Main Feature of Al-Zinc coated steel coil

1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will  form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside. 
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover. 
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials. 
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

Q:Engineering Materials - tool steel question?
It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
Q:GUITAR! is this nylon or steel? - fingerstyle?
In that video, he is using a steel-string acoustic guitar. However, when choosing between a nylon string guitar and a steel string guitar, you must consider a few things. Steel-string guitars are more painful in the beginning for the fretting hand, but that means you'll have more strength in your fingers faster. Nylon-string guitars are easier on the fingers and sound much smoother and calmer than steel-string guitars. Also, nylon-string guitars have a wider neck and that neck meets the body at the twelfth fret, while most steel-string guitars have a thinner neck that meets the body at the fourteenth fret. Have fun with your first guitar! :)
Q:How do I remove rust spots from stainless steel?
I recommend using a product called Bar Keepers Friend. It is a household powder cleaner like Ajax but it has a mild abrasive that works on stainless steel and other surfaces. It will remove the rust without harming the stainless steel.
Q:How to get katana in Red Steel?
Sure.
Q:Why are most homes framed of wood rather than steel?
Basically, it's because wood was available first and wood is still the cheaper, more widely available material. Way back when man started building dwellings similar to what we have now, steel was not an option for the masses. The process probably hadn't even been invented or perfected yet, there was not the widespread transportation of goods that we have today either. Early shelters were not even put together with nails, they use wooden pegs because metal was so expensive and not widely available. I can't say that it would be better for the environment; it takes a tremendous amount of electricity to smelt and produce metals. And you have the emissions problems from the factories and the power generation. I'd have to do more research on that one. A managed timber stand actually reduces greenhouse gasses and every scrap of that tree can be used in one form or another. The only energy expenditures are moving the trees to the saw mill, cutting at the saw mill and transportation of the goods after that point. And that would be a lot less than the power required to make the same number of feet of steel products.
Q:Steel Fabrication?
Steel fabrication involves the joining together of different types and sizes of steel members e.g when you are constructing a truss. This will include welding or bolting together those members as specificified on engineering drawings though sometimes you have to design/provide a suitable connection yourself. You have to ensure that all connections are adequate/ will not fail in service. You will also have to produce steel fabrication drawings showing various details and these you will send to the design engineer for his approval before you commence the actual fabrication.
Q:What grade of steel is best for a permanent magnet ?
The type of steel you require is Steel ( Iron + Carbon, mainly.),{many different types of steel } with a high Cobalt and Nickel content. These alloyed together give the best Permanent Magnets, mainly due to their own individual magnetic properties / characteristics being retained in the Alloy. All 3 metals can be magnetised by there own, but Cobalt is known to cause cancer. Nickel, is poisonous and can also cause sever Dermatitis and the destruction of skin tissue.But when alloyed together with Iron they are pretty harmless. Interesting thing is, All of these metals (in this case Elements) can share the same Mass Number ( 60 ). And yet are totally different in their other properties beside Magnetism. Cobalt - Samarium - alloys, create some of the worlds most powerful permanent magnets. And were used in medicine, But are now superseded by Neodymium magnets which are employed instead. Edit; What you could try is, mild steel which is widely available and easily found. . The steels mentioned above are pretty exclusive materials and I personally would not know how to test for their contents, of which they are made from. Soft Iron is good for making electro-magnets if you fancy a go at making one. .
Q:8cr13mov steel thoughts?
8Cr13MoV is a decent blade steel...not a great steel, but about as good as you will generally find without paying much higher prices. It's used by a number of well known knife makers... It's basically equivalent to AUS-8 and will work and hold an edge reasonably well for most basic cutting chores. *************************************** From Wikipedia, the free encyclopedia: 8Cr13MoV, a Chinese stainless steel tempered at the Rc56 to Rc58 range and used in the Tenacious, Persistence, Ambitious, Resilience, Grasshopper, Kiwi3 and Byrd lines of knives. Often compared to AUS-8, but with slightly more Carbon.
Q:Can I put phosphor bronze guitar strings on an acoustic guitar with steel strings?
Yes you can. In fact, I prefer phosphor bronze strings to standard steel on my acoustic guitar. I think they play better, feel better, and sound better. My favorites are the D'Addario phosphor-bronze medium gauge.
Q:difference between steel and fiberglass?
Steel will be heavier but easier to manufacture. There won't be a huge weight advantage because you can use steel mesh which works the same as solid, near enough, as an electromagnetic reflector. Steel can just be pressed, fiberglass has to be laid up of resin and mat and then allowed to cure. Fiberglass will also need to be coated in something conductive whereas you can just spray paint the steel, or even buy it pre-coated.
