FAQ

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 answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.

I need to coat a piece of aluminum with aluminum oxide. Can I do it by just attaching aluminum to an electrode and put it into some water with the other electrode? I know you can make iron oxide that way, but will aluminum work? If it will work, which electrode should I put the aluminum on?

The way I remember it is a cathode is like a catheter because they both receive stuff and the anode is the opposite of that) So, if you break apart Al2O3 you have 2Al^3+ and 3O^2-. Al^3+ goes to the cathode to receive electrons and become a neutral metal. O^2- goes to the anode to donate electrons and become O2 gas. Hope the analogy and explanation helps!

Yes, 101 aluminum sheets are suitable for food-grade applications. 101 aluminum is a commercially pure alloy with excellent corrosion resistance and good formability. It has a low chemical reactivity, which means it does not react with acidic or alkaline foods, making it safe for use in food-grade applications. Additionally, 101 aluminum sheets can be easily cleaned and sanitized, making them an ideal choice for food processing, packaging, and storage.

Can someone please explained what aluminum reacts slowly with dilute acided?Thank you!

Firstly, dilute acids are weaker than concentrated acids. This slows the rate of reaction. Secondly, Aluminium is less reactive than the Group 1 and Group 2 metals, which slows the rate of reaction. It is less reactive because it has to form 3+ ions which is more draining than forming 1+ or 2+ ions. Thirdly, Aluminium oxidises well in air but, unlike rust, this oxide sticks to the pure aluminium, forming a protective layer.

When it comes to conductivity, aluminum sheets and copper sheets have their differences. Copper is known for its exceptional ability to conduct electricity and is considered one of the most conductive metals available. Its high electrical conductivity allows electricity to flow through it with minimal resistance. On the other hand, aluminum, while still a good conductor of electricity, is not as conductive as copper. In fact, aluminum has about 61% of the conductivity that copper possesses. As a result, if high conductivity is a top priority, copper sheets would be the preferred option. However, if cost-effectiveness and lightweight properties are more important, aluminum sheets can still offer adequate conductivity for many applications. Ultimately, the decision between aluminum and copper sheets relies on the specific project requirements and the balance between conductivity, cost, and other factors.

The fire rating of 101 aluminum sheets is typically classified as Class A, indicating a high level of fire resistance.

Indeed, water storage applications can make use of aluminum sheets. Aluminum, being a lightweight and resilient substance, exhibits remarkable resistance towards rust and corrosion. Moreover, it possesses impermeability to water, air, and light, thereby rendering it an optimal selection for water storage. Furthermore, aluminum sheets can effortlessly be molded into diverse dimensions and configurations, enabling the creation of personalized water storage solutions.

What is the difference between aluminum sheet and aluminum curtain wall? The cost is high!

Composite aluminum plate is also called aluminum composite plate,The aluminum composite plate and aluminum sheet belong to curtain wall decoration materialThe difference between the two liesThe aluminum sheet is also called the pure aluminum sheet, and the single aluminum plate is coated with decorative paint on the aluminum plate surface,Aluminum composite plate is two layers of relatively thin and some also coated with aluminum decorative paint, and a middle plastic or honeycomb core, corrugated core, fireproof core plate composite. Contains aluminium composite panel, aluminum honeycomb board, aluminum composite corrugated board, aluminum composite wood plate, aluminum plate with the stone composite.According to the raw material composition, the aluminum single board price will be higher
