No, 6063 aluminum is not magnetic. It is a non-ferrous alloy, meaning it contains no iron and does not respond to magnetic fields under normal conditions. This non-magnetic property makes 6063 aluminum ideal for applications where magnetic interference must be avoided, such as in medical imaging equipment, electronic enclosures, and precision navigation instruments.
Why Is 6063-T5 Aluminum Not Magnetic?
To understand why 6063-T5 aluminum does not attract a magnet, we must look at its basic metallurgy and atomic structure.
Magnetism in metals is primarily a property of ferromagnetic materials. Ferromagnetic materials include iron, nickel, cobalt, and some rare earth alloys. In these metals, the magnetic moments of their atoms naturally align parallel to each other, creating a strong, permanent magnetic field.
6063 aluminum is composed primarily of aluminum (over 97%), with small additions of magnesium and silicon to increase its strength and extrudability. Because it lacks any ferromagnetic elements, its atoms do not align to create a magnetic field. Technically speaking, aluminum is classified as a "paramagnetic" material. This means it has an extremely weak, barely measurable attraction to a magnetic field, but this reaction is so minuscule that, for all practical industrial and engineering purposes, 6063 aluminum is entirely non-magnetic.
- Aluminum = Non-ferrous metal
- No iron or nickel = No ferromagnetism
Summary: 6063 aluminum is non-magnetic because it lacks ferromagnetic elements, making it inert to magnetic attraction.
Can 6063 Aluminum Profiles Become Magnetic?
A common question from engineers is whether mechanical processing or extreme conditions can change this property.
- Under normal conditions: No. Bending, extruding, or artificially aging the aluminum to a T5 or T6 temper does not change its non-magnetic nature.
- In very strong magnetic fields: It will exhibit a negligible paramagnetic response that can only be detected by highly sensitive laboratory equipment. A standard permanent magnet or electromagnet will not stick to it.
- Factory Contamination (The "False Magnetism" Issue): In real-world industrial settings, buyers sometimes report that a magnet faintly sticks to their aluminum profile. This is rarely the aluminum itself. Usually, it occurs because the aluminum was cut with a saw blade or processed on a CNC machine that previously cut steel. Microscopic iron dust embeds into the soft aluminum surface, causing a false magnetic response.
Summary: 6063 aluminum remains effectively nonmagnetic in practical applications, provided strict factory cleanliness prevents iron contamination during machining.
Magnetism Comparison of 6063-T5 Aluminum vs Other Metals
When designing equipment for sensitive environments, selecting the right non-magnetic material is crucial. Here is how 6063 aluminum compares to other common industrial metals.
| Material | Magnetic Property | Industrial Note |
| Aluminum (6063-T5) | Non-magnetic | Ideal for extrusion, lightweight framing, and enclosures. |
| Carbon Steel | Magnetic | Highly magnetic; cannot be used near sensitive electronics. |
| Stainless Steel (304/316) | Sometimes magnetic | Austenitic grades are mostly non-magnetic, but cold working (like bending) can induce slight magnetism. |
| Copper / Brass | Non-magnetic | Excellent for electrical components, but heavier and more expensive than aluminum. |
Summary: Aluminum behaves similarly to copper in terms of magnetism, offering a highly reliable non-magnetic structure without the risk of cold-work-induced magnetism found in some stainless steels.
Advantages of Non-Magnetic 6063 Aluminum Extrusions in Industry
The inability to hold a magnetic charge is not a weakness; in many high-tech industries, it is the primary reason 6063 aluminum is specified.
1. No Electromagnetic Interference (EMI)
In modern electronics, stray magnetic fields can distort signals, corrupt data, and cause circuit malfunctions. Because 6063 aluminum is non-magnetic, it does not trap or emit magnetic fields, making it the perfect housing material for sensitive circuit boards and communication devices.
2. Safe for Medical Equipment (MRI Zones)
Magnetic Resonance Imaging (MRI) machines generate incredibly powerful magnetic fields. Any ferromagnetic metal brought into an MRI room can become a deadly, high-speed projectile. 6063 aluminum is entirely safe to use for structural framing, patient beds, and ventilation grilles within these restricted zones.
3. Uninterrupted Precision Navigation
In marine navigation and aerospace, compasses and sensitive gyroscopes must operate without local magnetic deviation. Non-magnetic aluminum framing ensures these instruments read true geographic data without interference from the vessel's structure.

Common Applications Requiring Non-Magnetic 6063 and 6061 Aluminum
Because it combines non-magnetic properties with a lightweight structure and excellent corrosion resistance, 6063-T5 aluminum (and its stronger counterpart, 6061-T6) is heavily utilized in the following sectors:
- Electronics Enclosures: Server racks, inverter housings, and telecommunications boxes.
- Medical Equipment: Structural frames for hospital beds, MRI room shielding, and diagnostic machine chassis.
- Cleanroom Automation: Robotic arms and structural T-slot framing in semiconductor manufacturing facilities where magnetic dust attraction must be minimized.
- Architectural Profiles: While not strictly required for magnetism, 6063 is the standard for window frames and curtain walls due to its surface finish, with the added benefit of not interfering with indoor Wi-Fi or radio signals.
