What is the use of Nipermag?

Hint: Nipermag is an alloy which is a combination of more than two metals. This alloys is used for making a permanent magnet which can be used in loudspeakers, clocks.

What is Nipermag made up of?

Answer : Nipermag is an alloy of iron, nickel, aluminium and titanium.

What are Nipermag and alnico?

Both alnico and nipermag are alloys. While alnico is an alloy of iron, aluminium, nickel and cobalt, nipermag is an alloy of iron, nickel, aluminium and tin. Both these alloys are used for making permanent magnets, which are used in sensors, microphones, loudspeakers, clocks etc.

What is the composition of alloy alnico and Nipermag?

alnico is an alloy of aluminum iron nickel. and cobalt used to make permanent magnents. Nipermag is an alloy of iron that containing nickel, aluminium and titanium.

Does copper and zinc make brass?

Brass is mainly an alloy that consists of copper with zinc added. Brasses can have varying amounts of zinc or other elements added. These varying mixtures produce a wide range of properties and variation in color.

What does iron and nickel make?

Chemistry and technology In steel metallurgy, nickel is alloyed with iron to produce maraging steel and some low-alloy steels. Other technological uses include Invar and Mu-metal.

What is called the alloy of aluminium nickel cobalt?

Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence acronym al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets.

What is the most powerful magnetic object in the universe?

magnetar
The “magnetar,” or magnetic neutron star known as Soft Gamma Repeater 1806-20, is the most powerful known magnetic object in the universe.

What are soft and hard ferrites?

Hard ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors. Soft ferrites have low coercivity, so they easily change their magnetization and act as conductors of magnetic fields.

Why is copper used for pennies?

Since ancient times copper has been used in coins; the Romans used copper widely in this application. The reasons for using copper are its excellent corrosion resistance, ease of stamping, good electrical conductivity for vending machines and ease of recycling.

What is nickel-iron used for?

In steel metallurgy, nickel is alloyed with iron to produce maraging steel and some low-alloy steels. Other technological uses include Invar and Mu-metal.
