Precision alloys combine a sufficiently large group of highly alloyed materials with high precision of manufacture and excellent quality of final processing. The chemical composition of this raw material is regulated by normative documents of the state level and is characterized by a high degree of constancy and complete absence of random impurities. Most alloys of this type have many unique properties, such as high thermal conductivity, fixed linear expansion, magnetic properties, resistance to elastic deformations.

The characteristics of the alloy 45NHT

The 45HXT alloy has sufficiently high elastic properties. Due to this, such material is actively used in the production of high-quality semi-finished products, which are used to manufacture a variety of details of a complex profile of increased elasticity. Various suspensions, hygroscopes, liquid density meters, rotors — these are just a small part of the production made from an alloy of a similar brand. A successful and balanced combination of chemical elements such as manganese, aluminum, chromium, titanium, nickel in the composition of raw materials explains the unique qualities of this alloy. Currently, a wide range of semi-finished products with 45NHT marking, from tapes, sheets and wire to profiled products of a complex profile, is being widely sold. Such a variety of semi-finished products will help everyone to choose the right option for solving specific production problems.
