3105 aluminum vs 3004

3105 Aluminum SheetPre-painted Finishes offer extreme durability in outdoor exposure as well as indoors because of our high-quality paint system. Pre-painted aluminum sheet finishes are uniquely designed in that they offer a hard, abrasive resistant coating, yet allow the flexibility for extensive forming and fabricating.

Aluminum Alloy 6061 coils and sheets are the most versatile of the heat treatable aluminum alloys. Though less strong than most of the 2000 and 7000 alloys, 6061 aluminum provides an extensive range of mechanical properties and corrosion resistance and can be fabricated by many of the commonly used practices. In the “O” temper or annealed condition, alloy 6061 has good formability. In the T4 condition, fairly severe forming can be done; whereas, in the T6 condition, properties may be obtained by artificial aging.

6061 aluminum sheet alloy is strong, easily machined, and weldable. Aluminum 6061 T6 alloys are doubled the strength of aluminum 6063 alloys. Aluminum 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa). In thicknesses of 0.250 inch (6.35 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties. The famous Pioneer plaque was made of this particular alloy. Order 6061 Aluminum Sheets in 6061 Aluminum in small quantities and no minimums of all Aluminum 6061 at The Metal Store.

3004-O aluminum is 3004 aluminum in the annealed condition. It has the lowest strength and highest ductility compared to the other variants of 3004 aluminum. The graph bars on the material properties cards below compare 3004-O aluminum to: 3000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it’s 50% of the highest, and so on.
