Nickel Sulfamate
For companies seeking an effective electroforming option, Gleco offers MIL-P-27418, AMS 2424, and AMS-QQ-N-290 nickel sulfamate plating. A subset of nickel plating, this process is primarily used for depositing functional coatings for low-stress applications.
While Nickel Sulfamate has a premium price point, this cost can be offset by the high deposition rates and deposit properties (such as requiring no additional agents). Because nickel sulfamate produces a compressively stressed deposit, it is also used for crimping or flexing applications and joining applications involving soldering, brazing, or laser welding.
What is Nickel Sulfamate?
Typical nickel sulfamate compounds contain three elements:
- Nickel Sulphamate
- Nickel Chloride
- Boric Acid
Chloride has a pronounced effect on the stress of a nickel sulfamate solution, and low-chloride concentrations are ideal for low-stress applications. Alternatively, nickel bromide may be substituted to reduce even more stress.
Nickel sulfamate consists of a 99.9% pure nickel deposit, making it better suited for mechanical, engineering, and other functional manufacturing applications. It can be used on various materials, including chilled irons, copper and brass, aluminum alloys, steel alloys, and stainless steel. It can also be used as a reducing agent for flashing on steel surfaces and as a blackening agent for brass and zinc finishes.
When combined with a thin chromium overlay, nickel sulfamate is the most effective option for preserving metal finishes in highly corrosive environments.
Benefits of Nickel Sulfamate Plating
- Most machinable nickel-based electroplating process
- Affordability
- Resistance to high temperatures
- High tensile strength
- Superior ductility and elongation
- No stress cracking or deformation
One of the key advantages of sulphamate nickel solutions is their higher solubility, which makes it possible to use higher nickel concentrations while still operating at very high current densities.
