Many manufacturers pick aluminum 6063 for forging because it has:
Better resistance to corrosion than some other alloys
A smooth surface, which is good for things you can see
Very good formability for custom extrusion and tricky shapes
6063 is often used in extrusion for building projects. Aluminum alloy 6063 is easy to machine and works well with anodized finishes. Picking 6063 or another aluminum alloy depends on what the project needs for forging, extrusion, or how the surface looks.
6063 Aluminum Forging
Aluminum 6063 is used a lot for forging in many fields. This alloy is known for being easy to shape and for fighting rust. Many companies pick 6063 for both extrusion and forging. It can make tricky shapes and strong parts. Aluminum alloy 6063 can be forged and is often hot forged. This makes its mechanical properties better. Forging 6063 aluminum helps make parts that are tough and last long. These parts work well for buildings and custom jobs.
Hot Forging Process
Forging 6063 is usually done with hot working. The main ways are open die forging, closed die forging, and sometimes cold forging. Each way has its own good points for different jobs.
Open die forging is good for small batches and special shapes. It makes the inside of 6063 better and gets rid of problems.
Closed die forging uses shaped tools to make exact parts. This way is best for making lots of parts. It gives 6063 parts more strength and helps them last longer.
Cold forging shapes 6063 without heat. It makes parts with smooth surfaces and close sizes. This is important for some extrusion and custom jobs.
The main steps in hot forging 6063 aluminum are:
Preheating: Workers heat 6063 to a set temperature. This makes it easier to shape and lowers resistance.
Forging: Machines press on the hot 6063 to shape it.
Cooling: The part cools in a controlled way. This sets its structure and properties.
Heat Treatment: The part may get more heat to make it stronger.
Machining: Workers cut or drill the part to fit the job.
Tip: Careful control of each step in the 6063 aluminum forging process helps stop problems and makes sure the parts are good.
Temperature Range
The temperature for 6063 aluminum forging is very important. Most forging of 6063 happens between 500°F and 950°F (260°C to 510°C). This is lower or about the same as some other aluminum alloys, which often need more heat.
Aluminum Alloy | Typical Hot Forging Temperature Range (°F) |
|---|---|
6063 | |
Other Aluminum Alloys (6000 & 7000 series) | 700 – 950 (some up to 1100) |
This lower temperature makes 6063 a good pick for many extrusion and forging jobs. It also saves energy and helps stop overheating, which can cause problems.
Quality Control and Safety
Forging 6063 can sometimes cause problems like stripe marks, inclusions, or weak grains. These can make the part less strong. To stop these problems, companies must watch the temperature, use pure materials, and check quality at every step. Special tests, like checking hardness and looking at the inside, help find problems early.
Safety is very important in 6063 aluminum forging. Workers must keep out water and dirt, which can cause explosions. They must also be careful with aluminum dust, as it can blow up. Following safety rules and good training keeps everyone safe.
Standards and Certifications
Many fields need forged 6063 parts to meet strict rules. Common certifications are ISO 9001 for quality, ISO 14001 for the environment, and RoHS for keeping out bad substances. ASTM and military rules also cover many 6063 aluminum forging products.
Note: Meeting these rules makes sure 6063 parts are safe, work well, and are ready for extrusion, building, and custom jobs.
Aluminum 6063 Properties
Aluminum 6063 is strong and easy to shape. It is also simple to work with. These traits make it a top pick for forging and other uses. The alloy has magnesium and silicon in it. This mix helps it bend well and fight rust. Because of these features, 6063 works in both hot and cold forming.
Mechanical Strength
6063 gets stronger from its small grains and Mg2Si phase. After forging, it becomes harder and can pull more before breaking. For instance, forging at 300°C makes the grains smaller and the metal harder. The table below shows how heat changes the strength of 6063:
Temper | Treatment Description | Approximate Tensile Strength (psi) |
|---|---|---|
6063-T5 | Air cooled after extrusion + artificial aging | 30,000 – 35,000 |
6063-T52 | Solution heat treatment + cold working + natural aging | ~35,000 |
6063-T6 | Solution heat treatment + artificial aging (full treatment) | ~42,000 |
Forging by itself can make 6063 stronger but less bendy. But if you heat treat it after forging, it gets both strong and bendy. After special heat steps, it can stretch up to 24%. This makes it tough and able to bend without breaking.
Workability
6063 is easy to work with when forging. This is because:
The magnesium and silicon are kept at the right levels for the Mg2Si phase.
New forging ways, like isothermal extrusion, keep the heat and speed just right. This stops cracks from forming.
Cooling with nitrogen makes the surface smoother and keeps it easy to work with.
Its grain structure and low copper help it process better than many other aluminum alloys.
These things let 6063 be made into tricky shapes and thin parts. That is why it is used in buildings and custom jobs.
Heat Treatment
Heat treatment is very important for 6063 after forging. The best way is:
Heat it to about 510°C for 20 minutes, then cool it fast in water.
Age it at 180-185°C for 5 to 24 hours to get the T6 temper, which is the strongest.
Working it cold before aging can make it even stronger and faster to age.
Over-aging (T7 temper) helps it fight rust but makes it less strong.
Doing each heat step carefully makes sure 6063 has the right mix of strength, bendiness, and rust resistance for its job.
6063 vs Other Alloys
6063 vs 6061
6063 and 6061 are both well-liked aluminum alloys, but they are used for different things. 6063 is great for extrusion and forging when you need smooth surfaces and tricky shapes. Many people call 6063 “architectural aluminum” because it looks better and fights rust more than 6061. This is why 6063 is picked for window frames, door frames, pipes, and fancy trim. It can make detailed shapes by extrusion and can be anodized for color or extra protection.
6061 is stronger and is good for parts that hold weight. But 6061 does not look as nice or shape as easily as 6063. If designers want parts that look good and last outside, they often use 6063. Its forging and extrusion skills help make cool designs for railings, trims, and displays.
Note: 6063 is the best pick for buildings and products people see, where looks and rust resistance are more important than strength.
6063 vs 6082
6082 is another strong aluminum alloy, and it is used for big, heavy things. It is stronger than 6063, but it cannot be shaped into detailed parts as easily. 6063 is better for making parts with fine details or smooth surfaces by extrusion and forging. People who make things for cars, boats, and outdoor furniture often use 6063 for these reasons.
The table below shows the main differences:
Alloy | Strength | Surface Finish | Extrusion Complexity | Common Applications |
|---|---|---|---|---|
6063 | Medium | Excellent | High | Window frames, trims, rails |
6061 | High | Good | Medium | Structural parts, frames |
6082 | Highest | Fair | Low | Bridges, cranes, heavy parts |
6063 is special because it is easy to shape, fights rust, and works well in extrusion. These things make it perfect for pretty and building uses. Its forging skills help make parts that look good and work well.

Custom Forged Parts
6063 is also used for custom forged parts. It is picked when looks and easy shaping are important. Car and airplane makers use 6063 for parts that need to look good but do not need to be super strong. Common uses of 6063 t6 aluminum here are door frames, window frames, and radiators.
Part Type | Typical Thickness | Typical Size Range (mm) |
|---|---|---|
Door Frame | 1000-2000 | |
Window Frame | 1-2 mm | 1000-2000 |
Radiator | 1-2 mm | 300-600 |
