Circle, wire, pipe 42НХТЮ - Пернифер 42

Buy at affordable prices from the manufacturers of a circle, wire or pipe, which are made of precision alloy 42HXTU and Permafer 42 brands is offered by AvecGlob. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

The alloy 42НХТЮ belongs to the group of precision alloys that have specified elasticity indices. Abroad, the alloy of this purpose is produced under the trade mark Permafer 42. These materials are intended for use in elastic sensitive elements operating at a temperature of no higher than 100 0 С.

These alloys are based on an iron-nickel base, additionally doped with chromium, titanium and aluminum, which have low thermal expansion characteristics in a certain temperature range, which makes them particularly suitable for use in glass and ceramic seals. The considered alloys are also used in various electronic components and lead protective screens / shells.

The key features of 42HXTU and Permafer 42 alloys is the consistency of the coefficients of thermal expansion with such substances as silicon, ceramic materials, aluminum oxide, and also vitreous compounds. The main application of these alloys is semiconductor packages, electronic tubes, electronic CRT guns, automotive and industrial lamps.

The chemical composition of the alloy 42НХТЮ, which meets the technical requirements of GOST 10994−74, is given in the table (numerical data — in percent, iron — rest):

C Si Mn Ni S P Cr Ti Al
Not more than 0.05 0.5… 0.8 0.5… 0.8 41.5… 43.5 Not more than 0.02 Not more than 0.02 5.3… 5.9 2.4… 3 0.5… 1

AvekGlO sells wire, a circle and a tube of precision alloys 42NXTU and Permafer 42 at economically favorable prices, with specified elastic parameters. Supplier provides prompt delivery of products to any point set by the client.
