Product Description:

Aluminium is a relatively soft, durable, lightweight, ductileand malleablemetalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

Q:Why do the layers loose when taking out coil after roll of aluminum 0.14?
After rolling, the most possible reason may be poor deoiling effect. I think, for 0.14mm aluminum coil, the lining sleeve will not be forgotten. After rolling , oil ooze from aluminum layers, and the support of aluminum coil is not enough, leading to coil collapsing. The specific manifestations are that the edges of even round aluminum layers become like water ripple, and that the aluminum coils suddenly become uneven when taking out coil.
Q:Is aluminum silicate roll felt the same as aluminum silicate acupuncture blanket?
No, the unit weight of aluminum silicate fiber felt is greater than that of aluminum silicate acupuncture blanket. Both are thermal insulation and fire-proof material and have the same function.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:Can the displacement sensor be used for real-time measurement of the aluminum coil thickness?
Yes, you can use two sensors to measure thickness, either contact sensor or laser sensor
Q:Can the 5-10cm thick paper sleeve inside the scrapped aluminum coil be sliced? Now we use knife which is much troublesome.
You can use Long Men Rolling Mill to slice directly.
Q:How to remove the fingerprint and glue residue on the color aluminum coil?
Try to use essential balm. We often use the essential balm to remove glue residue on the stainless steel bowl and basin.
Q:How to purchase PE polyester coated aluminum sheet and PVDF fluorocarbon coated aluminum coil?
Both belong to color coated aluminum sheet and coil. Customers can purchase ordinary aluminum sheet or coil, and then go to special coating company to add PE polyester coating or PVDF fluorocarbon coating. The color is bright and quality is also very good. PE polyester coated aluminum and PVDF fluorocarbon coated aluminum coil has a wide range of usages: construction industry (aluminum-plastic panel, aluminum honeycomb, roof corrugated sheet, fireproof veneer, aluminum ceiling, shutter, rolling shutter door, garage door, awning, water gutter), electronic appliances (computer chassis, computer panel), lighting, furniture, solar reflector, air conditioning duct and the like. At present it is still applied in many areas including electronic appliance, instrument, lighting, packaging and house decoration.
Q:What are the compositions of aluminum coil coating?
The common compositions are crylic resin, solid inorganic filler, different pigments, flatting agent and so on.
Q:Can aluminum coil 3003H24 replace 3A21H14?
Yes.
Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
