The use of precision alloys in communication equipment

Modern communication technologies place high demands on materials used in the manufacture of communication equipment. Temperature changes, the need for high accuracy and stability of operation — all this requires the use of special steels and alloys. One of them is precision alloys — metal materials with extremely precise chemical composition and predictable physical properties. In this article, we will explain why precision alloys are unique, where they are used and what grades are produced at PZPS.

What are precision alloys

Precision alloys are a special class of metal materials that are developed and manufactured with high accuracy in composition and properties. Their task is to ensure stable and reliable operation in conditions where even the slightest deviation from the norm can lead to failures or a decrease in the efficiency of devices.

The main features of precision alloys:

  • High purity of the composition — the content of alloying elements is strictly controlled, and the quantity harmful contaminants is minimized, since even a slight deviation from the regulated composition can lead to a change in the physical properties of the alloy.
  • Specific properties — precision alloys may have unique magnetic, elastic, and electrical characteristics necessary for solving specific problems.
  • Operational stability — these alloys retain their properties in a wide range of operating conditions, including high temperatures and pressure.

It is these qualities that make precision alloys indispensable in the production of communication components.

Where and how are precision alloys used in communications

Communication devices include not only mobile phones or wireless radios, but also complex data transmission systems, satellite communications, and telecommunications infrastructure. These devices use materials that can operate at high frequencies, in small packages and at different temperatures.

These are the main applications of precision alloys in communication equipment:

  • Inductors and transformers — precision alloys increase the accuracy and stability of equipment, improve the efficiency of signal transmission.
  • Magnetic cores — used in devices where electromagnetic parameters are important, for example, in radio frequency amplifiers and filters.
  • High-Frequency Technology Components — resonators, filters, dampers and other elements in which critically low resistance, minimal losses and high accuracy are important.

These areas require materials with not just good, but ideal parameters that will not change under different operating conditions. That is why precision alloys are the most preferred option in the manufacture of switching equipment.

The main types of precision alloys in communication equipment

There are many types of precision alloys, each of which is optimal for a particular application. Below we'll look at two of the most popular groups.

Soft magnetic alloys

These materials have high magnetic permeability and low coercive force, so they are easily magnetized and demagnetized without loss. Soft magnetic alloys they react quickly to changes in the flow of magnetic lines of force and retain minimal residual magnetic properties after removing the external magnetic field. This makes the presented materials ideal for all types of transformers and inductive elements.

Application examples:

  • Transformer cores and inductors — the use of soft magnetic materials makes it possible to effectively convert and transmit electrical signals.
  • Elements of high-frequency equipment — these alloys are used in the manufacture of magnetic cores and magnetic cores to concentrate magnetic flux and improve the characteristics of high-frequency devices.
  • Magnetic screens, sensors and other electronic components — soft magnetic alloys are used in devices that require high magnetic permeability and low energy loss.

The following grades of soft magnetic alloys are produced at PZPS:

  • 49K2FA-VI — an alloy with high magnetic permeability and low losses, ideal for small-sized transformers;
  • 27KH — has a low coercive force and is used in critical products;
  • 50N, 50NP — widely used in radio engineering and telecommunications.
  • 79NM, 80NM, 81NMA — nickel-iron alloys with high magnetic accuracy are used in microwave devices.

These materials make it possible to increase the sensitivity and stability of electronic components.

Alloys with a predetermined linear expansion temperature coefficient (TKLR)

For devices operating at variable temperatures, it is important that materials do not deform when heated or cooled. Alloys with a given TCLR retain their dimensions and geometry, preventing stresses and cracks caused by changes in temperature.

Examples of the use of alloys with a given TCLR in communication equipment:

  • High-precision electronics components — used in the manufacture of printed circuit boards, capacitors and other parts for which it is important to maintain geometric parameters during temperature fluctuations, as well as for connection with other materials, such as glass.
  • Optical systems — in optical modules and laser systems used in fiber-optic communication lines (FIBER-optic communication lines), precision alloys help maintain accurate focusing and alignment of components.
  • Hermetic electronic module enclosures — used for the manufacture of housings and fittings, ensuring the tightness of electronic components and their protection from external influences.

Brands produced by PZPS:

  • 29NK — classic material for bonding with borosilicate glass, ideal for sealed enclosures;
  • 33NK — well compatible with ceramic elements, used in optical and ultra-high-frequency devices;
  • 36N, 42N — provide ultra-low TCLR and are used in microassemblies and precision mechanical elements.

Due to their dimensional stability, these alloys ensure high accuracy in adjusting and aligning components, especially in fiber-optic communication lines.

Other precision alloys produced by PZPS

In addition to soft magnetically and thermostable alloys, PZPS also offers other materials that are in demand in electronics and radio engineering:

  • Alloys with specified elastic properties:
  • Alloys with high electrical resistance:
    • X15YU5, X23U5, X23YU5T — resistant to overheating, used in heating elements and precision resistors;
    • X20N80N, X15N60N — stable at high temperatures, used in DC circuits and thermoregulatory elements.

These materials make it possible to create reliable and durable components that are resistant to environmental influences. Thanks to strict quality control at all stages of production, from melting to rolling, PZPS products meets international standards, has a precise chemical composition and is characterized by stable physical and mechanical properties.
