Nickel-iron alloy Advantage

1. 1. Corrosion resistance: Iron-nickel alloy has excellent corrosion resistance and can resist the erosion of corrosive media such as strong acids and alkalis. Therefore, it is widely used in chemical industry, petroleum, marine engineering and other fields.
2. 2. High strength and high toughness: Iron-nickel alloy has excellent strength and toughness and can be used to manufacture high-load and high-stress parts, such as aerospace engines, vehicle engines, rocket engines, etc.
3. 3. High temperature resistance: Iron-nickel alloy has good heat resistance under high temperature conditions and can maintain its strength and toughness at high temperatures. Therefore, it is widely used in aviation, rockets, nuclear power plants and other fields.
4. 4. Low magnetic permeability: Iron-nickel alloy has low magnetic permeability and can resist the interference and influence of electromagnetic waves, so it is widely used in electronic communications, precision instruments and other fields.
