Aluminum Extrusion Alloys
Sapa Extrusions, North America’s leading supplier of extrusion profiles, has an extraordinary capacity for producing all standard and custom aluminum extrusion alloys and tempers, shapes and sizes, by both direct and indirect extrusion, through our nationwide network of production and supply facilities.
Our team of experts applies their decades of experience to developing solutions for virtually any unique application. We also have unprecedented resources and the ability to create custom alloys for customers.
While the majority of our alloys are within the 6000 series, we extrude a wide variety of aluminum alloys, including:
1060 Alloy. This is a relatively low strength, essentially pure, non-heat treatable aluminum alloy. It is noted for its excellent welding characteristics and formability along with good corrosion resistance. It has excellent forming capability by cold or hot working with commercial techniques and may be welded by standard commercial methods. Typical applications include chemical and food handling equipment, as well as containers for food, pharmaceuticals and liquids.
3003 Alloy. Another of the non-heat treatable alloys, alloy 3003 features good corrosion resistance, workability and weldability. It develops strengthening from cold working only. Alloy 3003 is readily machined and considered to have good machinability for the aluminum alloys. It also has excellent resistance to chemical attack and is commonly used for heat exchangers and condensers that involve chemicals.
6042 Alloy. This new alloy was developed to provide machine shops with unmatched in consistency and tolerance control. It also has lower lead levels that comply with ELV and RoHS environmental directives when products are recycled. It offers better machinability than 6061 alloy and is an excellent alternative to 6262 alloy, which exceeds the .4% maximum lead level. It is commonly used for electrical connectors and screws, air conditioning components, manifolds and valve blocks, brake components, and fasteners and hardware.
6061 Alloy. This magnesium and silicon alloy is the best choice when welding or brazing is required. It has structural strength and toughness, good corrosion resistance and good machining characteristics. It has an excellent appearance after anodizing. 6061 is used extensively as a construction material, most commonly in the manufacture of marine and automotive components.
6063 Alloy. This popular magnesium and silicon alloy is in the heat treatable category. It has a finer grain structure than 6061 and will provide the best cosmetic appearance after anodizing. It is highly corrosion resistance with good workability and weldability. Common uses include cylinder tubing, electrical bus conductor, and architectural applications.
6262 Alloy. This heat treatable alloy is one of the few alloys developed specifically for its excellent machinability. It is also one of the most corrosion resistant alloys and easily accepts all types of anodic coatings (clear, clear and dye, hardcoat, etc.), which will enhance its resistance to corrosion and wear. It is readily weldable by all gas, arc and resistance methods and can also be brazed. Alloy 6262 is commonly used in the manufacture of automotive and marine applications.
Other alloys and applications include:
Sapa Extrusion, the world’s leading soft alloy aluminum extruder, produces all standard and custom 6000 series aluminum alloys and tempers, shapes and sizes, by both direct and indirect extrusion, including 6082 aluminum alloy, which has been gaining popularity in the U.S. for structural rod, bar and tube profiles.
Aluminum is available in a wide variety of alloys to meet specific requirements. Pure aluminum is soft and malleable, and most applications require greater strength than pure aluminum can provide. Sapa Extrusion offers structural 6xxx series alloys, such as 6005 aluminum and 6005A aluminum, which can be used in designs requiring moderate strength and excellent corrosion resistance.
Aluminum is one of the most used conductive materials in the manufacture and construction of electrical power distribution components and equipment. As a heat treatable wrought alloy, 6101 aluminum is best suited to these applications, which require moderate strength and maximum electrical conductivity. Alloy 6101 is an important alloy in Sapa Extrusion's full line of bus conductor extruded products.
As the world’s leading soft alloy aluminum extruder, Sapa Extrusions provides a comprehensive suite of services for clients in virtually all industrial, commercial and consumer markets. We design and manufacture extrusion tooling using the latest technology and CAD/CAM design.
Our expert staff of metallurgists and engineering, manufacturing, design and marketing specialists can provide the aluminum extrusion alloys and other services you need for your unique application.
