Invar 52 Plate Annealed FAQs

Q1: What are the key material properties of Invar 52 Plate Annealed?

A1: Invar 52 Plate Annealed is a nickel-iron alloy known for a near-zero coefficient of thermal expansion at specific temperature ranges, typically around 52% nickel. It offers excellent dimensional stability, high strength, and good ductility after appropriate heat treatment. Its magnetic permeability is relatively high, making it suitable for electromagnetic shielding applications. The annealing process refines grain structure, resulting in mechanical and thermal stability.

Q2: How is Invar 52 Plate Annealed typically processed or fabricated to maintain its dimensional stability properties?

A2: Typically, Invar 52 Plate Annealed can be machined with standard carbide tools, though lower feed rates and speeds are often recommended due to its toughness. Cold working such as stamping or drawing must be conducted carefully to minimise stress. A final annealing step at controlled temperatures helps restore ductility and dimensional accuracy. Welding is possible using low-heat input techniques and compatible filler metals.

Q3: Which quality standards and certifications apply to Invar 52 Plate Annealed?

A3: Invar 52 Plate Annealed frequently adheres to ASTM standards, such as ASTM F1684, ensuring consistent composition and mechanical properties. Aerospace or automotive applications may require additional specifications like AMS or MIL standards. Manufacturers typically comply with ISO 9001 or AS9100 for quality management. Material test certificates often provide traceability, verifying chemical analysis, tensile data, and hardness. Third-party certifications may also be obtained based on application requirements.
