These alloys allow for the creation of expanded metal with exceptional durability, resistance to corrosive environments, and stability under thermal stress, making them suitable for use in filtration, shielding, and architectural applications. Nickel alloys’ specific properties ensure that expanded metals produced with these materials meet stringent performance and longevity requirements.
