Metals

metals. Today, we're going to be looking at the different

types of metals using in manufacturing.

I'm part of design, so let's go into our introduction.

So I aims and objectives today at understand how metals

are categorized.

So how we can identify if a metal comes from

Mesa category, we're going to try analyze unidentified different metals,

but in particular focusing on the properties off these metals.

And then hopefully what you should be able to do

is identify products made from a certain type of males.

So first, let's take a quick look at how metals

are categorized, so the categories of metals you can split

them into free, simple categories.

These are ferrous metals, nonferrous metals and Eloise.

A Ferris metal is simply a metal that contains the

elements iron in non Ferris, these metals that don't contain

iron or a higher mind.

Tobias on an ally is a combination off two or

more metals, so we're gonna know looking a bit more

detail at each of them categories, we're gonna identify the

properties of different metals and give you some products, so

we'll look at ferrous metals first.

So ferrous metals, as we discussed they contain iron.

So this means that magnetic okay, it's the iron within

a metal.

That means it becomes magnetic.

Now. There are lots of different properties off ferrous metals,

and not every metal has a specific property that's related

to another type.

So we're just speaking generally here.

But generally, ferrous metals are very high strength, so that

you can see here in this picture of the steel

girdle. It's used in construction a lot.

Something that's high strength is needed because of the iron

and carbon elements in there.

It corrodes easily.

This means that it rusts, so there's a good indicator

if you ever want to spot whether a metal is

a Ferris of non fares.

If it's roasting, it's highly likely that it's a Ferris.

So the very widely used as we discussed, they're using

constructions. You can see this is some steel used for

a building.

It's used in railway lines, bridges, anything that's hi, friend,

but it's also using different elements as well.

So you can see here is used some stainless steel

in kitchen utensils on.

We've got an iron skillet here.

So what we're gonna do, we're gonna have a look

at some specific ferrous metals.

These are carbon steel, stainless steel, my own steel and

cast iron.

There are countless small we're just gonna focus in on

these. So let's look at carbon steel, so campuses are

very commonly used.

The product primer, merrily made up of iron on the

rest of their composition, is carbon.

Hence the main carbon steel.

And there are only trace amounts of all the elements,

So common applications of Captain Steele include structures so good

as we looked at furniture on automotive components you're looking

at CASS.

The bodies of the Cavs is most likely cabin steel.

Let's look at stainless steel, so stay in the steel

is a number of widely used ferrous metal.

They have high months of chromium.

It's the chrome ian in a stainless steel that makes

it becomes stainless.

There are countless different types of stainless steel, but we

just need to know that stainless steel generally resist corrosion

on because it resists corrosion, which means rusting.

It's widely used in things like pharmaceutical and medical equipment,

so if you go into a doctor's, there'll be lots

of stainless steel equipment.

It's also used in food preparation, and so we manufacturing

and fruit preparation, but also in your home.

Your nice or faults would generally stainless steel.

Let's look at mild steel, so mild Steel is another

type of steel that is used very commonly.

It contains a small amount of carbon on.

This makes it more acceptable to use for a wider

range of applications.

So unlike over grades of carbon steel because of the

high carbon and iron ratio, it tends to be brittle.

Mild steel is hard yet malleable, so malleable means you

can bend it and shape it without its snapping.

So this is the perfect choice for things like construction,

um, cars, motorcycle frames, pipes.

It's even used in different types of cookware.

Hello, mild steel can be known to roast.

It's got poor corrosion resistance.

Usually it's got site, some kind of corrosion resistant coating

or painting on it.

Just prolong its life.

And then finally, let's look at Castalia.

So Castilian is a type of metal, has lots of

high carb.

It gives it a higher my coughs cramp.

OK, so it's very high in its cramped but cast,

Hein can be brittle, which means under pressure it can

snap, and so the lack of over are lying elements

outside of iron and cab and make it relatively affordable.

Because it's only two elements in this metal.

It's relatively cheap composed compared to a normal type of

a lie.

Common applications includes cookware, um, components such as gears, rods

and pins on mining equipment.

