Metal

Today, non-ferrous metals are very important in producing any type of equipment. Metal chemically simple substance with properties such as hardness, thermal conductivity, electrical conductivity, and externally with a distinctive color. There are several classifications of metals, basic metals groups are defined to:

  • Ferrous metals (iron and its alloys);
  • Non-ferrous metals (all other metals and alloys, with the exception of iron);
  • Precious metals (silver, gold, platinum, and other platinum group metals);
  • Light metals (low density);
  • Heavy metals (non-ferrous metals, with a density greater than the iron).

Non-ferrous metals – technical name for all metals and their alloys (with the exception of iron and iron alloys, which are called ferrous metals).Scientifically valid classification under the provision of the non-ferrous metals are classified according to various characteristics specific to one group or another:

  • light metals (aluminum, titanium, magnesium);
  • heavy non-ferrous metals (copper, plumbum, zinc, tin, nickel);
  • precious metals (including platinum);
  • fire resistant metals;
  • dispersed metals;
  • radioactive metals.

Non-ferrous metals demand is high and production is widespread in all regions.

Non-ferrous metals metallurgy – metallurgical branch, which includes saturation of ore and non-ferrous metals and their alloys extraction. Distinguish between light metals and heavy metals metallurgy.


The main non-ferrous metals

Aluminum

Aluminium – it is non-ferrous metal, which is characterized by high electrical conductivity, good plasticity, but with low mechanical properties. Divided into primary and secondary aluminum.

Aluminum application. Aluminum is widely used as a structural material. The main advantages of aluminum: 

  • metal is lightweight;
  • easily swaged;
  • corrosion resistant (aluminum ore immediately gets covered with a tough aluminum foil Al2O3, which prevents the further oxidation process);
  • high thermal conductivity;
  • aluminum compounds are not toxic.

The main aluminum as a structural material defect is – a low resistance to flexure, therefore it usually melts with a small amount of copper and magnesium (alloy called duralumin).

Aluminum electrical conductivity similar to copper, to all of the aluminum is cheaper than the latter. Therefore, it is widely used in the manufacture of electrical wires to screening, and even used at manufacturing microchips. It is true that aluminum as a material has an unpleasant feature – because of its solid oxide film is difficult to solder it.

Aluminum is widely used in various kinds of modes of transportation. Currently, aluminum alloys are widely used in aviation, it is almost the main structural material for aircraft production. Aluminium and its alloys are increasingly used in shipbuilding. From aluminum alloys are manufactured housings, superstructures, communication and various types of marine equipment.

Currently, studies are made of aluminum foam as a very strong and lightweight material.

 

Copper

Copper – a metal, which is most common in non-ferrous metals, the high plasticity, electrical conductivity and high thermal conductivity. Copper melts very well with most metal alloys that are used widely in industry.

Zinc

Zinc – is non-ferrous metal, which at normal temperature is fragile, but heated to 100-150 degrees is well formed and rolled. Zinc is corrosion resistant, but not resistant to acids and alkalis. Melting point – 419 degrees.

Use of Non-Ferrous Metals

In today’s technology industry, non-ferrous metals and their alloys steadily growing, thanks to the rapid development of aircraft, missiles and nuclear technologies, chemical industry development. The design of the production, this time began to use metal and extracted based alloys such as titanium, zirconium, nickel, molybdenum, niobium, and even hafnium and, etc.

Copper and its alloys are widely used in the chemical industry, various destination pipes, tank manufacture, in refrigeration equipment production, etc.

Aluminium and its alloys are used in chemical and food industries. Alloys of aluminum is widely used in aircraft, missiles, ships, construction, etc. Thanks to its relatively high strength at its low density, high resistance to corrosion and aggressive environment and thanks to the high mechanical properties at low temperatures.

Non-ferrous metal properties

Some metals (copper, magnesium, aluminum) has a high thermal conductivity, which causes a rapid cooling during welding, in which case it is necessary to use more powerful heat sources for the metals being welded, and in some cases, the materials, and pre-lining.

There is some metals, such as copper, aluminum, magnesium and their alloys mechanical properties decrease upon heating, resulting in a particular temperature metals becomes not resistant to impact or welding seam exposed to decompose under its own weight, it is typical for aluminum and bronze.

