Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).

Q:How is aluminum profile storage
5, stamp, pay attention to heavy material placed in the following, light material and variable material on the top, decorative surface as far as possible without bearing.
Q:What is the thickness of the aluminum alloy window frame?
According to the GB / T5237 Aluminum Alloy "building materials" regulations, construction aluminum minimum nominal wall thickness should be not less than 1.2mm, wherein the solid profile wall thickness error of 0.15mm, namely the wall thickness not less than 1.05mm; hollow profile parts containing a closed cavity wall thickness allowance of 0.23mm, the wall thickness is not lower than 0.97mm.
Q:Can aluminum profiles be extruded into hollow profiles?
Of course you can. But it depends on what brand and specific specifications you use
Q:Why should aluminum surface treatment process?
The hard oxide film formed after the surface oxidation treatment prevents the internal aluminum from being oxidized and prolongs the service life of the aluminum profile.
Q:Where can I buy the aluminum profile information?
Can go to the Alibaba website, China aluminum network, HC network, China manufacturing network, Mark Polo network, business treasureGlobal hardware networkMusic for hundredChinese supplierChalcoChinese aluminum netGlobal economic and trade networkWeb sites such as the world trade network will be fine,
Q:The latest list of aluminum China
The first aluminum aluminum (China Aluminum Group, the central management of large state-owned enterprises)Second of Asia Aluminum (Asia Aluminum Group, Asia's largest aluminum producer, Chinese brand)Third strong aluminum products (China famous brand, national inspection free products)Fourth (Chinese Fenglv aluminum material brand, national Mianjian products)Fifth Zhong Zhong aluminum (China famous brand, China well-known trademark, national inspection free products)Sixth (Chinese Hing Fat aluminum brand, A Well-Known Trademark in China, national Mianjian products)Seventh South Asia Aluminum profiles (China famous brand, national inspection free products)Eighth Nanshan aluminum (China famous brand, China well-known trademark, national inspection free products)Ninth by court aluminum profiles (China well-known trademarks, national inspection free products)Albert tenth aluminum (China famous brand, national inspection free products)
Q:Chengdu has several building materials markets for aluminium extrusions?
512 building materials market 'The two ring road north station over there direction
Q:The aluminum and Fenglv aluminum material which is better suited for doors and windows
Al Feng is one of the ten famous material, certainly no problem. But Feng packaging is too thick, high cost. To do the doors and windows of the aluminum used to choose cost-effective, as a special material for the sale of aluminum, I have the following recommendations: 1. The window wheel is good, and the pressed glass should be durable and corrosion resistant. 2. doors and windows sealing performance better, 3. pages to be matched with materials, gauze or rust, and thickness and density better than 4. The cost performance is high, the surface treatment layer of the profile is electrophoresis, and the electrophoresis layer should be thick. 5. The mounting frame needs to be hit to the horizontal line.
Q:80 series insulation aluminum broken bridge 1.4 thick, one square kilogram, how many kilograms aluminum material?
Each brand of profiles, aluminum weight is not the same, but within the unit area is about 8 kilograms, little difference
Q:How to distinguish the good or bad of aluminum profile simply?
With customers in the process of aluminum found billion purchase of aluminum profile, most do not know how to see the quality of aluminum profiles. And sometimes, many users in order to save costs, and select some cheaper industrial aluminum to do the work table stent, resulting in not long after the emergence of cracking, fading situation.
