Aluminium is a relatively soft,durable, lightweight, ductile and malleablemetalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (asmuch as 98%) of medium and far infrared radiation. The yield strengthof pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel.It is easily machined, cast, drawn and extruded.
Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

- Q:How much cube is the 0.9mm aluminum rolling?
- This is a common problem. Anyone who had received high school education can calculate it very quickily. One way is to calculate sectional area with circular area, then times the thickness of the aluminum rolling. Another way is to use the outer diameter circular area to subtract the core area and then times the thickness of aluminum rolling.
- Q:I have been reading up on thermite and the required ingredients. I have extremely fine aluminum powder from a small etch-a-sketch sitting on plastic wrap in my room. On the comments page of the site i got the thermite ingredients from, multiple people said that thermite could explose if you use too fine of a powder. I have also read that powdered aluminum can become very explosive when it is exposed to air or if it becomes damp. Ive gotten particulary worried because the humidity right now is 93%. So, is powdered aluminum too dangerous to have in house and is too fine powdered aluminum explosive when in thermite?
- Powdered aluminium isn't explosive, and any humidity or dampness in the air won't affect it. Really finely powedered aluminium is nothing but an extremely powerful reducing agent. In other words, it won't explode, but it will burn very fast and very hot. When combined with magnesium powder, it contributes to the nature of thermite in a reduction-oxidation reaction. On it's own however, as long as you keep it away from any open flames, it's perfectly safe. I should say; be very, very careful with making thermite. It's not explosive on it's own, but if you make it wrong, it can fizzle and pop and send molten metal flying your way.
- Q:Are aluminum coils fire-resistant?
- Aluminum coils possess fire-resistant qualities due to their high melting point of 660 degrees Celsius (1220 degrees Fahrenheit) and their inability to burn, rendering them non-combustible. This specific characteristic allows for the utilization of aluminum coils in various applications, particularly in sectors where fire resistance is of utmost importance, such as building construction, electrical wiring, and HVAC systems. Moreover, the remarkable heat conductivity of aluminum facilitates rapid heat dissipation, thereby minimizing the risk of fire incidents. Nevertheless, it is crucial to acknowledge that although aluminum coils themselves exhibit fire-resistant properties, they may be incorporated into systems alongside other components that might not share the same level of fire resistance. Consequently, it is essential to consider the entirety of the system and adhere to proper fire safety regulations and guidelines to ensure comprehensive fire safety precautions.
- Q:How do aluminum coils contribute to sustainable packaging?
- Aluminum coils contribute to sustainable packaging by offering several key benefits. Firstly, aluminum is a highly recyclable material, which means that aluminum coils can be easily and efficiently recycled, reducing the need for new raw materials. Additionally, aluminum is lightweight yet strong, allowing for more efficient transportation and reducing carbon emissions during shipping. Furthermore, aluminum has excellent barrier properties, protecting products from light, moisture, and oxygen, thus extending their shelf life and reducing food waste. Lastly, aluminum packaging can be easily resealed, promoting reuse and reducing the consumption of single-use packaging. Overall, aluminum coils play a crucial role in sustainable packaging practices by promoting recycling, minimizing waste, and reducing environmental impact.
- Q:How are aluminum coils processed to achieve desired mechanical properties?
- Aluminum coils are processed to achieve desired mechanical properties through a combination of cold rolling, annealing, and heat treatment. Cold rolling reduces the thickness of the aluminum coil, increasing its strength and hardness. Annealing, a heat treatment process, is then applied to soften the material and improve its formability. Additional heat treatments may be conducted to further enhance mechanical properties, such as tempering to increase toughness or solution heat treatment to improve strength and corrosion resistance. These processing techniques allow manufacturers to tailor the mechanical properties of aluminum coils to meet specific application requirements.
- Q:I heared the aluminum weakens or melts.
- Mercury readily combines with aluminium to form a mercury-aluminum amalgam when the two pure metals come into contact. However, when the amalgam is exposed to air, the aluminium oxidizes, leaving behind mercury. The oxide flakes away, exposing more mercury amalgam, which repeats the process. This process continues until the supply of amalgam is exhausted, and since it releases mercury, a small amount of mercury can “eat through” a large amount of aluminium over time, by progressively forming amalgam and relinquishing the aluminium as oxide. Aluminium in air is normally protected by a thin layer of its own oxide, which is not porous to mercury. Mercury coming into contact with this oxide does no harm. However, if any elemental aluminium is exposed (even by a recent scratch), the mercury may combine with it, starting the process described above, and potentially damaging a large part of the aluminium before it finally ends.
- Q:I am so confused right know. I want to cook something using an aluminium foil. Is the reflective side supposed to be inside or outside?
- As everyone who's answered has already told you, Saran Wrap is clear plastic. It's used to wrap left-overs and sandwiches in...although it's not totally air-tight, it comes close to it. Aluminum foil is used to cover things while you're baking or roasting them (like a turkey breast or lasagna) or it can be used on the bottom of a cookie sheet or oven rack to catch spills. It helps to radiate heat. You can also use aluminum foil to wrap things in for refrigeration. It just doesn't create the seal that Saran Wrap does.
- Q:What is the typical thermal conductivity of aluminum coils?
- Aluminum coils typically exhibit a thermal conductivity ranging from 205 to 220 W/mK. Renowned for its exceptional thermal conductivity, aluminum stands as a favored option for heat transfer purposes, notably within HVAC systems, refrigeration units, and heat exchangers. The remarkable thermal conductivity of aluminum facilitates effective dissipation and transfer of heat, thereby guaranteeing peak performance and energy efficiency in said systems.
- Q:What is the typical lifespan of an aluminum coil?
- The typical lifespan of an aluminum coil can vary depending on factors such as usage, maintenance, and environmental conditions. However, with proper care and regular maintenance, an aluminum coil can last anywhere from 20 to 30 years or even longer. This lifespan can be extended by keeping the coil clean, ensuring proper ventilation to prevent moisture buildup, and addressing any damages or issues promptly. Additionally, factors such as exposure to harsh weather conditions, chemicals, or corrosive environments can impact the lifespan of an aluminum coil. It is important to consult with manufacturers or industry professionals for specific information regarding the expected lifespan of a particular aluminum coil in different applications.

- 1) Do you recycle aluminum (soda cans, etc.)? Yes, as much as possible. 2) Why do or don't you recycle aluminum? I recycle cans so the material can be reused in new products and applications. 3) Does it make a difference to the economy whether we recycle or not? Yes, it provides jobs and increases the availability of green materials which have been popular for a number of years. 4) Does it make a difference to the environment whether we recycle or not? Yes, aluminum leeching into the earth via landfill or other trash is not good. 5) What do you think would help people to recycle more? Such as a reward, information, resources, etc. Make it cool and popular to recycle. Recycling is far more prevalent now than it was 20 years ago when I started doing so on a regular basis.
