Non-ferrous metal rolling.
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.
Non-ferrous metals include:
Which is used as a different
Raw materials, wires, radio engineering, cable
Products and other industries.
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
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.
Brass add tin, manganese,
Aluminum to give the alloy the right
Physical properties. Brass from copper and
Zinc is called simple.
Brass contains up to 10% of different alloying
Elements that are reflected in
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
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
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
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.
Alloys are divided into several types:
Casting and processed by high
Pressure. The foundries are labeled,
Mean the number of the alloy. Deformable
Alloys - also in letters and numbers.
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.
With its alloys have increased
Corrosion resistance in air,
Strength, electrical resistance,
Heat resistance 0 plasticity.
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.
Is an alloy of chromium with nickel, since
Nichrome has a significant specific
Resistance and heat resistance, then its
Used in electric heating
