Product Description:

1.Structure of Product Description

 

PE Coated aluminium coils 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. However, the price of PE Colored aluminium coils is much more competitive than PVDF aluminium coils. So many customers prefer PE coated aluminium coils.

 

2. Main features of the product

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:Why aluminium plate warp after sandblasting?
I don't know about aluminium or metallurgy but I have direct experience of grinding and lapping silicon wafers for the integrated circuit industry. I know that these grinding-type processes (and I think sand blasting may be similar) will introduce stress on the machined side of a thin silicon plate. The damage affects the atomic scale silicon lattice (aluminium will be similar only it may be polycrystalline as opposed to the single-crystal lattice with which I am familiar). This stress acting on one side of the plate causes the plate to bend or warp. For the theory behind plate bending due to stress try googling Stoney's equation. Note that this stress and usually the warpage might be removed by performing the same operation on the opposite side of the plate (the stresses induced then cancel each other). For silicon we can also reduce or remove the stress by polishing away the machined surface.
Q:how to solder to aluminium?
Yikes, this post is chock full of misleading information. Of course it's possible. How do I know? I do it 6-8 hours a day. Lead/tin and tin/copper solders bond to aluminum very well, they just don't bond to aluminum oxide. This soldering can be done by exposing fresh aluminum through scoring, scraping or sanding, then quickly soldering. Or use a purge box like we do - exclusion of oxygen solves the issue nicely, but an initial capital expense is required. Please - if you don't know, don't answer. It degrades the usefulness of the site.
Q:How to sell the super hard 5083aluminum alloy and 5083 aluminum coil?
Among the alloy which cannot endure heat treatment, 5083 aluminum alloy, a kind of high magnesium alloy, has the properties of intensity, machinability, anti-corrosion, electric-arc weldability and aesthetic after anodizing. The main element of 5083 alloy being magnesium, it is endowed with corrosion resistance, weldablility and moderate intensity, thus applicable to maritime areas such as ships, and cars, airplane weldments, metro light rail, and pressure vessel (such as liquid tank truck, refrigerated truck, refrigerated container), refrigerating equipment, television tower, drilling equipment, transport facility, missile parts, armor and so on.
Q:Test for nitrates - Reduction by aluminium?
Aluminum is an active metal and wants to be ionized. Al -- Al(3+) + 3e(-) ın basic media, tetrahydroxoaluminate complex will be formed: Al(3+) + 4OH(-) -- Al(OH)4(-) ======================================... Al + 4OH(-) -- Al(OH)4(-) + 3e(-) Nitrate is reduced to ammonia in basic media, ammonium in acidic media: N(5+) + 8e(-) -- N(3-) NO3(-) + 8e(-) + 10H(+) -- NH4(+) + 3H2O in basic media, we add base (OH-) to both sides: NO3(-) + 8e(-) + 11OH(-) + 10H(+) -- NH4(+) + 3H2O + 11OH(-) NO3(-) + 8e(-) + OH(-) + 10H2O --- NH3 + 4H2O + 10OH(-) ======================================... NO3(-) + 8e(-)+ 6H2O -- NH3 + 9OH(-) Now, to the balancing of these two redox half reactions: Al + 4OH(-) -- Al(OH)4(-) + 3e(-) NO3(-) + 8e(-)+ 6H2O -- NH3 + 9OH(-) ============================= 8Al + 32OH(-) -- 8Al(OH)4(-) + 24e(-) 3NO3(-) + 24e(-) + 18H2O -- 3NH3 + 27OH(-) ================================== 8Al + 3NO3(-) + 32OH(-) + 18H2O -- 8Al(OH)4(-) + 3NH3 + 27OH(-) //////////////////////////////////////... 8Al + 3NO3(-) + 5OH(-) + 18H2O -- 8Al(OH)4(-) + 3NH3 Hope this helps.
Q:melting aluminum?
aluminum, in general, will just oxidize if heated in air. it is not just cans that behave that way when they (alcan, alcoa) smelt aluminum industrially they keep it in a reducing environment and do not allow molten aluminum to contact air. so use any aluminum you like but prevent it from contacting air.
