Why should you choose the aluminum roofing sheet Posted by: KamorkasOa - 07-25-2018, 07:02 AM - Forum: aluminium faq - No Replies The [b]aluminum roofing sheet[/b] is also called the corrugated aluminum plate, pressed aluminum plate, corrugated aluminum sheet or aluminum tile,  it is one of the commonly used products in building, currently, it is more and more popular and has a tendency to replace stainless steel and iron plate. Comparing with the common aluminum sheet, the aluminum roofing sheet has many advantages, the first is the density of it is smaller than the iron, so the weigh of it is light than the iron sheet and the stainless steel. Besides, the aluminum sheet has a good anti-rust effect, the exposing to the rain, sun and the snow won’t cause rust to it, unlike the iron, which will get rust if it is in wet environment. The [b]aluminum roofing sheet[/b] has a long durability, if it is properly used, it can last for 25 to 50 years, some even can last for 50 years, some aluminum roofing sheetcan be coated with special chemicals, which will stop the growth of the algae and mildew, they are also can resist the rot and rust, and the insects like the termites. The aluminum roofing sheet can replace the stainless steel material, and it is very popular in the construction industry. The Haomei industrial Co., Ltd gained much experiences in this field, the aluminum roofing sheet produced by it has been sold to many countries, if you have any demand for the aluminum roofing sheet, please contact us!   Talk about the common sense of the pure aluminum sheet Posted by: KamorkasOa - 07-25-2018, 06:57 AM - Forum: Knowledge & Technique - No Replies The lowest aluminum content of the pure [b]aluminum sheet[/b] shall be determined by the final number of the series code of the aluminum sheet, for example, the last two number of the 1050 series are 50. According to the world standard, the aluminum content must reach the 99.5%, and then it can be called the qualified product. The technology standard of the aluminum alloy in (gB/T3880-2006)also clearly stipulate the aluminum content must be over 99.5%, and it is the same to the other series of the aluminum sheet. There are many advantages in the pure aluminum, first, it can be strengthened, the strength can be increased through the cold processing, and the element of Mg, Zn, Cu, MN and SI-L can all be added to it and make the alloy, and the strength will be increased through the hot conduction. The strength of it can be comparable with the high quality alloy. The density of the pure [b]aluminum sheet [/b]is small, the density of it is near 2700kg/m3, and it is the 35%of the density of the iron. Besides, it is anti-corrosion, the surface of the aluminum and its alloy is easy to form a film on the surface, and it is the A 1203 protection film, and this protection film will be destroyed only with the strong action of the alkali ion, so it can bear the influence of the air.   what is aluminium extrusion funnel?causes and corrective actions Posted by: ZellaHyday - 07-24-2018, 07:34 AM - Forum: aluminium faq - No Replies [color=rgba(0, 0, 0, 0.75)]New topic about Aluminium extrusion die ,what is aluminium extrusion funnel?causes and corrective actions[/color] [color=rgba(0, 0, 0, 0.9)]1.What is aluminium extrusion funnel[/color] [color=rgba(0, 0, 0, 0.75)][img=720x0]https://media.licdn.com/dms/image/C5112AQGW6FrvSG-UOw/article-inline_image-shrink_400_744/0?e=2131920000&v=beta&t=BJeQfuyX2BsoQoxIQtp1lr7RrO87qMRpdzOy2F11AfQ[/img][/color] [color=rgba(0, 0, 0, 0.75)]Aluminium etrusion funnel is one special kind of defects.In the extrusion funnel it contains oxide,greasy dirt,and other defects from the billet surfaces.In the extrusion funnel part,there are cracks in the section，its mechanical property will not reach the starndards.

Although there are many kinds of anti-skid materials, the quality of stainless steel anti-skid products with stainless steel materials is well received. Crocodile mouth checkered plate groove is fixed, basic size is almost the same, because the groove is like a crocodile mouth shape, so the name of the checkered plate called crocodile mouth checkered plate, the checkered plate groove and pitch is a fixed size, center distance is the center of a hole to another with its adjacent near the distance between the nearest a hole in the center. Center distance is a way of representing the spacing of holes, and the other is the opening rate. In fact, the essence of these two expressions is the same, so when quoting or when determining the weight of the product, just confirm one of them. The arrangement of holes determines the shape composition of the surface face of anti-skid products. three bars aluminium tread plate There are many kinds of galvanized board anti-skates, such as punching hole anti-skates, crocodile mouth anti-skates, round hole anti-skates, etc. There are many kinds of materials, common aluminum plate, iron plate, stainless steel plate general thickness can be processed around 1-3mm. The most commonly used ones are stainless steel anti-skid, crocodile anti-skid, round hole anti-skid and decorative anti-skid, and surface treatment is carried out to extend the service life of the product. The anti-skid degree with hole and the anti-skid degree without hole are different for different purposes. Even if the anti-skid degree with hole is different, the anti-skid degree is different with different size of hole. The price of stainless steel antiskid is also the highest among several materials, which is its disadvantage. Advantages: stainless steel plate strength, high hardness, corrosion resistance. Therefore, in a specific environment, such as corrosion – resistant Marine skateboard, must choose stainless steel. In terms of price, there is not much difference between aluminum plate and galvanized iron plate, but the hardness is smaller than iron plate, which is its disadvantage. The advantage is shown in: on the same price, the anti-skid surface made of aluminum plate is smooth and clean without treatment, and there is no need to worry about rain and other erosion outdoors. Galvanized iron plate anti-skid, although not much different from aluminum plateanti-skid price, but the hardness is better than aluminum anti-skid. So all kinds of material anti-skateboarding has its advantages and disadvantages, according to the appropriate conditions to choose your anti-skateboarding is the most important.   trouble getting penetration in the corner of my fillet Posted by: spadekevin - 07-23-2018, 11:49 AM - Forum: Knowledge & Technique - No Replies Hello,  I have to do a certification test on 1/4 and 3/8 aluminum.

