Q:I want to make a part using molten aluminum with a hole through the middle and would like to use a steel rod to do this. Would the bar stick to the aluminum when it cools and not be able to be removed? If so is there so type of coating I can use so it can be removed?

Aluminium and iron are pretty incompatible materials, they don't form an alloy I don't think, so it is unlikely they would stick. Also, both metals will get an oxide layer on the surface which should keep them separate. Try it! If the finished part does stick, try heating the aluminium then dip the steel rod in some ice water.

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:... initial temperature of the water or the initial temperature of the aluminum? Why?

Let's say the aluminum starts out at a higher temperature than the water. The aluminum cools down by 1°C, which means it loses energy (Q = mcΔT, where ΔT = 1°C). That energy goes to the water, warming it up. Since Q is the same for both water and aluminum, and m is the same for both, all that matters is the heat capacity c. Water has a higher heat capacity than aluminum, so for the same Q it must have a smaller ΔT. This process continues until both have reached the same T. From the above paragraph, you should be able to figure out if the final T is closer to the initial water temp or the original aluminum temp.

Q:Are aluminum sheets suitable for aerospace wing structures?

Yes, aluminum sheets are suitable for aerospace wing structures. Aluminum is widely used in the aerospace industry due to its excellent strength-to-weight ratio, corrosion resistance, and its ability to withstand high temperatures. Aluminum alloys, such as 2024 and 7075, are commonly used for wing structures as they provide high strength and durability. Additionally, aluminum can be easily formed into different shapes and sizes, allowing for the production of complex wing designs. Overall, aluminum sheets offer a combination of lightweight properties, strength, and reliability, making them highly suitable for aerospace wing structures.

Q:How does aluminum sheet compare to other metals in terms of weight?

Aluminum sheet is exceptionally lightweight compared to most other metals. It has a lower density, making it a popular choice for applications where weight reduction is a priority.

Q:What are the different types of surface treatments available for aluminum sheets?

There are several different types of surface treatments available for aluminum sheets, each serving a specific purpose and providing unique characteristics. Some of the most common surface treatments for aluminum sheets include anodizing, painting, powder coating, and polishing. Anodizing is a process that involves the formation of a thick oxide layer on the surface of the aluminum sheet. This treatment not only enhances the appearance of the sheet by providing a variety of colors, but also improves its corrosion resistance and durability. Anodized aluminum sheets are widely used in architectural applications, automotive parts, and electronics. Painting is another popular surface treatment for aluminum sheets. It involves applying a layer of paint on the surface to enhance its appearance and provide additional protection against corrosion and wear. Painted aluminum sheets are commonly used in signage, building facades, and decorative applications. Powder coating is a type of surface treatment that involves applying a dry powder to the aluminum sheet and then heating it to create a protective layer. This treatment offers excellent durability, resistance to weathering, and a wide range of color options. Powder coated aluminum sheets are commonly used in the construction industry, as well as for automotive parts and appliances. Polishing is a surface treatment that involves buffing the aluminum sheet to create a smooth and reflective surface. This treatment enhances the aesthetics of the sheet, making it ideal for decorative applications such as furniture, jewelry, and architectural accents. Overall, the choice of surface treatment for aluminum sheets depends on the desired appearance, functionality, and application requirements. Each treatment offers unique benefits and characteristics, allowing for versatility and customization in various industries.

Q:Are 101 aluminum sheets suitable for food packaging?

Yes, 101 aluminum sheets are suitable for food packaging. Aluminum is widely used in the food packaging industry due to its excellent properties. It is lightweight, durable, and resistant to corrosion, making it an ideal material for preserving the freshness and quality of food products. Additionally, aluminum is a good barrier against light, moisture, and oxygen, which helps to extend the shelf life of packaged food items. Therefore, 101 aluminum sheets are a suitable choice for food packaging applications.

Q:Can aluminum sheets be stamped or pressed?

Yes, aluminum sheets can be stamped or pressed.

Q:I have to wire solar DC photovoltaic panels and have always used at least an 8 gauge wire. Recently, I installed a solar electric fence and they recommended special electric fence wire that can handle 10,000 volts. It looks aluminum. The fence techs told me copper is only rated for 600 volts. And the power will leak through the insulation. They also say copper will corrode and created insulated spots. Does this mean that aluminum doesn't corrode and is it superior to copper? Is is all a lobbying scam to force us to buy copper? Can I use the electric fence wire in my solar wiring?

Why in the name of G-d are solar panel installations using higher than 600 volts? I can't imagine the clearances in the panels will stand 10,000 volts without jumping arcs. It is true that the rubber insulation used on most wiring is rated at 600 volts breakdown - special neon rated wire is used for higher voltages, which can also be copper. When you say electric fence wire, you actually mean the short wires that run from the high voltage source to the end of the bare wires which are usually steel to withstand the force of animals who bump into them before the shock drives them off and which is the wire most of us think of as fence wire. There is a problem using aluminum wire, especially in houses, because it forms a hard oxide surface very quickly and expands and contracts more than copper, so it must be used with special connectors that break through the layer and grease that keeps off the air. If you are using 8 gauge wire, you are doing it because of fairly high amps, which usually involves low voltages and solar arrays I have looked into have been 12, 24 and 48 volts. If your system is putting out 30-40 amps at 600 volts, you are 18,000 watts or more through 1 set of wires. Really? Or am I mixing two systems?