Q:The export aluminum volume is CIF. If there is no insurance policy, how will the customs premium be collected?
The customs will not charge your premium the premium you can write but if you are a refund if there will be some impact because of the tax rebate minus the freight and insurance premium so you consider the premium but you can write less Never mind if you need shipping or shipping insurance declaration business can contact me oh
Q:Impact strength of aluminium 2024 composite after cryogenic?
Aluminum 2024 doesn't have a transition temperature, it absorbs about 18n-m impact strength (via charpy tests I ran three weeks ago at my College course). This was constant between -150ºC to +150°C (liquid nitrogen to a furnace). This excerpt from wiki: Cutting tools In 1982 at the Oak Ridge National Laboratories, George Wei, Terry Tiegs, and Paul Becher discovered a composite of aluminium oxide and silicon carbide whiskers. This material proved to be exceptionally strong. Development of this laboratory-produced composite to a commercial product took only three years. In 1985, the first commercial cutting tools made from this alumina and silicon carbide whisker-reinforced composite were introduced by the Advanced Composite Materials Corporation (ACMC) and Greenleaf Corporation. Leads me to believe it depends on how you mix the material in would make a difference. Silicon Carbide and aluminum make very strong tools, but would make it more brittle. The ceramic in a metallic crystal lattice (metal is a crystalline structure) would allow more voids to coalesce leading to a brittle fracture, but the initial strength would be improved because of substitution dislocations in the crystal structure (it would be more rigid, stronger, but more prone to sudden failure). Silicon carbide has low thermal expansion coefficient compared to aluminum also so when it gets really cold the aluminum would contract around the particles increasing the strength, but again, reducing ductility and causing fractures to occur more rapidly. Anyways, very interesting, you should do a bit of research on your own after this as I gave you some good places to work from (and I'm sure plenty of words to look up ;D )
Q:What is the balanced equation for copper (I) oxide and Aluminum?
Copper(I) oxide is a solid and so is aluminum. Any reaction that might occur would have to be at an elevated temperature. This is a thermite reaction in which copper(I) is reduced to copper metal (molten) and aluminum is oxidized to aluminum oxide. 3Cu2O(s) + 2Al(s) -- 6Cu(s) + Al2O3(s) ========= Follow up ========== Do you mean in aqueous solution? There won't be any copper(I) chloride in aqueous solution. CuCl is very insoluble in water, but will undergo disproportionation to form Cu2+ ions and copper metal. Therefore, you would actually have a solution of copper(II) chloride. Copper(II) chloride will react with aluminum to form copper metal and aluminum ions. Ordinarily aluminum won't react with copper(II) ions. The reaction does proceed in the presence of chloride ion. This is because the chloride ion will react with the Al2O3 layer on the surface of aluminum metal to make [AlCl4]^- which exposes the aluminum metal below, and thus a reaction can occur. 3Cu2+ + 2Al(s) -- 2Al3+ + 3Cu(s)
Q:IS aluminium oxide passive (non-reactive) (plz read below too)?
Not sure. Maybe because Na K are more active than Aluminum.
Q:Aluminum Frame M1911 question...?
Alloy is great for one thing. Making a gun lighter to carry around. If it was something I was going to shoot substantial amounts of ammo through, I would stick with a caliber that is a bit lower pressure-wise. No +P ever! You can expect about half the life a steel frame would give you. There are many 1911's in 38 Super with alloy frames. How many are shot out is another matter. Personally, I really wouldn't worry about it unless you are burning through more than say 100 rounds a month. Even at that, it should be 15 or 20 years before you would have to worry about it. If it's going to be a competition gun, ditch the alloy frame in favor of a steel one. The added weight will help minimize muzzle climb.
