Q:What does 1060 stand for in 1060 aluminum rolling?
It means the aluminum content should be above 99.6%.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:What is the common color of aluminum coil membrane?
The blue transparent membrane is the most common.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:Why does the coated aluminum coil have thickness requirement for membrane?
The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
Q:How to deal with too much aluminum powder in aluminum striping?
Currently, there are bag dust-removal system and water dust-removal system. The former is very popular with enterprises because of low maintenance cost, accounting for over 90%. But the problem is the dust accumulation because the ventilation and dust removal systems are not produced in strict accordance with the standard. For example, controlling wind speed does not meet the requirement; ventilation and dust removal system does not meet the requirements of explosion-proof, including the set of pipes, series and parallel connection, the choice of dust removal system, the spark detection and extinguishing measures.
Q:Why the aluminum sheet crack after?
What I want to add is to choose such welding wires as 5383 or 5183 wire whose magnesium content is higher than 5754 wire. The loss of magnesium due to high temperature in welding process may reduce the intensity of welding area.
Q:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
Q:Why the aluminum-plastic panel processed by color aluminum coil peel off paint?
It may be due to the bad quality of the color aluminum coil paint or the poor paint-drying process.
