Steel is iron and a little carbon.. Iron is the most common impurity found in aluminum. It has a high solubility in molten aluminum and is therefore easily dissolved at all molten stages of production. The solubility of iron in the solid state is very low (~0.04%) and therefore, most of the iron present in aluminum over this amount appears as an intermetallic second phase in combination with aluminum and often other elements.. Alloys are often described by the atomic percentage or weight percentage of the constituent elements be sure to state which!

You should try to study these formulas because they are not to difficult. Aluminum is a metal. So... you should first know that it is an ionic bond. Ionic bonds do not have prefixes, so you don't have to worry about adding them. Phosphate is a polyatomic ion. That means it has it's own "special formula." (Which you should study!) So. . . It should look like this ----------> Al PO4 Btw the 4 is below the O, not beside it.

Al(C 2 H 3 O 2 ) 3 - first, aluminium is in the beginning of the equation and acetate needs to be after. Aluminium has a charge of +3 making it Al +3 -acetate has a charge of -1 and its formula is C 2 H 3 O 2 - Using the crossover method, we see that it would take three acetate ions (-1 charge) to balance out the 1 Aluminium Ion (+3 charge). So the final equation should be Al(C 2 H 3 O 2 ) 3

The chemical symbol of aluminum, a pure element, is Al . Aluminum metal is a pure element, but most aluminum is commonly used as an alloy, a mixture of aluminum and other metals, often with copper, zinc, manganese, silicon, or magnesium. Do note that aluminum is always coated with a protective layer of aluminum oxide (Al 2 O 3 ), resulting in it not reacting with steam even though it is very reactive. This takes place naturally and the only way to stop it is to deprive it from oxygen which is not necessary since the protective layer is what makes it commonly used (or it might react with the gravy or the steam from freshly warmed food)

When it comes to the age-old question of deciding between using 6061 aluminum alloy or 7075 aluminum alloy for a project or task, understanding their differences and application ranges can go a long way and save you the trouble when looking to balance performance with cost. For most general purposes, both alloys may be able to get the job done but the differences in composition, mechanical properties and cost between both alloys can help you determine which of the two is the best choice for your structural needs. In this post, let’s discuss the general similarities and differences between 6061 and 7075 aluminum alloys.
![[Image: 7075-aluminum-plate.jpg]](http://www.aluminum-hot-rolled-plate.com/images/7075-aluminum-plate.jpg)
Composition Differences
When it comes to compositional differences between 6061 and 7075 aluminum, the differences aren’t visible at first glance. Sure, both contain the same alloy agents such as magnesium, silicon, copper, iron, zinc, titanium, manganese and chromium, but the biggest distinction isn’t what’s in your aluminum plate or square rod but rather, how much is in your material.
For instance, 6061 aluminum alloy contains less zinc than its 7075 counterpart, meaning that while 6061 alloys provide superior welding abilities and workability over other alloys, it doesn’t boast the same high strength and stress resistance as 7075 offers.

Applications for 6061 and 7075 Aluminum Alloy
As is the case with many similar materials, 6061 and 7075 aluminum can be used in many of the same tasks and can often be swapped out when costs and risks are deemed suitable to go with a less expensive option such as 6061. That being said, here are general guidelines for uses for each alloy – when making a decision on your material needs, consider these points as a general overview for applications:
6061 Aluminum Alloy Applications
6061 aluminum is highly versatile and can be used for almost any structural component. Commercial and personal use vehicles utilize 6061 for truck frames and running boards, infrastructural uses include mass transit and subway platforms, steps, flooring, walkways and cover plates, and consumer products such as bicycle frames and components, SCUBA tanks, fishing reels and small utility boats all benefit from the increased weldable nature and its ability to undergo hot forging.
![[Image: 6061-aluminum-plate.jpg]](http://www.aluminum-hot-rolled-plate.com/images/6061-aluminum-plate.jpg)
7075 Aluminum Alloy Applications
Because of its high strength-to-weight ratio and improved strength over 6061 alloys, 7075 is largely used in aerospace, marine and transportation industries where strength and light weight properties are critical. High-end bicycle components, molding materials for the plastics and tool industries, glider and hobby-grade airframes and even numerous military applications including assault rifle receivers and precision rifles all benefit from the high polish and improved thermal properties that 7000-series alloys provide.
Mechanical Properties of Aluminum
Generally speaking, aluminum is the second most widely used metal in the world and its physical properties (and its abundance on Earth) explain why. With such traits as low density/low weight, high strength, easier machining and malleability, superb resistance to corrosion and ideal electrical and thermal conductivity, it’s easy to see why aluminum is in demand for metalworkers and numerous industrial applications. While there are numerous alloys and even more temper options available, let’s compare 6061 and 7075 aluminum alloys of the T651 temper variety for a quick side by side:
General Mechanical Properties of 6061 Aluminum (T651 Bare)
Tensile Strength – 45,000 psi
Yield Point – 40,000 psi
Brinell Hardness – 95
Elongation at Break – 12%
Shear Strength – 31,000 psi
Thermal Conductivity – 170 W/m-K
Strength to Weight Ratio: 115 kN-m/kg
General Mechanical Properties of 7075 Aluminum (T651)
Tensile Strength – 83,000 psi
Yield Point – 74,000 psi
Brinell Hardness – 150
Elongation at Break – 10%
Shear Strength – 48,000 psi
Thermal Conductivity – 130 W/m-K
Strength to Weight Ratio: 196 kN-m/kg
Summary – 6061 vs 7075 Aluminum Alloy
In general, when looking to compare 6061 versus 7075 aluminum alloys, 6061 is considered by many to be highly versatile for a wide variety of general purpose mechanical applications. 7075 is one of the strongest aluminum alloys available and while its increased cost and tougher workability may come across as obstacles, 7075 alloys are worth their price tag when it comes to applications in which its increased strength and toughness are crucial.

