- Q:how to separate the aluminum sheet in plastic?
- Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
- Q:which kind of aluminum sheet could be bended after being etched?
- general etching materials include stainless steel and copper.
- Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
- physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
- 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:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
- You can buy the glue for bonding wood in hardware shop, 402 or 502 are all ok.
- Q:what's the size of aluminum sheet circle?
- aluminum sheet circle's texture 1060, 3003 thickness 0.4-5.0mm, diameter 190-760mm.
- Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
- 1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
- Q:as for heating coil and aluminum sheet, which one is better for heating?
- Heating coil has a short lifetime, and aluminum sheet for heating can be used for a long time. Stainless steel heating tube is embedded into aluminum sheet for heating, because the heating coil isn’t exposed, it can be used for a long time.
- Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
- Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
- Q:Could two pieces of aluminum sheets be welded together?
- Sure, two pieces of alumminum sheets can be welded together, but which kind of welding method you choose is the key point.
