Buy at affordable prices from the manufacturers of a circle, wire or pipe, which are made of precision alloy grades 42H and 42 offers the company AvecGlob. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

Alloy 42H belongs to the group of precision alloys that have a specified value of the coefficient of thermal linear expansion. A similar alloy 42 possesses a lower nickel content.

Such alloys are necessary for the successful design and installation of high-temperature equipment, when it is important to consider the thermal expansion and be able to calculate the expected expansion volume.

Alloys with controlled expansion characteristics are used for a wide range of applications where the thermal change in the size of the metal must be taken into account in the design of the parts. As a rule, these alloys expand with heating and contract with cooling.

There are three main types of such alloys:

With a low thermal expansion, it is predominantly iron-

nickel alloys having minimum values of the expansion coefficients in certain temperature ranges. They are commonly used in electronic devices, instrumentation and thermostats;

With a given extension, these alloys have roughly the same expansion coefficients as the glasses and ceramics commonly used in the electronics industry;

Alloys with high thermal expansion, which are used primarily in thermostats.

The chemical composition of alloy 42H, which meets the standards of GOST 10994−74, is given in the table (numerical data — in percent):

Avec Glob Company sells wire, circle and pipe of 42H and 42 precision alloys at a cost-effective price, with a specified coefficient of thermal linear expansion. Supplier provides prompt delivery of products to any point set by the client.
