Invar 42 Rod 1/2 inch FAQs

Q1: What are the key material properties of Invar 42 Rod 1/2 inch?

A1: Invar 42 is an iron-nickel alloy with around 42% nickel content, prized for its consistently low coefficient of thermal expansion (approximately 3.8 × 10^-6 /K from 20°C to 200°C). It offers excellent dimensional stability, which is critical in precision instrumentation and electronic applications. With a typical density of 8.1 g/cm³ and moderate strength, Invar 42 provides reliable performance under varying temperatures and thermal stress.

Q2: How can an Invar 42 Rod 1/2 inch be processed or fabricated?

A2: Invar 42 Rod 1/2 inch can be processed by conventional methods such as turning, milling, and drilling, though cutting speeds are often lower due to the alloy’s toughness. Preheating may be used for hot working, and forging typically occurs between 1 000°C and 1 200°C. Post-fabrication annealing at around 800°C helps relieve residual stresses and stabilise the alloy’s low-expansion characteristics.

Q3: Which quality standards and certifications apply to Invar 42 Rod 1/2 inch?

A3: Invar 42 products often conform to recognised material specifications like ASTM F1684 or equivalent standards that govern chemical composition, mechanical properties, and dimensional tolerances. Manufacturers may also comply with ISO 9001 for quality management and AS9100 for aerospace applications. In addition, many suppliers conduct stringent inspection and testing, including ultrasonic examinations, to ensure that each 1/2 inch rod meets required specifications for dimensional accuracy and material integrity.
