in metal tec we have been learning about different types of metal and there purpose here is a slide that me and my friends have made
in tec we are making a f shape and a drill gage we have started making the f shape to test are skills with cutting metal
Metal Classification
by John, Anaru & Daunte
The definition of a ferrous metals:
Ferrous is the definition of a metal containing iron. All metals that contain iron are magnetic and a ferrous metal. The magnetism relates to the iron compound. When seeing the symbol Fe2+ indicates the presence of iron. Ferrous metal are prone to rust and corrosion.
Different types of ferrous metals
Steel is a ferrous metal because of its properties of iron and carbon. Carbon is the element that provides its strength. Other elements of steel are chromium, nickel, and molybdenum. Steel is widely used in the production of household appliances, structural engineering, roads and rail. Steel is cheap and easy to make, providing a base for many uses around the world.
Cast iron is great in the production of cookware. It is a non stick pan. Cast iron is great in cookware because of its low melting point. Cast iron provides a good service for bbqs in the way that it retains heat. By retaining heat, provides a faster cooking time. Other example of uses of cast iron consist of. Bridges, engine blocks and heads, casting molds, lamp post, and plumbing.
Non-Ferrous Metals
The definition of non-ferrous metals. Metals that don't rust and don't contain iron.Ferrous meaning metals that have iron.and are generally more expensive and they are non conductive
properties of non-ferrous metals:non conductive/are expensive/good at conducting
Alloys
An alloy is a mixture of metal and another element from the Periodic Table. There are three types of Alloys. Heat treatable, substitutional and interstitial alloys.
Heat treatable Alloys are stronger than standard aluminium. This is achieved by adding alloying elements to pure aluminium, then heating it up. Typical elements include but are not limited to Copper, Magnesium and Silicon.
Interstitial Alloys are typically incredibly strong metals, because small atoms such as carbon can sit inside the gaps created by the larger Iron atoms, allowing them to be tightly combined.
Another type of Alloys is Substitutional Alloys like Bronze and Brass. These are where copper atoms are substituted for tin or zinc atoms. This allows different atomic mechanisms to increase strength and change formation.
