Q:Top 10 ranking enterprises of aluminum profiles in China
Don't just look at rankings, which is something false, we all know in the aluminum industry, aluminum extrusion and some more than 50 units, annual production capacity of 90 thousand tons, were stronger than some ten enterprises inside the above you can see, but in the rankings but no, this ranking is water.
Q:How does the aluminum profile bevel come round?
If the stitching aluminum alloy model is the same, then the cutting angle must be 45 degrees, it is possible to splice.You can try it yourself and make a small tool to fix this angle in advance.
Q:5002 and 6063 aluminum profiles difference
6063 aluminum alloy main alloy elements for magnesium and silicon, with excellent processability, excellent weldability, extrusion and electroplating, good corrosion resistance, toughness, easy polishing, coating, anode oxidation effect is excellentIt is a typical extrusion alloy, widely used in building profiles, irrigation pipes, tubes, rods and profiles for vehicles, platforms, furniture, elevators, fences, etc.
Q:Where is the aluminum profile market in Nanjing? Specific address, bus route
Before inadvertently arrived, as if on the South Fengtai Road, and now do not know where.
Q:How to design the extrusion die for aluminum extrusion? Ten
1, to let them die factory processing, mold design they figure, their wages are high, so I want to learn, do not know where to start, buy a book, the mold design of aluminum extrusion, want to learn to know the properties of extrusion machine, structure;2, according to the experience, to a step by step to produce aluminum profile extrusion die to meet the size requirements, first of all to ensure the uniformity of metal flow and extrusion out of the heart often Youao phenomenon, cause the surface subsidence, the flatness is not standard, through a lot of practice conclusion.
Q:What is the nitriding process of aluminum extrusion die?
The principle of nitridation:Gas nitrocarburizing, that is gas nitrocarburizing, refers to low temperature nitrocarburizing based on gas nitriding and carburizing. Commonly used media have 50% ammonia, +50% endothermic gas (Nitemper method); 35%-50% ammonia, +50-60% exothermic gas (Nitroc method) and ammonia through the drip ethanol or formamide and so on. In soft nitriding, because of the high solubility of carbon atoms in the epsilon phase, the soft nitrided surface is a common compound of carbon and nitrogen, which is good in toughness and wear resistant.In the process of gas nitrocarburizing, due to the extremely low solubility of carbon atoms, it quickly reaches saturation state and precipitates many super micro cementite points. These cementite particles, as the core of the crystallization of nitrides, contribute to the formation of nitrides. When the surface nitrogen concentration reaches a certain level, the epsilon phase is formed, while the carbon solubility of the epsilon phase is very high, which in turn accelerates the dissolution of carbon.After gas nitrocarburizing, its structure is composed of epsilon phase, gamma phase and nitrogen containing cementite Fe3 (C, N), carbon will reduce the diffusion rate of nitrogen, so the thermal stress and the stress of the tissue are hard, the nitriding is large and the layer is thinner. But at the same time, because the soft nitride layer does not exist. Therefore, the nitride layer, better toughness than hard nitriding
Q:Shanghai industrial aluminum profile manufacturers which is better?
For the choice of aluminum profiles, here are a few suggestions for you to refer to:First: very cheap, do not chooseAs follows: the cost of industrial aluminum material = the spot price of aluminum ingot, the processing cost of extrusion aluminum material, the freight of packing material. These are transparent, the cost of aluminum profiles are similar, significantly lower than the market price, the first possibility: the weight per meter less; second: aluminum is the use of recycled materials; third: material loss amplification (not according to the actual sales amount of meters).Second: only understand the sale material supplier does not chooseExplain as follows: preparing goods, recruit a few operator, big online promotion can be opened. Those who are often hurt are our buyers. Miss wiring mostly do not know how to use, only know the unit price. How to use to meet customer needs; how to make the most cost-effective; in different venues that kind of connection is the best; these are they can not answer accurately. Only know the cheapest and recommended profile connection the cheapest; this connection is the lowest cost, but the cost of artificial, a connection is the weakest, aluminum convenience wouldn't be reflected, and will bring much trouble for the future reconstruction. But the wiring girl will push it one way.
Q:Industrial aluminum profiles are generally used in what industry?
Kunshan Austrian crown aluminum to tell you: mainly used in the manufacture of industrial production, such as automation equipment, covering the skeleton and the custom mold machinery and equipment according to their own requirements, such as assembly line conveyor belt, hoisting machine, glue machine, testing equipment, shelves and so on, electronic machinery industry and clean room with.
Q:How to distinguish the true and false of aluminum profile
Al Feng brand aluminum precision identification method is to do chemical detection. But in the absence of our conditions, we can only use "observation" to distinguish. What is "observation method", that is, we make a different perspective on the surface of aluminum. Aluminum door and window section is made of aluminum rod by die extrusion and the like, fake phoenix aluminum using bauxite as raw material, so the material contains a lot of impurities, extrusion is easy to mold galling, the surface profile produced is not smooth, there are many marks, and profiles of scrap produced. Can not be reached in a variety of physical effects on strength and hardness.The surface treatment of fake profiles for powder coating (common color: green, white, grey), said simply in this way, the profile above is squeezed out of the powder coverage, this method has great advantage on fake garbage can be squeezed out of aluminum profiles, profiles on the marks effectively cover. But because of fraud for more cost savings, they use inferior adhesion powder, short life, easy to fall off, and covered in the profile of the powder also small and thin, and extruded profile marks are too deep, even if there is a cover up the layer of powder, as long as viewed from different angles and shapes position still, it is easy to see these ugly marks.
Q:How is the aluminum alloy profile series divided?
According to alloy composition.1 pure aluminum, such as 1100,2 series aluminum alloy3 Series al Mn alloys, such as 3003, 3A214 series Al Si alloy5 Series Al Mg alloy6 series Al Mg Si alloy, such as 606360617 Series Al Zn Alloy8 lines, others9 line standby
