Aluminum comes in several alloy series for different extrusion requirements. The widely used 6063 alloy suits applications where a good surface finish is a priority, while 6061 offers greater strength for structural needs, with yield strengths of around 145 MPa for 6063-T5 and around 240 MPa for 6061-T6.
Buyers often look for an Indonesia aluminum factory that manages its own processes from melting through extrusion. Billets can be adjusted to the requested alloy series, so the choice between 6063 and 6061 is made at the start of production, across Exalummetal industrial aluminum products from heat sinks to four other commonly sought profiles.
1. Heat Sink
Heat sinks serve equipment that needs to release heat, including high-power LED housings, inverters, transformers, amplifiers, computing devices, and 5G base stations. Black anodizing is recommended because it increases surface emissivity and improves heat dissipation through radiation.
Heat sink is available in sizes from compact to heavy-walled. Section 96012 measures 33.50 mm wide and 28.00 mm high, with a 1.90 mm wall thickness and a weight of 0.568 kg per meter, the thickest wall of the 11 sections. Section 96008 measures 23.40 by 17.00 mm, has a 1.00 mm wall, and weighs 0.331 kg per meter.
2. Flat Bar
Flat bar is used for machined components, structural supports, electrical busbars, and architectural trims. Anodized finishes are available in clear, black, and custom colors.
Flat bar is available in sections with very different proportions. Section 10083 is 38.00 mm wide and 19.00 mm thick, with a 2.00 mm corner radius and a weight of 1.947 kg per meter. Its thickness is half its width. Section 10309, by contrast, is 100.00 mm wide but only 1.50 mm thick.
3. Spandrel
Spandrel profiles are used for exterior soffits, ceiling panels, wall cladding, and gas station canopies. The profile is non-combustible, making it a fire-resistant option for these applications.
Spandrel is available in nine sections with different heights. Section 62020 measures 97.00 mm wide and 9.30 mm high, with a wall thickness of 0.80 mm and a weight of 0.260 kg per meter. Its height is the second greatest of the nine, after section 98108. This comparison helps narrow the options when profile height matters.
4. Equal Angle
Equal angle profiles are used for corner protection, structural frameworks, architectural edging, shelving, and brackets. Finishes include standard mill finish, clear anodized, and custom powder-coated colors.
Equal angle is available in different leg lengths and thicknesses. Section 20090 has legs measuring 38.10 mm, a thickness of 0.90 mm, and a weight of 0.184 kg per meter. Section 20043 weighs the same per meter, even though its legs measure only 18.00 mm and its thickness is 2.00 mm. The comparison shows why dimensions and weight are useful to review together.
5. C Channel
C Channel, also called unequal channel, is used for framing light panels and as a guide rail on panels and sliding doors. It can also protect the edges of plywood, MDF, glass, and composite panels.
C Channel is available in light and wide sections. Section 31021 measures 15.20 mm wide, with 9.10 mm legs, a 1.00 mm wall, and a weight of 0.085 kg per meter. Section 32052 measures 38.10 mm wide, with 25.40 mm legs, a 0.90 mm wall, and a weight of 0.212 kg per meter, about 2.5 times heavier per meter.
