Brushed aluminum sheet is a flat metal panel with a textured surface. The texture comes from fine abrasive lines running in one direction. This gives the metal a soft, satin look. It hides fingerprints. It reduces glare. It adds a modern, industrial feel to any product.
Buyers often ask about alloy types, temper states, and whether brushed aluminum can survive outdoors. This guide answers those questions. We compare 5052 and 6061 alloys. We explain H32 and H34 tempers. We list applications, thickness options, and custom size services.
What Is Brushed Aluminum Sheet?
Brushed aluminum sheet starts as a standard aluminum coil or plate. A brushing machine uses abrasive belts or wire brushes to create fine parallel lines on the surface. The process removes minor flaws and gives the metal a uniform, directional texture.
The result is not mirror-bright. It is not matte-flat. It sits in between. The brushed surface catches light in a gentle way. It feels smooth to the touch but looks textured to the eye.
Brushed aluminum sheet can be used as-is. It can also be anodized, painted, or laminated after brushing. The brushing step is often the first stage in a multi-step finishing process.
Why Choose Brushed Aluminum Sheet?
Brushed finish offers unique benefits that other surface treatments do not match.
Fingerprint and Smudge Resistance
The fine lines scatter light. Fingerprints blend into the texture. This makes brushed aluminum ideal for products that people touch often. Appliances, elevator panels, and handrails stay cleaner longer.
Scratch Hiding
Small scratches on a brushed surface are less visible than on a polished or glossy surface. The existing texture masks minor damage. This is why high-traffic areas use brushed metal.
Modern Aesthetic
The linear grain gives a clean, industrial look. It suits contemporary architecture, electronics, and furniture. Designers like the balance between raw metal and refined finish.
Cost Efficiency
Brushing costs less than anodizing or mirror polishing. It adds visual value without a big price jump. For budget-sensitive projects, brushed aluminum sheet is a smart choice.

Temper H32 vs H34 for 5052 Brushed Sheet
Within the 5052 alloy, temper choice affects performance. H32 and H34 are the most common for brushed sheet.
H32 Temper
H32 is strain-hardened and then stabilized by low-temperature heat treatment. It is about quarter-hard.
| Property | H32 Value |
|---|---|
| Tensile Strength | 230 MPa min |
| Yield Strength | 195 MPa min |
| Elongation | 12% min |
| Formability | Very Good |
H32 is the default choice for brushed aluminum sheet. It bends well. It forms well. It still has enough strength for most applications.
H34 Temper
H34 is strain-hardened to half-hard. It is stronger than H32 but less formable.
| Property | H34 Value |
|---|---|
| Tensile Strength | 260 MPa min |
| Yield Strength | 215 MPa min |
| Elongation | 10% min |
| Formability | Good |
H34 is used when the part needs more rigidity. It is common for panels that must stay flat under load. It is also used when H32 is too soft for the application.
H32 vs H34 Decision Guide
| Need | Choose H32 | Choose H34 |
|---|---|---|
| Bending and forming | Yes | No |
| Maximum strength | No | Yes |
| Flatness under load | No | Yes |
| Welding after forming | Yes | Less ideal |

Can Brushed Aluminum Sheet Be Used Outdoors?
This is a common question. The answer depends on the alloy, the environment, and any post-brushing treatment.
Bare Brushed Aluminum Outdoors
Bare brushed aluminum can be used outdoors. But it has limits. Aluminum forms a natural oxide layer. This layer protects against mild weather. However, it is thin and uneven. In harsh environments, bare aluminum will:
- Develop white oxidation spots
- Lose its brushed luster over time
- Show water stains and pollution marks
- Pit in coastal or industrial areas
Bare brushed aluminum is fine for short-term outdoor use. It is also acceptable in mild climates. For long-term outdoor exposure, extra protection is needed.
Protected Brushed Aluminum Outdoors
Adding protection extends outdoor life significantly.
| Protection Method | Expected Outdoor Life | Best For |
|---|---|---|
| Clear anodizing | 10–20 years | Trim, facades, signage |
| Color anodizing | 10–15 years | Architectural panels, branding |
| Powder coating | 15–25 years | Heavy structural, marine |
| PVDF coating | 20–30 years | High-end architecture |
| Protective film | 1–3 years temporary | Transport, storage |
Clear anodizing over brushed aluminum is the most popular outdoor treatment. It preserves the metal texture while adding a hard, sealed layer. The oxide pores are closed. Water and salt cannot penetrate.
Outdoor Use by Environment
| Environment | Bare Brushed | Anodized Brushed | Coated Brushed |
|---|---|---|---|
| Indoor only | Good | Excellent | Excellent |
| Mild outdoor, dry climate | Fair | Very Good | Excellent |
| Urban outdoor, rain | Poor | Good | Very Good |
| Coastal, salt spray | Very Poor | Good | Very Good |
| Industrial, chemical | Poor | Fair | Good |
| Marine, submerged | Not recommended | Fair | Good |
For coastal or marine use, 5052 alloy with clear anodizing or powder coating is the minimum. 6061 should be coated or anodized for any outdoor use.

