Invar 36 Rod 5/8 inch FAQs

Q1: What are the key material properties of Invar 36 Rod 5/8 inch?

A1: Composed of approximately 36% nickel and 64% iron, Invar 36 Rod 5/8 inch is prized for its exceptionally low coefficient of thermal expansion, roughly 1.2 x 10^-6 per °C from 20 to 100°C. It offers excellent dimensional stability, making it ideal for applications requiring minimal thermal distortion, such as precision instruments. In addition, it maintains good toughness and strength, with a typical yield strength around 240 MPa.

Q2: How can Invar 36 Rod 5/8 inch be processed or fabricated?

A2: Invar 36 can be hot or cold worked using conventional processes, though it requires care due to its toughness and low thermal conductivity. For forging, temperatures generally range from 870°C to 1 150°C. Machining demands sharp tools and moderate cutting speeds, while welding is achievable with common methods such as TIG or MIG, provided preheating and post-weld heat treatments minimise stress. Proper annealing may restore optimal dimensional stability.

Q3: Which quality standards and certifications apply to Invar 36 Rod 5/8 inch?

A3: Invar 36 rods generally align with ASTM F1684 or AMS I-230, ensuring composition and mechanical property requirements. Many manufacturers also maintain ISO 9001 certification to uphold consistent quality management. When used in aerospace or specialised engineering contexts, NADCAP approvals for specific processes may apply. Additionally, documentation such as material test reports verifies chemical composition, mechanical properties, and compliance with industry standards for safe, traceable application.
