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 nitridings
What does "3030W" W mean for European standard industrial aluminum?
- This refers to the 3030 heavy aluminum profiles. General aluminum profile manufacturers will make a number of their own products, European standard 3030 series has a variety of specifications, such as Jing Teng aluminum European standard 3030R, referring to the European standard 3030 fan, 3030G refers to the 3030 GB profiles. In short, look at your own needs,s
What are the aluminum profile markets in Cangzhou, Renqiu?
- Aluminum market, located in Renqiu city in Yi Zhen Zhang Liu Zhuang industrial area, if you find a direct about Liu Zhuang industrial zone can be. Known as the North's largest aluminum production base, I look not so goods
Chengdu where to sell aluminum profiles of many businesses?
- Today I went to Qingbaijiang Fengxiang profile market. Where is the place where the aluminum alloy merchants gathered, the profiles, accessories, processing?...... Goods are available in all varieties。 But the aluminum doors and windows only home balcony with the majority, profile industry, such as steel rack chassis radiator with basically No. This market sells stainless steel materials, businesses are also more.s
Regarding the wall thickness of aluminum alloy profiles, are there any standards in the country?
- < technical specification for glass curtain wall JGJ102-2003> open section bar is not less than 3.0mm. For example, the beams are mostly open and closed at one end with a cover plate. Closed profiles such as stand up, mostly closed type, not less than 2.5mm, these are only the minimum requirements for wall thickness, but also in accordance with the calculation of the book in the calculation of the wall thickness.s
Two kinds of industrial aluminum profiles 5050 8mm slot width and slot width 10 mm,
- There must be a difference. There is a distinction between rice weight and wall thickness. For example, Jing Teng Aluminum CompanyJT-8-5050W meters weight is 3.25KG,,JT-10-5050 meters weight is 2.95KG. Specific parameters, you can go to consult the next businesss
How are the aluminum and aluminum sections joined?
- Bonding is not only applicable to homogeneous materials, but also to dissimilar materials. Bonding process is simple, and no complicated process equipment is needed. Bonding operation is not necessary under high temperature and high pressure. Therefore, the adhesive parts are difficult to deform and the stress distribution of the joints is even. Under normal circumstances, the adhesive joint has good sealing, electrical insulation and corrosion resistance.Other mechanical connections, such as fasteners, connections, riveting, etc..s
