Product Description:

1.Structure of Aluminium Coils for Color Coated with Polyester

Aluminium Coils for Color Coated with Polyester are widly used in decoration field. For the painting, it depends on the using evironment.  If you use in the open air, we recommend the PVDF coated aluminium coils. This kind of painting can last 15-20 years.  If you use in the room, we recommend PE coated aluminium coils. The price is much more competitive.Its weight is much lower than steel. So many customers choosed aluminium material instead of steel.

2. Main features of Aluminium Coils for Color Coated with Polyester

a.Competitive price---We have our own mills and can produce mill finished aluminium coils, so we can control the production cost better.

b.Professional after-sale service---We have more than 15 years exportation experience and you need not worry about the exporation problems.

c.Fast delivery time---We can control the delivery time within 35 days.

Q:is there aluminum oxide on the surface of aluminum sheet after being polished by abrasive paper?
aluminum will be oxided as aluminum oxide once being exposed in air.
Q:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
you can use 520 or AB glue, and I think 520 is better.
Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:Could two pieces of aluminum sheets be welded together?
or you can use file to rub back and forth, and it needs lots of practices or you can't weld the sheets.because aluminum sheet cann't be tightly welded to tin, it's hard to weld two pieces of aluminum sheets by common welding methods.it's hard, the aluminum sheets are oxidized soon after polished by abrasive paper.and you need to cover the new polished area with soldering paste and learn some operating skills.owing to aluminum sheets' high oxidized speed, you need to wipe the aluminum sheets with soldering paste and soldering tin and rub them with large power soldering iron, then the aluminum sheets will be tightly welded to tin.so two pieces of aluminum sheets could be welded together.
Q:What's the standard thickness of aluminum sheet?
the thickness of tobacco aluminum foil and red wine bottle cap is designed according to customers demands and manufacturer has no stated specification.
Q:is general aluminum sheet fire-proof?
nonfireproof
Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
Q:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
