      What is the Aluminum Coil?

      Aluminum coil is the most important rolled aluminum product. The common aluminum sheet & plate, the Aluminum roll is usually made of aluminum coil cutting. As an important Aluminum raw material of industrial, commercial, and consumer products, aluminum coils can be used in air conditioners, automobiles, airplanes, furniture, structural parts, and many other products.

      What’s the difference between Hot rolled Aluminum coil and Continues casting coil?

      Different applicable alloys

      Due to  the different strengths of each alloy series and the rolling force of the continuous casting and the rolling machine is limited, the alloy series suitable for continuous casting and rolling are only: 1, 3, 8 series.

      The hot rolling process can produce hot rolled aluminum rolls of all alloys because of its strong rolling force at high temperatures.

      Different uses

      Cold-rolled aluminum coil & roll is mostly used in mold class and other general industrial and decorative use., the hot-rolled aluminum coil is suitable for stamping and deep drawing that industries required.

      The difference in performance

      The hot-rolled aluminum coil has a more uniform surface quality and better comprehensive performance and has stronger mechanical properties and ductility, which is suitable for further surface anodized.

      What’s the key properties for High precision & quality aluminum coil?

      In order to secure subsequent continuous Aluminum sheeting process, sheet material must be even, flat and free from buckles, swellings etc such that is able to entirely touch down to a flat surface when laid out with no stress applied.

      Unflatness magnitude shall not exceed 10 I-Unit. To be able to calculate I-Unit magnitude, wave height and wave length will be measured (see fig.1) according to EN or ASTM standard and I-Unit= (π/2.h/L)2×105 formulation will be used for calculation; where “H” is wave height, “L” is wave length and π is the mathematical constant.

      Side view of wave height and length

      Figure 1. Side view of wave height and length

      Maximum crossbow value (H/W) of 5 mm/1.000 mm is permitted (see fig.2). Lateralbow (fig. 3) shall not exceed 2 mm/2.000 mm whereas 4 mm/1.000 mm coilset magnitude is the maximum allowable limit. Measurements will be conducted in accordance with EN 485-4.

      Since the visual appearance of finished products is of high importance in terms of both aesthetic and functionality points of view, surface of the aluminum coil to be does have to have a high degree of clean lines and purity. Thus, existence of oxides, segregations, holes, stains, water stains, oil stains, scratches, bubbles, roll marks, chatter marks, orange peeling, color differences or any kind of impurity is not accepted. Incidents like grain growth or appearance difference etc. On surface are not tolerable in case they adversely affect the visual quality of finished product. Surface must be uniform.

      Surface dirtiness, which is composed of both organic and inorganic (oil, smudge, oxide etc.) constituents, shall not go beyond 20 mg/m2 (sum of both surfaces). Measurement of dirtiness is carried out by weighing a sample with a certain surface area before and after cleaning with an appropriate solvent. Scale to be used shall have a precision of 0,1 mg at least. Difference of before and after weighings is divided by the surface area of the specimen to obtain dirtiness level.

      Loose winding is not condoned. Axial shifting of layers (see fig. 4) and telescoping over the whole coil are not permitted. (see fig. 5).

      Axial shifting

      Figure 4. Axial shifting

      Telescoping

      Figure 5. Telescoping

      Due to extreme length of continuous coil flattening line strip breaks, which always leads to long downtime causing substantial amount of yield loss, are not bearable at all.Therefore, coils having dents either on the sides or on the surface are not acceptable in order to prohibit breaks.Similarly edge cracks and edge build-up defects are not tolerable due to aforementioned reason and also they further likely to cause roll damage.

      Packaging must be done in a manner that prevents coils from corrosion, external effects and atmospheric conditions. Sufficient amount of desiccant must be properly placed in the package in order to prevent oxidation resulting due to the possible condensation of the moisture in the package.

      Coils can be placed “eye to wall” or “eye to sky”position on wooden palette. Wooden palettes must be able to protect coils from damages, while lifting and delivering operations with crane or forklift.