| What is marine grade aluminum? |

Marine grade means a specific alloy that resists corrosion, and does not deform easily. Alloys in the 5000 series as well as some 6000 are considered marine grade.
5000 and 6000 series aluminums are considered marine grade. Also called T5 and T6. T6 is harder but has shorter life. Yes it does wear out like an old 727. The old DC-3's never wear out because they were made with T3, but they do corrode much faster and are not as strong. T5 is my suggestion for almost anything unless you can use a thicker T3. With any of these remember that disssimilar metals will destroy each other (the harder metals eat the softer metals). So if the rest of the boat is T5, use T5 exclusively. Ask any Aviation Metalsmith and they will babble all day about it,
2052, 5083, 5086 aluminum, belongs to 5000 series alloy and is one of the key products of 5000 series aluminum plate. The main alloying elements of 5086 aluminum alloy are magnesium and silicon. The products have high corrosion resistance, good weld-ability and medium strength. 5086 aluminum can be used in the manufacture of sheet metal, metallurgy, and electrical enclosures for transportation vehicles and ships. Compared with other aluminum products, the anti-corrosion property of 5086 aluminum is an important reason for its wide application.
Therefore, 5086 aluminum sheet plate has also become “rust-proof aluminum plate”. Aluminum-magnesium alloys and aluminum-manganese alloys are collectively referred to as rust-proof aluminum because the alloy components in between have their anti-corrosion properties.
![[Image: Development-of-marine-grade-aluminum-plate.jpg]](http://marine-grade-aluminum-plate.com/images/demo/Development-of-marine-grade-aluminum-plate.jpg)
5086 aluminum plate sheet is one of the hot products that has gradually emerged with the marine economy and plays an important role in the international marine market. Haomei Aluminum 5083 and 5086 aluminum sheet were certified by DNV GL and obtained relevant certificates issued by the Norwegian classification society. As we all know, DNV certification is a universal license for the international aluminum market. Typical uses of 5086 aluminum sheet plate is where high corrosion resistance, good weld-ability and moderate strength are required, such as weldable parts for ships, automobiles, aircraft panels. And pressure vessels, refrigeration equipment, television towers that require strict fire protection, mounting equipment, transportation equipment, missile parts, armor, etc.

| Do you reuse pieces of aluminum foil? |

Aluminum foil is a pretty cool kitchen tool. It can be molded to any shape and can completely block moisture and air if you fold the edges properly. And you can use it more than once. That’s right — more than once![img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/01/1-1F303111T4196-300x231.jpg[/img]
![[Image: 1-1F303111T4196-300x231.jpg]](http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/01/1-1F303111T4196-300x231.jpg)
We’re not just talking about the fact that you can usually recycle it with the rest of your empty cans and jars. We’re talking about the fact that you can recycle the same piece over and over again in your own kitchen.
Cleaning Aluminum Foil
Yep, you can wash and reuse foil. And you don’t even have to hand-wash it: You can actually put it in the dishwasher. The dishwasher! Just place it on the top rack, soiled-side down, and weigh it down with a utensil or something. The flexible metal will clean right up. Although of course, for light soiling it might be faster to just give it a quick rinse under the faucet.
Reusing Aluminum Foil
You don’t even have to clean the foil. Assistant Food Editor Sheela Prakash will often fold a slightly dirty piece of foil in half and use the clean sides in the toaster oven. What if the foil has been crumpled? You can still use it! Just flatten it out the best you can and use it to line a baking sheet or, say, wrap up a piece of pizza. Basically, as long as you don’t rip your sheet of foil and have clean sides to work with, you can reuse it forever.
That being said, if you rip your clean foil, it still has lots of other applications. You can crumple it into a ball to use as a pot scrubber, or cut through the layers to sharpen scissors. You can also scrunch it up to fill space in the bottom of a large planter or to keep your winter boots upright. At the very least, you can use it as an art supply.
