stainless is steel. aluminum is aluminum
The extruded bar would be produced by pushing molten aluminum through a die. Where as the other option for making the bar would be to cast it in a mould. The extruded bar would probably have smoother sides and would be available in longer lengths.
Grab a small magnet. It will stick to stainless steel - it won't stick to aluminum.
i guess your buying a BMW. brushed aluminum is basically an aluminum that is brushed to make it smooth. abraded is like a snake skin but not a snake!!
Use a magnet. Magnets stick to steel but don't stick to aluminum. Stainless is very weakly magnetic at best. Best to identify aluminum from stainless by weight (aluminum is much lighter) or by hardness (aluminum is much softer; scratches more easily). ***************** Though magnet test can show the difference between magnetic steel and aluminum, it cannot show the difference between non-magnetic steel and aluminum. In this case you can tell the difference by 1. weight , since aluminum has density 2700 kg/m3 and steel (magnetic or not) 7500 2. hardness, using a knife or something similar, since aluminum is softer than steel
Extruded aluminum is aluminum that is melted down and extruded, pushed through a certain 2d shaped hole. This can result in square tube, rectangular tube, an L shaped extrude, and an infinite array of other shapes. Powder coated aluminum is aluminum that could be extruded aluminum, that is cleaned, coated with a colored plastic powder, and then baked so that the plastic powder melts and forms a smooth, nice and even coat of colored plastic over the part. This is basically painting the part. Anodized aluminum is aluminum, again this could be extruded aluminum, but it couldn't be powder coated aluminum, that is put in a chemical solution, possibly sulfuric acid, and then a current is run through the aluminum. This causes a reaction to occur where a layer of aluminum oxide gathers on the surface of the part. The processes is then stop and the part can be colored if desired. Anodozing aluminum gives the part better corrosive resistance and makes the surface tougher and harder than it would have been if it had not been anodized. It does add thickness to the part which can be a downside, but it also is lighter than a powder coat if a paint job is desired.
Why yes there is. An extruded clay is something pushed out by a machine and modeling clay is handled by man.
There is a slight difference between aluminum foil and an aluminum rod or powder. This difference is simply the shape it takes.
stainless and silver is defferentbecouse silver is a colour and stainless are stains
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
There's no difference, cause duplex is a type of Stainless Steel, as so ferritic,austenitic,martensitic.
The difference between 18 gauge and 22 gauge stainless steel is the thickness. The 18 gauge is 0.050" thick, and the 22 gauge is 0.031" thick. A link is provided below to an article with a list of the conversions. You'll note that the cited thickness for the gauges of stainless do not apply to galvanized steel, aluminum, zinc, brass or other metals.
They are both pretty hard to chew, and have little nutritional value. But seriously, it depends on what the application is. Aluminum is lighter. Stainless has other advantages. Each material corrodes in ways the other does not.