Castilian, Azat as well on different types of wines, are

usually used in gates.

And so if you see a gated house, it's probably

a cast iron or brought.

I am has So they're ferrous metals.

Let's look at nonferrous.

So non ferrous metals is very hard, nearly impossible to

come up with a specific general list off properties cause

there's such a large right of different metals that fall

into this category, it's impossible to try and give general

properties. Some non ferrous metals are hard but brittle, which

means they're hard.

What can snap?

And so my soft and doctor Dr means they could

be stretched and bent into shape, so they're very commonly

used. But as we can see here, we're focusing on

Allah minion, copper and nickel.

So with aluminium, so it's a silver colored, low density

metal, so lightweight metal it's used Mary very widely so

the on our lives.

Hype is Doc tile, which means it could be stretched

into different shapes.

Stretch without breaking.

He's got moderate strength compared to its weight so high

shrimp to weight ratio on its very good with corrosion

resistance. It doesn't rust easily, so the fact that it's

low density, um, it's got high strength means it's used

in aerospace soul of the airplane, Um, structures.

Cabins would be made with aluminium on Dover transportation fields

and the fact that it's corrosion resistance means it's used

in food and chemical handling.

So things like cookware, you can have all a 1,000,000

cans. It's also used in building.

So because it's high strength to weight can be used

in architectural to my ever another 1,000,000 window frame.

Let's look a couple so Cup has good to excellent

corrosion resistance so it doesn't corrode easily has very high

firm all conductivity on dhe electrical conductivity.

This means it conducts heat and electricity extremely well.

Because of this, it's widely used in circuit boards, electrical

components, but it's also used and heating, so is commonly

used in the house.

The wires in your home which turned on the lights.

There'll be copper, the pipes that lead to your radiators

and make sure the hot water moves around.

The heist house will likely be copper off.

The applications include architectural uses used in coinage as we've

already identified plumbing radiators.

It's used in some musical instrument components, and, as we

said, it's most common.

Uses electrical connectors, so in your phone.

Smaller slightly.

That couple refused to certain elements, but also in the

hole. So couple can also become an ally with different

types of metals.

Eso common problem allowing elements include 10.

So if you combine copper and tin, that will give

you bronze.

And if you combine copper and zinc, that will give

you brass.

So these are very good are lying metals.

And then let's look at nickel.

So nickel is another popular non Ferris ally, so it's

not really known to be used on its own is

usually combined with a different type smell.

So is known for his toughness.

He's got good ability.

Teoh perform in high and low temperatures, and it's got

good corrosion resistance.

So, as we've said, Nicholas not often used in its

pure form, just like copper and aluminium, it's often allied

with different elements and that will change its properties.

So common applications of nickel, um, include equipment such as

tanks, um, aerospace equipment.

So hot sections eso things like combustion chambers in the

engine and marine equipment.

So stuff that doesn't corrode but has to withstand high

temperatures. So this is a very common metal type.

Your home will have countless different types of ferrous metals

in there.

There were countless over categories, so you can have do

a little bit research.

Try and find a few more, and they finally quick.

Just a reminder.

One ally is so why we use our lows.

Metal are lies they used because they either enhance or

change a mechanical or chemical property.

So mechanical would be things like strength malleability, the ability

to withstand impacts, hardness, toughness, them kind of things and

chemical properties.

Different types of al eyeing elements can be added to

a metal to increase things like hardness, scrimp, corrosion, resistance,

machine ability, machine ability being how easy is it to

court and work with in shape, and this kind of

sylvus as we've kind of covered already, alloys can be

split between Faris allies on nonferrous allies.

In fact, the over two categories are all some examples.

Often, Ally there is very rarely a metal, which is

a single element, is gonna have a certain percentage.

Be a carbon, be a 10 B, a copper.

They usually mixed with different types of metals to change

the properties.

So there we are.

We've identified the free categories, which are fairest, not Faris

and allies.

We've had a look at some specific metals on their

properties. I'm We've identified a few different products or uses.