Frequently Asked Questions
Can brushed aluminum sheet be used outdoors without coating?
Bare brushed aluminum can survive outdoors in mild climates. But it will oxidize and lose its look over time. For long-term outdoor use, clear anodizing or powder coating is strongly recommended. In coastal areas, bare aluminum is not suitable.
What is the difference between H32 and H34 temper?
H32 is softer and more formable. H34 is stronger but less formable. H32 is the standard for brushed sheet. H34 is used when extra stiffness is needed. Both are strain-hardened tempers for 5052 alloy.
Is 5052 or 6061 better for brushed sheet?
5052 is better for forming, welding, and marine use. 6061 is better for machining, strength, and structural parts. For decorative panels that need bending, choose 5052. For brackets and machined parts, choose 6061.
Can I get brushed aluminum sheet in custom sizes?
Yes. Most suppliers offer custom cutting. You can order exact lengths, widths, and even complex shapes. Standard coil widths limit the maximum width. But slitting and shearing can produce almost any size within those limits.
Does brushing affect the thickness of the sheet?
Brushing removes a very small amount of material. The thickness change is usually less than 0.02 mm. For most applications, this is negligible. If tight tolerances are needed, specify the final thickness after brushing.
Can brushed aluminum be welded?
Yes. Both 5052 and 6061 weld well. Brushing does not affect weldability. However, the brushed texture may hold contaminants. Clean the weld area before joining. After welding, the heat-affected zone may lose its brushed look. Touch-up brushing may be needed.
How do I clean brushed aluminum sheet?
Use a soft cloth and mild soap. Wipe in the direction of the brush lines. Avoid circular motions. Do not use abrasive cleaners or steel wool. These can create cross-scratches that show clearly on the directional texture.
What is the maximum size for brushed aluminum sheet?
Standard mill coils are up to 1500 mm wide and 3000 mm long. Some mills can produce up to 2000 mm wide. For larger panels, seaming or joining is needed. Check with your supplier for their specific mill limits.
Can brushed aluminum be colored?
Yes. Brushed aluminum can be anodized and dyed. The brush texture remains visible under the color. Popular colors include black, bronze, champagne, and blue. The color absorbs into the anodized pores and is sealed for durability.
Is brushed aluminum more expensive than mill finish?
Yes, but the difference is small. Brushing adds one processing step. The cost increase is typically 10% to 20% over mill finish. Compared to anodizing or mirror polishing, brushing is very economical.
What alloys can be brushed?
Almost all aluminum alloys can be brushed. 5052, 6061, 3003, 1100, and 1050 are the most common. Harder alloys like 7075 can be brushed but require more aggressive abrasives. Very soft alloys like 1060 brush easily but may show uneven texture.
How long does brushed aluminum last?
Indoors, brushed aluminum lasts decades with minimal care. Outdoors, bare brushed aluminum may show aging in 2 to 5 years. With anodizing or coating, outdoor life extends to 10 to 30 years depending on the environment and protection level.
Brushed Aluminum Sheet Material
Brushed aluminum sheet is a versatile material with a distinctive look. It combines the light weight of aluminum with a texture that hides wear and adds style. Alloy 5052 offers excellent formability and corrosion resistance. Alloy 6061 brings higher strength and machinability. Temper H32 is the go-to choice for general work. Temper H34 adds stiffness when needed.
Custom sizes are widely available. Whether you need thin decorative sheet or thick structural plate, suppliers can cut and finish to your exact specs. The key is to match the alloy, temper, thickness, and finish to your specific application.
If you need brushed aluminum sheet for your next project, start by defining the environment, the forming needs, and the visual goals. Then choose between 5052 and 6061. Pick the right temper. Select the thickness. And decide whether outdoor protection is needed. With these choices clear, you will get a product that performs well and looks great.
