The family of precision materials has very useful qualities that are actively used in many critical areas of modern production. High performance characteristics of such alloys are due primarily to their precise chemical composition, without the content of random impurities that can reduce the dignity of the material. Good performance of such raw materials is associated with high quality of production and strict observance of technological discipline in the smelting process.
Characteristics of the alloy 49KF
The alloy 49KF refers to a magnetically soft type, which fully explains its fast magnetic saturation even by low-strength fields, as well as a high index of magnetostriction ability. In general, alloys with these qualities contain in their composition, in addition to iron, a certain amount of cobalt and nickel and other elements with similar properties. Due to such characteristics and special quality of manufacturing, such raw materials are used in especially important areas of industry such as electrical engineering, production of measuring equipment, computers and much more.
Application
Most often, the 49KF alloy, along with other precision materials, is used in the manufacture of transformers of various types and dimensions. Also, such raw materials are actively used in the field of precision machine-tool construction or in the manufacture of television equipment. Magnetic pipelines, made of high-quality material, have proven themselves in work in aggressive environments (such as sea water). Precise instrumentation or the manufacture of sensitive antennas, laser equipment, or the metrology industry equally need such high-quality and reliable raw materials.

Features of welding
| The alloy has limitations on weldability | The welding process requires some preliminary preparation (warming the contacting surfaces to one hundred and one hundred and twenty degrees and subsequent heat treatment of the seam zone) |
| The alloy has no weld constraints | No preliminary preparation required |
| Material difficult to weld | It is necessary to warm the contacting surfaces to two hundred or three hundred degrees, the subsequent annealing and heat treatment after the end of the welding process |
