Sheet Type
Perforated Aluminum Sheet
Corrugated Aluminum Sheet
Series 1xxxis essentially pure aluminum, Aluminum content is above 90%. With excellent workability, high corrosion resistance, electrical conductivity, and weldability.
Types of sheet metal:
Typical Applications: Widely used in products with low strength processing, industrial applications, fin-stock, decorative and household applications, nameplates, etc.
Series 2xxx is Al-Cu, Al-Cu-Mn alloys with high strength and fatigue resistance. Forging alloy, good forge ability, and high strength, but poor corrosion resistance.
Typical Applications:Aircraft structural components, especially under the wing and fuselage structure, and parts for the transportation industry.
Series 3xxx is Al-Mn alloys with excellent formability, good weldability, and corrosion resistance.
Types of sheet metal:
Typical Applications: this is the most widely used of antirust aluminum. Mainly used for fuel tanks and petrol pipe insulation. Others used for basic materials for roofing metal, decorative trim, cooking utensils, kitchen equipment, awnings, siding, chemical equipment where slightly higher strength than Series 1000 is required.
Series 4xxx is an Al-Si alloy with a low melting point, good melt fluidity, easy to feed, and will not make the final product brittleness.
- Types of sheet metal:
- 4343/3003/7072 Aluminum Brazing sheet
Typical Applications: Mostly used in forging, building, mechanical parts, and welding materials.
Series 5xxxis an Al-Mg alloy with good strength, excellent corrosion resistance, cutting well in the non-heat treatment alloy.Excellent workability, excellent finishing characteristics with bright, clear anodize coatings.
Types of sheet metal:
Typical Applications:Wide variety from aircraft components to home appliances, marine, and transportation industry parts, heavy-duty cooking utensils, and equipment for bulk processing food.
Series 6xxxis an Al-Mg-Si alloy with the most versatile of the heat treatable alloys with excellent formability, weldability, machinability, medium strength, and good operability after annealing.
Types of sheet metal:
Typical Applications: Engineering and structural applications, boats, furniture, Truck bodies and frames, Running boards.
Series 7xxxis an Al-Zn-Mg-Cu alloy with super-hard aluminum alloy. It is strong with high strength and average machinability but has less resistance to corrosion than many other Al alloys.
Types of sheet metal:
Typical Applications: Used mostly in aircraft and transportation industries where strength is critical.
Series 8xxxhas a similar performance with Series 1xxx, but internal malleability is better.
Types of sheet metal:
Typical Applications: Widely used in the heat-sink device, lid stock, aluminum foil, Air-Condition foil.
Two different processing of Aluminum sheet metal fabrication
1. Different forming process:
Casting-rolled is processed by casting & rolling into cast roll (6-8mm thickness) and then processed by cold rolling line, while hot rolling is heated by aluminum alloy billet (400-500mm thickness), which is rolled by hot rolling mill.
3. Different properties:
the surface quality of the hot-rolled aluminum sheet is better, and the mechanical properties and ductility are stronger, which is suitable for the anodized and deep drawing fabrication process;
5. Different prices:
the process of casting-rolled aluminum sheet metal is simple, and the price is cheaper than that of hot-rolling aluminum sheet metal.
Hot rolling Vs Continues Casting rolling
First of all, most customers who have experience in sourcing sheet metal materials from China should know that there are differences in the performance and price of the finished product caused by the difference between two different fabrication processes, mainly for series 1xxx and series 3xxx. For the finished products of series 1xxx and 3xxxx, what we should compare is not the difference between the fabrication process of hot rolling and cold rolling, but the fabrication process of finished products of hot rolling and cast rolling.
2. Different raw material supply:
the difference between the two is that the billet supply is different. The hot-rolled billet is cast aluminum ingot–heated–rolled into a coil for cold rolling, and the cast billet is cast rolled coil–cast rolling;
4. Different applications:
casting-rolled aluminum metal sheets are mostly used for building decoration and other common civilian purposes. Hot-rolled aluminum metal sheets are suitable for areas requiring deformation of the plate surface such as stamping and stretching;
6. Different finished products:
the elongation of the casting-rolled products of the same alloy grade is lower than that of the hot-rolled products, and the cast-rolled products are limited by the rolling force of the casting & rolling machine and can only produce Aluminum metal sheets of series 1xxx, 3xxx and 8xxx.
