Níquel 200
Nickel 200 is a 99.6% pure wrought nickel alloy. It offers excellent mechanical properties and resistance to many corrosive environments. It is best known for its exceptional resistance to caustic alkalis up to 600°F (315°C).
- Formas comuns: Plate, Sheet, Strip, Pipe, Tube, Round Bar, Wire.
- Caraterística principal: Outstanding resistance to caustic soda (sodium hydroxide).
- Physical Prop: High electrical and thermal conductivity; ferromagnetic.
- Temperature Limit: Recommended for service below 600°F (315°C).
Nickel 200 is the standard material of choice for environments containing caustic alkalis. Its high purity also gives it unique physical properties not found in other nickel alloys, making it valuable for electronic and food processing applications.
Resistência aos cáusticos
Excellent resistance to all concentrations of sodium hydroxide (caustic soda) at temperatures up to 600°F, forming a protective oxide film.
High Conductivity
Unlike alloyed materials (like Inconel or Monel), pure Nickel 200 retains very high thermal and electrical conductivity.
Product Purity
With a minimum nickel content of 99.0%, it is ideal for applications where product contamination must be minimized, such as food and synthetic fiber processing.