All non-ferrous alloys, heated emit a much larger amount of gas than the ferrous metals, destroys the atmosphere and chemical works in conjunction with other gases (except the noble gases). Especially active in this regard is more resistant and chemically active metals such as titanium, zirconium, niobium, tantalum, and molybdenum. These metals usually divides into fire-resistant, and chemically active groups.

Non-ferrous metal processing properties

Non-ferrous metals are durable and reliable, able to withstand high temperatures. Disadvantage is only one – the ability to decompose exposed to acid medium. One of the most effective methods for protecting ferrous metals from atmospheric corrosion effects of the application of protective coatings. There are three groups of measures to protect metal surfaces: Priming, painting and multi-purpose products “three in one”. Primer – an indispensable tool in the fight against atmospheric oxidation of one or two layers of coating is applied before painting, in addition to security features improves the last painting adhesion to the substrate. When choosing a primer it is important to know that different primer is used for different metals.

For various aluminum profiles are used a special primer which is based urethane paint or zinc. Copper, brass and bronze are not painted – these metals in the market are already included factory machining. If such a “corporate” coating over time is violated, it is a best surface to completely remove with solvent, then the base should be polished, and covered with epoxy or polyurethane polish.

Plastic

Plastic is widely spread and used for the raw material cost considerations, its good characteristics and the simple product shaping. Plastic properties and the features allow you to create a wider range of formats and products, in addition to plastic formation is efficient and conditionally cheap. Useful and cost-effective to replace metal with plastics that are used in various industries.
Properties of plastics and machining features are highly dependent on the properties of polymers, and they are very different.


Acryl ( PMMA)

Premium Acryl glass made from polymethylmethacrylate (PMMA). Acryl is a rigid, transparent plastic, reminding normal glass, but its characteristics are significantly superior. Acryl is unbreakable and many times stronger than glass, which makes it much more resistant to shock and of course safe to use in situations where the glass would be dangerous to use. Acrylic also a better insulator than glass and potentially much more economical. Another big advantage is that it is twice lighter than glass, making it work with acryl incomparably easier. Acryl is used in manufacturing a wide variety of products, such as shower cab doors, bathtubs casings, windows, various furniture items and etc. Due a smooth and glossy surface it is easy to maintain. A common high-quality Acryl contains polycast (acrylic resin), Lucite (thermoplastic acrylic resin) and organic glass.

There are two basic types of Acryl: pressed and the molten cells. Pressed or “continuous casting” acryl is made from cheaper materials and may contain various impurities, so it is softer and more easily scratched and damaged.

Material properties:
Very good transparency – 92% -95%;
Good resistance in all weather conditions;
Durable to shock and mechanical impact;
Non – toxic.


Polyvinylchloride ( PVC )

PVC is widely used plastic. It is a polymer with good chemical resistance properties (excluding solvents), low flammability class, UV ray resistant. Used in design, equipment, consumer goods, chemicals containers and various mechanical parts manufacturing. Globally, more than 50% of PVC manufactured is used in construction. PVC as a building material is an inexpensive and very convenient for installation.

The composition of PVC is :
PVC ( polivinilchloridas ) cheminis chloro, anglies, vandenilio junginys, paprastai vadinamas tiesiog plastiku. PVC sudedamosios dalys kilusios iš natūralių žaliavų – naftos arba dujų ir valgomosios druskos. PVC yra chemiškai stabilus ir nepavojingas žmogaus sveikatai.

Wood

Chipboard panels can be classified according manufacturing process, number of layers used, particle density, surface type.
Single layer plate has a solid structure, usually a low particle density, and all particles are the same size. The surface of this type of plate is rough. These boards are mainly used for construction purposes.
Recently, the furniture industry is increasingly replacing conventional particle boards medium density fibreboard (Medium Density FIBERBOARD – MDF). MDF – is made from wood fiber and binding material on impact of high temperature and high pressure. This provides a better surface strength and flexibility. These panels are well machined: easy to produce a variety of forms and so on. Due to these characteristics, the MDF is widely used in furniture production.
Multilayer panel properties similar to MDF three-layer properties, but the multilayer panel due to its high density core is more flexible and durable.

Dialux – especially high-gloss panel, coated with PET film. Made by MDF base.Has the following characteristics:

  • scratch-resistant;
  • non dusty;
  • waterproof and stain resistant (easy to clean, color remains unchanged);
  • environmentally friendly ( contains no PVC ) .

Plywood board – wood product made from glued together several sheets of wood veneer. Plywood used for furniture, container production, construction, interior decoration and other fields.
