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:What are the differences between aluminium profiles 6063 and 6463?
6063 aluminum introduction: Standard: GB/T 3191-1998, commodity name: 6063 aluminum bar, 6063 aluminum alloy bar.6063 aluminum alloy is a moderate strength heat treatment alloy in AL-Mg-Si system.
Q:Shanghai industrial aluminum profile manufacturers which is better?
How to choose the industrial aluminum profiles, this problem for the just contact with industrial aluminum profile friends, is really a serious problem to consider.That selection of industrial aluminum manufacturers is not good, money, goods is not good, he can give you redo is OK, but also take time; meet industrial aluminum manufacturers some black, and you may be wrangling, that egg pain.
Q:Brand of industrial aluminium profile
Q:Measuring 3 meters long aluminum profile line 5
For bending, twist test should be adopted according to the requirements of the platform, but in actual use, the platform used as a simple test tube can also be used to forming good Aluminum Alloy square or rectangular, note the tube before use, the first to confirm the test, can be used as a test platform.
Q:Aluminum profile powder spraying
Pretreatment -- drying, removing moisture -- spraying -- Inspection -- baking -- Inspection -- finished.1, construction requirements, general powder spraying construction requirements:(1) in order to give full play to and extend the service life of the coating, the surface of the coating is strictly treated by surface pretreatment first(2) when spraying, the coating must be completely ground to increase the spraying efficiency of the powder coating(3) to be coated with larger surface defects, it should be coated with conductive putty to ensure the smooth and smooth coating(4) after the spraying, the objects and articles should be heated, cured and solidified. The technical indexes of the powder products should be adopted, but the curing temperature and time should be guaranteed so as to avoid the quality failures caused by solidification(5) check immediately after spraying, if found defects should be timely treatment, if after curing defects are found, the only local small range without affecting, the coated surface decoration, can use the same color powder and acetone diluted to repair, if the scope is large and affects the surface quality, use sandpaper after again. Or use the paint remover to remove the coating, re Suo powder.(6) the recovered powder must be screened and removed, and then mixed with the new powder at a certain proportion(7) the powder supply barrel, the powder spraying room and the recycling system should avoid contamination by other colors. Therefore, each color change must be cleaned
Q:We look at this section of aluminum can't buy ready-made standard parts if necessary mold mold cost probably how many money?
Can do, large amount of words, mold costs borne by the manufacturers. Maybe two dies.
Q:How to prevent the aging of aluminum profile hardness is not enough?
When the time limit is guaranteed, the process is executed without overheating and time is guaranteed.
Q:Aluminum bending or curling
You can send details to my email: wangmin@bending-consult.dk offers professional adviceBending Consult is a new company with cutting-edge technology consulting. The company's sophisticated bending technology team is committed to providing professional solutions and world-class bending machine equipment for global metal profile manufacturers, and to help them create more profits.
Q:120 and 150 hidden frame glass curtain wall aluminum profile per square meter dosage, there may be curtain wall quotation cost analysis table
A window sash is glass, aluminum, metal fittings, glue, these things, aluminum, glass is accounted for the bulk
Q:What is the relationship between aluminum alloy and aluminum alloy?
Two, according to the alloy can be divided into 1024 categories: a 2011, 6063, 6061, 6082, 7075 grade aluminum alloy, which is the 6 most common. Grades are different in various metal components ratio is not the same, in addition to the commonly used aluminum doors and windows In addition to such as the 60 series, 70 series, 80 series, 90 series, curtain wall series aluminum profile, aluminum industry has no clear distinction model, most manufacturers are in accordance with the actual drawings processing customer. Three, according to the requirement of surface treatment: 1. anodized aluminum 2. Electrocoat aluminum 3. aluminum powder coating 4. transfer grain aluminum 5. aluminum polishing (divided into mechanical polishing and chemical polishing of two, the chemical polishing of the highest cost, the price is the most expensive)
