Non-ferrous metal rolling.

Non-ferrous metal rolling.

Colored

Metals are copper, nickel, magnesium, titanium,

Aluminum and others. These metals and their

Alloys have different properties, for

The account of which is widely used

In the household.

TO

Non-ferrous metals include:

Copper,

Which is used as a different

Raw materials, wires, radio engineering, cable

Products and other industries.

Copper

Has a significant thermal

Conductivity in hot and

Cooled state. Saves

Mechanical properties at low

Temperature, when steel becomes

Are fragile. Copper melting point: 1083

Degree.

Technical

Copper is constantly characterized by letters

And figures that indicate the content

Impurities. The larger the figure in copper than

More in it of various impurities. In view of

Small strength of pure copper

Alloys from copper are used.

AT

Brass add tin, manganese,

Aluminum to give the alloy the right

Physical properties. Brass from copper and

Zinc is called simple.

Specials

Brass contains up to 10% of different alloying

Elements that are reflected in

Marking.

Ways

Processing of brass is divided into processing

Pressure and foundry. Foundry pressures

Are marked, indicating the alloying

Elements with a mass fraction in percentage,

And all other content is

copper.

Bronze

Is an alloy of tin with copper, iron,

Nickel, phosphorus and other metals.

The chemical composition of bronze is divided into

Without tin and pewter. Most

Famous bronze with the addition of tin

to 10%. However, tin is scarce enough

And it is replaced by aluminum. It is worth noting,

That the marking of bronze is the same as that of

Brass.

Aluminum

Refers to the heat conductive and

Corrosion-resistant metals. Aluminum

In its pure form, soft and fragile, namely

So he found the use of alloys

Copper with aluminum, magnesium, silicon,

Which have sufficient strength

On the similarity of low-carbon steel.

Foundry and deformable - the two main

Type of aluminum and alloy. Formed

Dense oxide film over the surface

Is caused by the oxidability of aluminum

Protecting metal from oxidative

Processes.

Magnesium

Has low mechanical properties,

Is unstable to corrosion,

That is why it is not used in the form

Structural material, but its

Rather widely used with aluminum,

Zinc in the instrument making industry.

Magnesium

Alloys are divided into several types:

Casting and processed by high

Pressure. The foundries are labeled,

Symbols that

Mean the number of the alloy. Deformable

Alloys - also in letters and numbers.

Titanium

With its alloys a fairly new

Structural material, beyond which

The first place in the technique of the new generation,

Because of the strength of titanium exceeds

Stainless steel. However, he has

Lack. Titanium is able to actively

Interact with gases at

A slight increase in temperature,

Which leads to reduced plasticity

And increase the strength.

Nickel

With its alloys have increased

Corrosion resistance in air,

Strength, electrical resistance,

Heat resistance 0 plasticity.

Monel

Is an alloy of copper with nickel and manganese.

Such an alloy for its corrosive

Durability is close to nickel, that

Exceeds its properties under its

Small cost. He found application

In the chemical industry, in mechanical engineering.

Nichrome

Is an alloy of chromium with nickel, since

Nichrome has a significant specific

Resistance and heat resistance, then its

Used in electric heating

Devices.
