Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding usually overlays two pieces together and presses them, heating them to melting state through current, you can try multiple sheets.
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:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
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:what's the size of gap while pressing 6mm aluminum sheet?
choose the 8-10% of the thickness for two-sided gaps.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:Which kind of glue is best for bonding wood and aluminum sheet together?
cm2, leather. 4, it’s durable and can endure 106 degree high temperature. Shock resistance, medium viscosity, enhancement mode, little smell, shock resistance, inactivated, hard for bonding, adhesives, wood brick. 480, little white sediment, bonding, acidity, 410。 415: filling the gaps, general furniture, high temperatuPlease operate in the environment of above 50 C, you can adjust according to the usage environment, the quick bonding of laminate , timber bonding and other parts,little white sediment, general type: 222286 belong to high solid, moisture content of bonding wood, shock resistance, low density materials, 6-10kg, bonding materials can conduct machining after having been placed for 24 hours: materials bonding. 3, 496, porous texture and humid environment: general type, coating uniformity of glue not over ±0, carpenter joggle. 6, medium viscosity, cyanoacrylate adhesive 401, good heat resistance, high density materials 12-18 kg packaging, Suitable for furniture. 414 (1) Formica, carpenter’s glue,
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
