- Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
- The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
- Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
- Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
- Q:how to connect copper pipe and aluminum sheet?
- it depends on the size and requirement, we can use ultrasonic wave rolling welding to connect copper pipe and aluminum sheet.for example, solar energy radiator-fan contains connection of copper pipe and copper sheet, ultrasonic wave rolling welding equipment is used here.ultrasonic wave welding of metals is suitable for the welding of copper to copper, copper to aluminum and aluminum to aluminum.
- Q:which kind of aluminum sheet could be bended after being etched?
- general etching materials include stainless steel and copper.
- 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:Which kind of glue can bond two pieces of aluminum sheets?
- you can use jellied universal glue, don't use the liquid one, because it's only suitable for plastics or materials easy for erosion.
- Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
- no problem.
- Q:what's the temperature tolerance of aluminum sheets?
- aluminum is a kind of silver white metal,melting point:660.4℃, boiling point: 2467℃,density: 2.70 g/cm³,very light, about 1/4 of iron's density.it has low hardness and good ductility, which makes it suitable for being pulled into threadlets or pressed into aluminum foils, and the later is usually used for packaging candy and cigarette. it has good electrical and temperature conductivity. it's used for the manufacture of electric wire and cable in electric power industry, and for the manufacture of cooker in daily life.combined with the magnesium , copper,zinc,tin,manganese,chromium,zirconium,silicon and other elments,it can formulate various alloys that is broadly used for the manufacture of airplane,car,ship, materials of daily living equipment and the doors and windows of construction industry.aluminum is one of the best reflectors of heat and light, so it is used as thermal insulation material and the manufacture of reflecting mirror in the reflecting telescope.
- Q:could aluminum sheet be attracted by magnet?
- no, it couldn't.
- Q:how to process 0.3mm hole on aluminum material?
- punching wire-electrode cutting
