Aluminum is an extremely popular choice for sheet metal suppliers due to its cost effectiveness, flexible nature, and range of options and grades. For example, high strength aluminum can be specialized for the aerospace industry, while corrosion resistant aluminum alloys are ideal for marine applications. It is highly weldable, machinable, and weather resistant. Common grades of aluminum include: Grade 1100-H14 — This aluminum grade offers the best ductility for welding and deep draws, but the lowest strength. It’s commercially pure, with high chemical and weather resistance, making it popular for chemical processing applications. Grade 3003-H14 — Stronger than the 1100 grade, this type of aluminum is still formable, low cost, weldable, and corrosion resistant. It is popular for storage solutions such as cabinets or tanks, and lends itself well to stamping and drawing. Grade 5052-H32 — A much stronger aluminum sheet, 5052 still offers weldability, corrosion resistance and good formability, though it’s best for applications such as tanks or chassis. Grade 6061-T6 — Less formable and weldable than the other grades, 6061 is a heat-treated structrual aluminium alloy that is ideal for aircraft applications. It is the strongest of this list, and can also be found in yachts, automotive parts, bicycles, and firearms. Due to its flexibility and many variations, aluminum sheet metal is an excellent material choice for both structural and mechanical applications. Even a specialized alloy such as 6061 can be further manipulated through tempering to produce particular strength or weldability.
the 5052 aluminum alloy is used to make beverage closure without internal pressure. The raw material is 5052 H19 aluminum sheet, the material is first oxidized to improve the coating adhesion and corrosion resistance. After the two sides are painted, the can lid is formed. So 5052 aluminum is another material for processing closures. 5052 aluminum sheet has good oxidation coloring effect, excellent metal texture and hardness, wear resistance and corrosion resistance, long service life, and is widely used in high-end mobile phone casings, high-end air-conditioning casings and other fields with high requirements for oxidation and metal texture.
Aluminum 2014 is a precipitation hardening alloy with fair corrosion resistance, high electrical conductivity, and good machinability. As one of the strongest aluminum alloys on the commercial market, 2014 Aluminum is heavily used in the manufacture of aircraft and truck parts, as well as in forging applications. 2014 alloy is primarily aluminum based, with copper being the other major element. Standard specifications for 2014 include ASTM B209, UNS A92014 and more.
