Non-ferrous metals in production and construction.

Non-ferrous metals in production and construction.

To color

Metals are all metals, for

Except for ferrous metals and,

Accordingly, their alloys. Colored

Metals can be divided into several

Species. Heavy metals include zinc,

Copper, lead and nickel. To light metals

Include magnesium, titanium and aluminum.

Platinum metals are commonly called

Noble. The indicated types of colored

Metals, in turn, are divided

On a number of subgroups, which, incidentally, have

A very conditional division. Thus, some

Specialists subdivide color

Metals on rare-earth, refractory,

Radioactive and dispersed metals.

Non-ferrous metals have another name

- Non-ferrous metal rolling. To color

Metals can include some

Elements in the periodic table, which

Valence and their inertness is slightly increased

When interacting with other substances,

If compared with conventional metals.

It is after processing of non-ferrous metals

Can rightfully be called colored

Rolled metal products. Such processing

Is produced by several methods. When

It should be noted that

The more modern and mobile method

Production of non-ferrous metals,

The final result is more qualitative

Product made. By the general rule

To non-ferrous metallurgy include mining,

Enrichment of non-ferrous metal ores, and

Their production. Proceeding from what has been said,

We can say that non-ferrous metallurgy

Is a branch of metallurgy and includes

Extraction, enrichment of ores of non-ferrous metals.

The location of the enterprises is colored

Metallurgy is directly dependent on factors

Economic order, as well as from

Natural conditions. The role of the notable

Character here can play and

Fuel-energy factor. On

Territory of our country was formed

Several databases that directly relate to

And now to non-ferrous metallurgy.

The dissimilarity of their specialization can be

Explained in the differences in the geography of the lungs

Metals, as well as heavy metals.

It should be noted that production

Heavy metals has a need for

Small amount of energy. Due

With this, the production of these metals

Is confined to the areas of extraction of raw materials. Other

The situation is formed by the extraction of light

Metals, where a large

Amount of energy. This circumstance

Dictates the concentration of enterprises,

Which smelted light metals.

Non-ferrous metals according to their purpose

Are an element that

Significant and important for metallurgical

Industry. Extraction of natural

Metal is limited by the sources of nature

And, accordingly, can not fail to appear

Process is rather difficult and protracted.

The use of scrap metals can competently,

And most importantly economize resources

Our country, which is impossible

To make up. In the classical pure form

Non-ferrous metals are very rarely used

In construction. Quite often find

Alloys of non-ferrous metals,

Which by the criterion of their density

Subdivided into light and heavy.

Use of non-ferrous metals in

Production occurs, mainly in the

Form of alloys, and less often, in the form of pure

Metal. In general, the use of metals

Necessary to protect against corrosion,

Engineering use metals in

Form of a powdery substance. Besides

Mentioned branch, wide application

Nonferrous metals have in shipbuilding,

Aviation, and missile technology. Also it is impossible

Bypassing the attention and electronics, atomic

Equipment, instrumentation, radio engineering.

It's no secret that modern industry

Has a need for light-alloy alloys and

High strength. They have

Following characteristics: high

Strength and high-temperature

Properties. To the basic metals of the lungs

Alloys can be handled with all responsibility

Include aluminum, magnesium, titanium, beryllium.

Alloys based on aluminum and magnesium are not

Can be applied under the condition of high

Temperature and in environments of aggressive

Character. Heavy alloys are manufactured

From copper, zinc, lead, and also from tin.

Among alloys of heavy type in construction

Now finds its application

Bronze, brass. It is from them that they make

Details for architecture and fittings

Sanitary and technical purpose.

In addition, non-ferrous metal is used

In the manufacture of equipment that has

Different purpose. In the Russian

Regions there is a production of this

Raw materials in large quantities. One of

Most popular and common

Non-ferrous metals are zinc and

aluminum. Zinc is a non-ferrous metal,

Which is to be forged and rolled at

Condition of its heating about one hundred and fifty

Degrees. At a temperature of less than

Degrees, this metal is brittle

Construction. The properties of zinc can be

Carry the fact that the metal in question

Not afraid of corrosion. However, zinc and

Has the properties of resistance to action

Acids of alkaline type. Zinc fusion

Occurs at a temperature of four hundred

Nineteen degrees Celsius.

Aluminum is different from zinc. This difference

Is that the properties of the given

Metal of a mechanical nature are low

And are preserved even at sufficiently low

Temperature regimes. It is impossible not to note

Such an property of aluminum as thermal conductivity

And plasticity. It is aluminum

Belongs to a significant part and area

Application in the food industry, then in

Construction, rocket construction and

Aircraft construction. Another obvious

The advantage of this metal is that

It has a low density, so

Less, has great strength. Copper

As a non-ferrous metal has a larger

Compared with previous metals

Spread in nature. Copper has

Such characteristics as thermal conductivity,

Electrical conductivity, ability to

Melting. It is due to the described

Properties this metal has acquired extensive

Distribution and scope

- Mechanical engineering. In addition, copper found

Its place in the manufacture of vessels,

Different capacities, pipelines

Different purposes. Additionally,

It should be said that in the aircraft industry and

Chemical industry are applicable

Such metals as hafnium, titanium, molybdenum,

zirconium. Proceeding from this, it becomes,

It is obvious that the field of application of color

Metals is very diverse. Specific

Colored metal has a number of properties,

Thanks to which he is referred to

Defined group of non-ferrous metal.

Most non-ferrous metals have a common

Properties can be attributed heat capacity

And thermal conductivity with high indexes

And rapid cooling after welding

Works. It would seem that this is unconditional

a plus. But not everything is so simple in nature itself

Of the metals under consideration. This is an advantage

Can turn into a disadvantage. For example,

When working with a metal such as magnesium

And the copper parts must be heated

Solely before welding,

In the process of using sources

Heat of a powerful type. Further, when heated

Non-ferrous metals

Of a mechanical nature, from this

It follows that it is tiresome not to strike at

Manufactured products on

This stage of production. If colored

Metals compare with ferrous metals,

Then it should be noted a very big drawback

Non-ferrous metals. This is what they are

pollute the environment. The thing is

That at large volumes of heating

Non-ferrous metals, of which

Gases that interact with the surrounding

Medium. The most dangerous in this respect

Such non-ferrous metals as titanium, tantalum,

molybdenum. By the way, tantalum is a color

Metal, which is often called

Active metal precisely because of this

Not a very good property. But we will return

To the undoubted advantages of color

Metals. All non-ferrous metals have

Long enough time

Operation provided that they are

Protection from oxygen will be provided.

It is under the influence of oxygen that they

Are being destroyed. In order to protect the color

Metal from corrosion processes, on

Paint materials are applied to it

Destination. They have properties

Protective nature. Primers and paints

Also needed and useful for color

Metals. Coating of the metal with paint

Can avoid oxidation, and

Allows to carry out a primer. When

It is necessary to apply a primer

Understand that different metals must

Be primed with a different composition.

For example, to an aluminum base

A zinc primer is required. For example,

Bronze and brass are processed in

Specialized organizations

Special formulations, which in the case of

You can delete

Substance, as a solvent. Based

Stated, we can say that the color

Metal is an essential element,

Used in various spheres

Life-support of society, which

Has a certain specificity,

Which must be understood.
