Alloys with a given TKLR
Are you interested in alloys with specified values of the coefficient of thermal expansion (TKLR) from the supplier — the company AvecGlob? Here you will find the necessary information on this topic
Buy at various prices from the manufacturer of various grades of alloys that have specified values of the coefficient of temperature expansion, suggests the company AvecGlob. The supplier guarantees the prompt delivery of products to any address specified by the consumer.
General information
The coefficient of thermal expansion, usually represented by the symbol α, is a measure of the change in the length of the material as a reaction to a change in its temperature. Calculation of the coefficient is usually performed in comparison with the same index of the alloy at a temperature of 20 ° C. The coefficient of thermal expansion of the material is not constant and usually increases at higher temperatures.
The values of the coefficient may vary depending on a number of factors, including the type of alloy and the mode of its heat treatment.
Alloys with a specified temperature coefficient of linear expansion (TKLR) are intensively used in such industries as instrument making, machine building, electronics, measuring technology, military space industries. Of these materials, reference tools and bar-measures are produced. The practical value of such alloys determines the stability of their dimensions in a given temperature range.
Avec Glob Company sells various grades of alloys at affordable prices, differing in the certain value of TKLR, both domestic and foreign. The supplier ensures the prompt shipment of products to any point set by the client.
