What are the thermal properties of invar 36


What is Invar 36?

Invar 36® is an iron-based alloy with 36 % nickel. Invar 36® also has excellent mechanical properties and a low tendency to fatigue in a cryogenic environment. Invar 36 (Nilo, Nilvar, Permalloy D, FeNi36, and 64FeNi) is a nickel-iron alloy notable for its extremely low thermal expansion. Invar is an alloy of iron that expands very little when heated; it contains 64% iron and 36 percent nickel. Invar was formerly used for absolute standards of length measurement and is now used for surveying tapes, watches, and other temperature-sensitive devices. Invar requires special machining processes that include stress-relieving heat treatments for a consistent CTE in a precision machined part to ensure CTE and dimensional stability in service.


What is the disadvantage of Invar36?

Invar material is challenging to machine due to its high strength and hardness. It requires specialized machining techniques and tools, which can add to the overall manufacturing costs. Invar 36® is effective in extreme temperatures ranging from -150°C (-238°F) up to 260°C (500°F), while Invar 42®—or SuperInvar® — maintains nearly constant dimensions in temperatures ranging from -32°C (-25.6F) to 275°C (527°F). Invar® is used primarily for controlled expansion and magnetic applications. It is strong, tough, pliable, and highly resistant to corrosion. Invar® is always magnetic in the temperature range, exhibiting low expansion characteristics. Invar 36 alloys are soft like Type 304 and Type 316 austenitic stainless steels; the free-cut variation, particularly machines, are similar to those two stainless grades. They all have the same high work-hardening rate, which requires care in machining.


What are the thermal properties of invar 36?

SSC INVAR 36 nickel alloy plate is an austenitic nickel-iron alloy containing 36% nickel. Invar 36 (FeNi36) is a nickel-iron, low-expansion alloy with a near-zero thermal expansion rate and can maintain almost constant dimensions from cryogenic temperatures to 260°C. It has become a popular choice when it comes to composite material manufacturing. A general expectation for Invar materials is that magnetism causes a negative thermal expansion coefficient to counteract a positive thermal expansion of the lattice. This magneto-volume effect arises from the rich magnetic landscape of iron and its dependence on the volume and local atomic configurations. Due to this, demand has grown for aluminum-clad invar alloy wire, which has a thick corrosion resistance layer, high strength, and good electric conductivity, reducing transmission loss and CO2 emissions.
