FAQ

Aluminum sheet is made through a process called rolling, where a large aluminum ingot is passed through a series of rollers that gradually reduce the thickness of the metal until it reaches the desired sheet thickness. This process helps to improve the strength, flexibility, and surface finish of the aluminum sheet.

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.

(2) when aluminium foil is dipped in mercury for a short time and then placed in water a reaction is seen to occur with hydrogen gas being one of the products.?????

Aluminium is very reactive in air and forms a protective oxide coating. This protects it when placed in water as aluminium oxide is unreactive with water. When immersed in mercury the oxide coating is removed and therefore the aluminium itself reacts when the cleaned aluminium metal is immersed in water.

How much is the aluminum plate with a thick 2mm 1000*2000? Thanks

(the current price of aluminum ingot is about: 15000 yuan / ton, plus board processing fee 2000/ tons, =18000 yuan / ton), the proportion of 2.71*3mm* aluminum plate price 18 yuan / kg, =146.34 yuan / square. 2MM*2.71* price 18 yuan =97.26 yuan / square.

Yes, aluminum sheets can be anodized to significantly improve their hardness. Anodizing is an electrochemical process that thickens the natural oxide layer on the surface of the aluminum, creating a durable and corrosion-resistant coating. This process enhances the hardness and durability of the aluminum sheets, making them more resistant to wear, scratches, and other forms of damage.

The yield strength of aluminum sheets may differ due to several factors, including the aluminum alloy, the tempering process, and the sheet thickness. Typically, aluminum sheets exhibit a yield strength that falls within the range of 10,000 psi (69 MPa) to 45,000 psi (310 MPa). Nonetheless, it is crucial to acknowledge that these values are only estimates and can fluctuate depending on the precise grade and temper of the aluminum in question.

Yes, aluminum sheets can be used for industrial shelving. Aluminum is a lightweight and durable material that is resistant to corrosion, making it suitable for various industrial applications, including shelving. It offers strength and stability while being easy to clean and maintain. Additionally, aluminum's versatility allows for customization and modification to fit specific storage needs.

Outdoor signage can indeed be made from 101 aluminum sheets, which possess the necessary qualities for such purposes. Aluminum is renowned for its ability to endure and resist weathering, rendering it a perfect material for outdoor applications. The 101 aluminum alloy, in particular, has been crafted to possess exceptional strength and resistance against corrosion, making it even more suitable for outdoor signage. It can withstand harsh weather conditions, including rain, snow, UV exposure, and temperature fluctuations, without succumbing to corrosion or deterioration. Moreover, aluminum sheets are lightweight, facilitating their installation and transportation. All in all, 101 aluminum sheets offer a dependable and enduring solution for outdoor signage.
