Invar 36 is a nickel-iron alloy made up of about 36% nickel and 64% iron. This unique blend gives it an incredibly low coefficient of thermal expansion, roughly 1.2 × 10⁻⁶ /°C, which is perfect for applications sensitive to temperature changes. The alloy boasts a tensile strength ranging from 480 to 620 MPa, a yield strength between 240 and 370 MPa, along with good ductility and toughness. Invar 36 Pipes maintain their shape even when temperatures fluctuate and show moderate resistance to corrosion in mild environments. Their blend of mechanical strength and thermal stability makes them ideal for precision engineering, cryogenics, and structural applications.
