- Q:could aluminum sheet be attracted by magnet?
- no, it couldn't.
- Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
- the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal,
aluminum sheet will directly contact hydrochloric acid, generating H2.
- Q:what's the size of gap while pressing 6mm aluminum sheet?
- choose the 8-10% of the thickness for two-sided gaps.
- Q:is there aluminum oxide on the surface of aluminum sheet after being polished by abrasive paper?
- aluminum will be oxided as aluminum oxide once being exposed in air.
- 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 is best for bonding wood and aluminum sheet together？
- cm2, leather. 4, it’s durable and can endure 106 degree high temperature.

- Q:whst should I notice while welding aluminum sheet and aluminum block?
- two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
- Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
- it may be that aluminum won't react with concentrated nitric acid.
- 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:How to polish aluminum sheet to be bright?
- as for polishing, fine grit sandpaper can't polish it into a mirror,but laser cutting can do it.
