Question

which of the following is non ferrous metal chromite,iron, manganese,not​

Answer 1

Answer:

Manganese is non ferrous.

Explanation:

Manganese is not precisely a "ferrous metal", but it is one of the iron group of elements which originates in the hearts of giant stars before a supernova explosion. A ferrous metal must contain iron and while it is commonly found in ores that contain both the metal manganese itself is actually an element in it 's own right, consequently in its pure metal form, manganese is -not- a combination or an alloy with any other metal. That said; it -is- most often used to form industrially important alloys. It is commonly alloyed with steel in order to improve the strength, toughness, stiffness, wear resistance, hardness, and hardenability of steels for tools and a variety of specific uses.Manganese metal can become "ferromagnetic" only after special treatments with certain process and compounds and in special alloys with aluminum and antimony, most commonly with small amounts of copper.
