Is non-ferrous metal non-magnetic?

Answer 1

Are you referring to aluminum?

Pure aluminum is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is easily formed, machined, and cast. Pure aluminum is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements have very useful properties. Aluminum is an abundant element in the earth's crust, but it is not found free in nature. The Bayer process is used to refine aluminum from bauxite, an aluminum ore. Because of aluminum's mechanical and physical properties, it is an extremely convenient and widely used metal.

Some Common Uses -

gearboxes, motor parts
Leisure Goods:

tennis racquets, softball bats
indoor and outdoor furniture

Properties -

very lightweight (about 1/3 the mass of an equivalent volume of steel or copper) but with alloying can become very strong.
excellent thermal conductor
excellent electrical conductor (on a weight-for-mass basis, aluminium will conduct more than twice as much electricity as copper)
highly reflective to radiant energy in the electromagnetic spectrum
highly corrosion resistant in air and water (including sea water)
highly workable and can be formed into almost any structural shape
non-magnetic
non-toxic

Answer 2

Ferrous metals are often magnetic, but this property is not in and of itself sufficient to classify a metal as ferrous or non-ferrous. Austenitic stainless steel, a ferrous metal, is non-magnetic, while cobalt is magnetic but non-ferrous. However since ferrous metals are the most common magnetic materials, magnets are commonly used to separate them from non-ferrous metals and other materials.

Common ferrous metals include the various irons and steels. Common non-ferrous metals include aluminium, tin, copper, zinc, and brass, an alloy of copper and zinc. Some precious metals such as silver, gold, and platinum are also non-ferrous.

Answer 3

Yes. Most non-ferrous metals are non-magnetic. It is only a few non-ferrous metals that are magnetic, such as aluminum, nickel, and some of the lanthanide rare earth metals.

Answer 4

Not necessarily. Ferrous (containing iron) metals can be magnetic though not all are. And, there are non-ferrous materials that are magnetic.

Answer 5

yes non ferrous metal are non magnetic

Answer 6

Not always.

Nickel and cobalt can also be magnetized. The strongest magnets in the world are exotic alloys of iron and "rare earth" metals like niobium. Even a gas can be magnetic. Liquid oxygen is one such example.

Answer 7

I don't know what ferrous means, but it's certainly not an alloy. An alloy is a mixture of two or more elements and manganese is its own element.

Answer 8

Correct

Answer 9

It can be O=)

Although the correct term would be diamagnetic. For instance zinc and nickel are ferromagnetic materials.

Answer 10

Yes non-ferous metals can indeed have eddy currents.
