Q:how to process 0.3mm hole on aluminum material?
punching wire-electrode cutting
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:does aluminum sheet has a function of magnetism isolating?
yes.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
You can sprinkle the mix of Alkaline water,vinegar,washing powder and liquid detergent on the surface. And after a period of time, rub it with soft silk, after it being dry,sprinkle again and rub until it's clean.
Q:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
you can use deburring brush,grinding fluid,abrasive powder and other consumables.
Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
It’s possible, there are several problems: 1, workers won’t wipe it thoroughly and fully, so you can wipe it after soaking. 2, the wiping efficiency is low, and we can use ultrasonic to clean it. 3, the water is poisonous and harmful to environment and workers’ health, so you can use water base to clean it, environmental and non-poisonous. Of course, if you really want to change, you can use detergent special for aluminum materials cleaning of our company, Changlvfeng chemical industry company. a, its PH value is 6.8-7.2 and it is totally an neutral liquid. b, good material applicability, detergent invented for aluminum materials. c, good degreasing ability, it has a good degreasing function for various oil contamination in processing and has no effect on material.
Q:How to distinguish aluminum sheet from magnesium sheet?
put them into acid and observe bubble's generating speed, the quicker one is magnesium sheet.