Posted by: spadekevin - 07-23-2018, 11:45 AM - Forum: aluminium faq - No Replies Hello, I've been thinking about replacing some of my old, cheap pots and pans and have been checking out some old threads on the subject. I noticed in one of the threads GwT recommended getting stuff from restaurant suppliers, so today I made the trek down and had a look. I really liked some of the stuff there, nice solid handles, held together with bolts/rivets. The only thing is that they're aluminium, is there an advantage to using aluminium over stainless steel? The other thing I noticed was that the bases weren't as thick feeling. Also, are there any problems with using aluminium cookware I should know about? Please help.  I didn't find the right solution from the internet.

Posted by: spadekevin - 07-23-2018, 11:43 AM - Forum: Knowledge & Technique - No Replies Hello, Years ago, I spent many, very many hours to polish the aluminium-parts of my 1954FL, for example the complete engine case, cam cover, transmission case, transmission cover, kicker cover, etc.I did all the polishing work myself, with the help of some dentist tools, to reach even the small nooks and hard to reach areas. The polished aluminium parts looked perfect, the engine looked like chromed, but was only polished.Then I had to store the parts in a friends garage for many years, opening the cartons was a shock to me, all the fine polished aluminium parts are "dull" today, covered with a fine white "substance"... I know about aluminium-corrosion, but the parts look like a pure horror! How to "repolish" these former high-luster polished parts, every advice from you is very welcome...? Please help. I didn't find the right solution from the internet. References: http://www.hydra-glide.com/phpBB3/viewtopic.php?t=1179 Recycle Management System Video Thank you.   What about Adidas with Cottontech? Posted by: spadekevin - 07-23-2018, 11:39 AM - Forum: aluminium faq - No Replies Hello, All of you that use anti-perspirants know the problem with them; the aluminum combines with sweat resulting in discolored and crusty shirts. Have any of you found anything that works well and doesn't stain? I know I'll have to give up the antiperspirant to avoid this problem, but hopefully I'll be ok with a little moisture. We'll see as the summer comes on. I already trim the pit hair to a moderate length and that helps reduce moisture accumulation and makes it easier to get a decent application of deodorant on.  I tried Tom's and the new 24-hour protection works ok, but the consistency of the product bugs me. It's like warm Crisco. If you dial up too much stick you can shear off a layer without pressing hard, and it leaves you wet and sticky. I suppose I could hold my arms up and wait for it to dry, but that's 5 minutes I don't want to add to the morning routine.  Anyone try Weleda or Jason stuff? What about Adidas with Cottontech? Please help. I didn't find the right solution from the internet.

Posted by: ircasodle - 07-23-2018, 06:15 AM - Forum: aluminium faq - No Replies The main alloy elements in the 6 series alloy are magnesium and silicon, with moderate strength, good corrosion resistance, weldability and good oxidation effect. It is widely used in all kinds of industrial structures with certain strength and high corrosion resistance. The main alloy elements of 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect. Whether our common seen aluminum alloy shutter door, or can, we use a lot of aluminum as raw materials. Although to average person, aluminium alloy does not have too big distinction, but if you study carefully, you can discover because of the difference of composition and making craft, aluminium alloy is very different actually. As a commonly used model, the 6061 aluminum plate is not only widely used in daily life, but also plays an important role in industry. The 6063 aluminum plate, similar to the 6061 aluminum plate, is very different because of the difference in aluminum content. As a result of the 6061 aluminum plate magnesium and silicon content is higher, it has stronger comprehensive performance, corrosion resistance and weldability, so it is often used in the aerospace field. And the processing performance of 6063 aluminum plate is also good, it is more used in some building materials engineering. For a lot of people are not quite clear the characteristic of aluminium alloy, when choose and buy aluminum sheet, they are troubled by serious price difference. Hope everybody can understand the characteristic of aluminium alloy more. First Previous Next Last
