FAQ

Aluminum coils are formed into different shapes and profiles through a process known as aluminum coil slitting and forming. This involves passing the coil through a series of rollers and dies that apply pressure and force to shape the metal into the desired form. The specific shape and profile are determined by the design of the rollers and dies used in the process.

can you use the Brasso Aluminum cleaner on aluminum wheels? i have a set of mickey thompson classic II wheels and i want to polish them up. they have water spots that are almost impossible to clean. how can i shine them up to make them almost like chrome wheels? i heard brasso works great but then i heard it damages the wheels?

Brasso On Aluminum

There are several different alloy grades used in aluminum coils, each with their own unique properties and applications. Some of the most commonly used alloy grades include: 1. 1100: This is a commercially pure aluminum grade, known for its excellent corrosion resistance and high thermal conductivity. It is often used in applications that require good formability, such as fin stock, heat exchangers, and chemical equipment. 2. 3003: This alloy grade is known for its moderate strength and good workability. It is commonly used in applications that require both corrosion resistance and formability, such as packaging, cooking utensils, and general sheet metal work. 3. 5052: This alloy grade offers a good combination of strength, formability, and corrosion resistance. It is often used in marine environments, as well as in transportation equipment, such as fuel tanks and vehicle bodies. 4. 6061: This is a heat-treatable alloy grade, known for its excellent strength and weldability. It is commonly used in structural applications, such as bridges, aircraft parts, and bicycle frames. 5. 7075: This is another heat-treatable alloy grade, known for its high strength-to-weight ratio. It is often used in aerospace applications, as well as in the manufacturing of high-stress components, such as firearm parts and rock climbing equipment. These are just a few examples of the different alloy grades used in aluminum coils. The selection of the appropriate grade depends on the specific requirements of the application, such as desired strength, corrosion resistance, formability, and thermal conductivity.

I am confused by that. One guy told me that he puts aluminium foil on his modem to receive the Internet better. Another guy told me that aluminium stops all kind of rays. What is correct?

BOTH ARE CORRECT.... COVER THE WHOLE WIRELESS MODEM WITH ALUMINUM FOIL AND GROUND IT SHALL BLOCK ALL THE WIRELESS SIGNAL. CONNECT A SMALL PIECE FOIL TO THE WIRELESS MODEM ANTENNA MIGHT INCREASE THE RANGE A BIT SOME TIME BUT USUALLY NOT WORKING WELL.

What advantages does 0.1*100cm aluminum coil have? Is it suitable for the roof tiling? How is the anti-oxidation and anti-corrosion performance?

It is seldom used as roof tiling because its performance is not as good as color steel panel and its cost is not cheaper than others.

Its got probably 330 horses right now with aluminum heads what do you think it be approx.

everything being equal, aluminum heads will only make your engine lighter, not increase any horsepower. It's possible to buy aluminum heads that Will increase your horsepower, however the aluminum itself does nothing more than lower your weight. A lighter car moves easier.

If you were to make something from each of these.which is more expensive? aluminum or carbon fiber ?which is stronger?What would the advantages or disadvantages of each be?

Oxidation: carbon fibre oxidise and looses strength as it oxidise. The oxidation level is quite low at room temperature but increases with temperature and also chemical contaminant Durability. as seen above CF will not have durability in time as you have with Aluminium. So be mindful as your product will not be as good in 10 years with CF as it is in Aluminium. Also failure mode with CF is much more difficult to predict, analyse and failure are not a controlled as Aluminium. CF will shatter when crack initiate from a minimal defect or chip.

if the resistivity of aluminium is 2.7×10-8 Ωm

Let ρ be the resistivity of the aluminum cable, A the cross sectional area of the cable and l the cable's length. The resistance R of the aluminum cable is now given by: R = ρ·l / A = 2.7·10^-8·(10·10^3) / (π·r?) = 2.7·10^-8·(10·10^3) / (π·(1·10^-3)?) = 85.9 Ω I guess the tricky part is remembering: R = ρ·l / A but when you realize how intuitive this equation is you don't have to memorize it. The resistance R is proportional to the resistivity ρ, so we must have the following in our equation: R = ρ·k , where k is some value governed by the dimensions of the cable! It is logical that the resistance is also proportional to the wires length l. This is logical when you realize that the longer the wire the more obstacles the electrons will have to pass by! Now we have that: R = ρ·l·c , where c is another value governed now by the cross sectional area (only dimensional property left). If we think of the wire as a highway with cars instead of electrons we realize that there is less resistance (higher speed) when the highway has many lanes and is very broad. From this we realize that the greater the cross sectional area the smaller the resistance. R must therefore be inversely proportional to A. We now have: R = ρ·l / A I hope there are no mistakes here :P
