Magnetism for kids A simple introduction

Sep 26, 2018· Iron has a Curie temperature of 770°C (1300°F), while for nickel the Curie temperature is ~355°C (~670°F). If you heat an iron magnet to 800°C (~1500°F), it stops being a magnet. You can also destroy or weaken ferromagnetism if you hit a magnet repeatedly....

Nickel Simple English Wikipedia, the free encyclopedia

Nickel is not normally found as a metal in the ground. Sometimes meteorites have nickel and iron metal in them. Normally nickel is in minerals. The most common nickel mineral is pentlandite. There are sulfidic and lateritic nickel ores. Philippines mines the most nickel. Other major mining countries are Russia, Canada and Australia....

List of alloys Wikipedia

Low alloy steel is alloyed with other elements, usually molybdenum, manganese, chromium, or nickel, in amounts of up to 10% by weight to improve the hardenability of thick sections. High strength low alloy steel has small additions (usually < 2% by weight) of other elements, typically % manganese, to provide additional strength for a modest price increase....

Iron Nickel Zinc Oxide | AMERICAN ELEMENTS

Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite. Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger....

Oct 29, 2003· Stainless steels. The most common stainless steel is the 304 grade with 8% nickel and 18% chromium and the balance iron. This is used for such common items as spoons and forks, saucepans and kitchen sinks. Where extra corrosion resistance is required, such as for roofing in marine applications, type 316 is used....

Magnetite: Mineral information, data and localities.

Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007)....

Magnetite Facts Figures | The Magnetite Network

The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers....

Soft Iron Based Magnetic Alloys | SSI Technologies, Inc.

Soft magnetic alloys are ferromagnetic materials that are easily magnetized and demagnetized. To provide optimal magnetic performance, these alloys possess very low levels of carbon, nitrogen, and oxygen. They rely on various additions of phosphorus, nickel, and silicon to optimize magnetic induction, permeability, and coercive force....

Chemistry for Kids: Elements Iron Ducksters

Iron is the most naturally magnetic of the elements. Other naturally magnetic elements include cobalt and nickel. Iron becomes significantly harder when alloyed with other elements such as carbon. Iron can be found in four allotropic forms. The most stable form of iron at normal temperatures is alpha iron which is commonly known as ferrite....
