Nickel Etching
What is Nickel Chemical Etching
Nickel chemical etching is a precise method for selectively removing material from nickel substrates using chemical solutions. The process involves immersing the substrate into an etchant solution, where chemicals dissolve nickel from exposed areas, leaving behind intricate patterns or designs. Control factors like etchant composition, temperature, and agitation ensure uniform material removal.
Widely utilized across industries like electronics and aerospace, it's ideal for MEMS, electronic components, and precision parts. Compared to traditional machining, it offers advantages such as precise geometry, cost-effectiveness for small to medium production runs, and the absence of mechanical stresses or burrs.
What's the characteristics of nickel materal ?
- Nickel is a silver-white metal with good mechanical strength and ductility. It is insoluble in water and has strong corrosion resistance to acids and alkalis, but it is easily soluble in dilute nitric acid and aqua regia. High-temperature resistance, melting point 1455 °C, boiling point 2730 °C. The density is 8.902g/cm³.
- Nickel can create a dense oxide film that can be formed on the surface of itself. The color becomes black, which can prevent the body metal from continuing to oxidize.
- Nickel is a ferromagnetic material with low chemical activity, strong-corrosion resistance, high strength, good toughness, and excellent processing performance
Benefits of Nickel Etching
Lower difficulty and cost
The nickel parts with complex shapes can be processed easily, such as a very thin nickel gride is a very typical example. Through the use of etching technology, the difficulty of forming and processing costs can be reduced.
Stable physical properties
Nickel etching process will not change the physical properties of metal materials such as hardness, strength, and formability.
Ensure the integrity of materials
Nickel metal materials are easy to break during the stamping process. They are easy to produce curling burrs, which affect the assembly of the product, and nickel etching can ensure that these materials are intact.
High Precision
If your nickel components are very thin (thickness between 0.03mm-1mm), using other processes may cause components deformation. However, nickel etching can ensure that the components are not deformed. Generally, the thinner the nickel components, the higher the precision.
