Q:What does 1060 stand for in 1060 aluminum rolling?
It means the aluminum content should be above 99.6%.
Q:What are the compositions of aluminum coil coating?
Resin, pigment, auxiliary and solvent.
Q:How to identify the quality of color coated aluminum coil and sheet?
Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
Q:How much is the 25mm aluminum coil at current market?
You must mean 25-wide aluminum coil. The price consists of the aluminum ingot price and processing charges. For example, if the processing price is 4500 yuan, it is relatively cheap. 25mm-wide aluminum coil is very narrow, so it will be much complicated to strip.
Q:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:Why do the layers loose when taking out coil after roll of aluminum 0.14?
After rolling, the most possible reason may be poor deoiling effect. I think, for 0.14mm aluminum coil, the lining sleeve will not be forgotten. After rolling , oil ooze from aluminum layers, and the support of aluminum coil is not enough, leading to coil collapsing. The specific manifestations are that the edges of even round aluminum layers become like water ripple, and that the aluminum coils suddenly become uneven when taking out coil.
Q:Which companies will use aluminum sheet and coil?
Plants to make auto parts such as exhaust pipe thermal baffle, muffler thermal baffle and front thermal baffle.
Q:What are the best rust-proof coils? Please tell me the model and manufacturer in Shangdong. Thank you.
3003 aluminum coil, AL-Mn series alloy, is the most widely used rust-proof aluminum with the density being 2.73. It is applicable to insulation projects such as pipe insulation, packaging, machine parts, refrigerator, air conditioning and ventilation pipes and other wet environment.
Q:How to calculate the length of aluminum sheet with the thickness known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width). Ps: Keep unit the same.
