Extruded Aluminum Bar
Highly regarded by elite machine shops and milling center experts around the world, ACC-U-LINE® products by Sapa Extrusion feature the industry’s best machinability, unsurpassed dimensional tolerances and consistent, controlled grain structure. Our extruded aluminum bar stock allows machinists to achieve lighter weight, high-strength physical and mechanical designs with an attractive appearance and corrosion-resistant finish, as well as offering good acceptance of applied coatings and excellent joining characteristics.
As the largest soft alloy extruder in North America, we utilize state-of-the-art indirect presses and an exacting process to produce the ACC-U-LINE® rod and bar product line. Indirect extrusion reduces the frictional heat generated by extrusion, and enables us to produce a premium product. This line of extruded rod, bar and hex products, available in 6061, 6082, 6042 and 6262 free machining alloys, provides higher speeds and feed rates, increased machine efficiencies and improved recovery of machined parts, thereby lowering operating costs for screw machine operations and machining centers and preventing tool wear.
ACC-U-BAR® aluminum bar stock is available in square and rectangular extrusions in a variety of sizes - square bar from 0.875" to 8.000", and rectangular bar from 1.000" x 1.500" to 7.000" x 8.000". The entire ACC-U-LINE® product family is also available in a variety of tempers, and features a fine recrystallized uniform grain structure. Larger cross sectional areas feature an unrecrystallized uniform grain structure, ensuring that our products deliver an unmatched uniformity compared with other extruded products on the market.
6061 aluminum alloy is one of the most useful heat-treatable alloys for aluminum bar stock, offering structural strength, a good surface finish, good corrosion resistance to atmosphere and sea water, superior machinability, and it can be easily welded and joined. 6061 alloy products are heat-treatable and are used extensively as a construction material, most commonly in the manufacture of marine and automotive components. 6061-T6 aluminum bar stock has a very high strength-to-weight ratio, making it ideal for large parts that need to be very light.
Another outstanding choice for medium strength, extreme corrosion resistance, weldability, brazeability, and machinability is alloy 6082. This heat-treatable alloy responds well to surface finishing, anodizing and painting, and 6082 bar stock is ideal for high stress applications, such as cranes, bridges and trusses, transport applications, scaffolds and platforms.
Sapa Extrusions’ unique capabilities include in-house casting of special alloy chemistries, enabling us to create uniform grain and microstructure with our advanced processing and heat-treating equipment. Our products deliver a consistent and dependable uniformity unsurpassed by any competing extruded product available.
As the leader in extruded aluminum stock production, Sapa is able to offer the widest variety of product choices to meet the needs of our customers’ challenging project requirements. ACC-U-LINE® extruded aluminum bar products are available from Sapa Extrusions and our Premier® Distributor Partners.
