The Difference Between Brass and Zinc - Buckleguy

Zinc meanwhile is a highly corrosive metal (not an alloy, so its elements cannot be affected to reduce corrosion resistance). Though with proper laquering or coating, the zinc can be protected from oxidizing effects. And perhaps the biggest reason why brass is superior to zinc is its durability.

Can Brass Be Magnetized? | Sciencing

Apr 25, 2017 · Magnetism affects ferrous, or iron-like, metals such as iron, nickel, cobalt and steel. Brass is a combination of copper and zinc, so it technically is nonferrous and incapable of being magnetized. In practice, however, some brass items contain at least traces of iron, so you may be able to detect a weak magnetic .

Copper and zinc can be used as a wire. Is this true? - Quora

Copper is used as a wire for electrical conduction - in transmission lines, domestic wiring, electric motors and generators. Aluminium is also used for some of these applications being cheaper and lighter to copper. Silver and gold can also be dra.

does a magnet attract copper ?why? | Yahoo Answers

Jan 17, 2010 · The new Neodymium magnets are strong enough to interact with copper or aluminium. A disk Neodnium magnet will slide down a sheet of copper or aluminium much slower than a comparably sized disk of other material. This results from electric currents being set up in the metal by the passing magnet. The resulting magnetic field holds the magnet.

Doping ferrite nanocrystals with various metals, such as chromium, copper, manganese, and zinc are usually used to improve some of their electric or magnetic properties [20-22]. For example, Zn/Ni ferrites have applications as soft magnetic materials with high frequency (due to high electrical resistivity and low eddy-current loss [8]).

Identify Metals: 17 Steps (with Pictures) - instructables

Ferrous means that the metal has iron content which in most cases makes it magnetic and nonferrous means it doesn't have iron in it. An example of a ferrous metal is mild steel, also known as low carbon steel. An example of a nonferrous metal is copper or aluminum. Its always a good idea to bring a magnet to the scrap yard.
