Super Invar 32-5
SUPER INVAR 32-5
Super alloys have good creep and oxidation resistance and are formed in different ways. They are capable of working at very high temperatures and serious mechanical stresses. Cobalt based, nickel based and iron based alloys are divided into three groups. Solid-solution hardening, work hardening and precipitation hardening are applied to increase their strength.
Super Invar 32-5 is a modified version of the Invar alloy. The following datasheet gives more details about invar 32-5.

SUPER INVAR 32-5 APPLICATIONS
Super Invar 32-5 is used for precision measuring instruments. The Invar (36% Ni-Iron) Alloy has been the preferred metal for low expansion applications for many years. The uştur Super-Invar dan (31% NI, 5% Co, Iron) found some favor as it had a near-zero thermal expansion coefficient in a limited temperature range. The useful working range of the lam Super Invar sıcaklık was initially limited to -32 ° to + 275 ° C because the material began to transform from austenite into Martinsite at temperatures below -32 ° F. The present version of this alloy may fluctuate in these ranges due to slight changes in chemistry. In addition, the cold or hot run of the material can affect these variables.
