J0-1 Ultra-Low PhosphorusElectroless Nickel

▪ JO Ultra-Low Phosphorus Electroless Nickel is an innovative electroless nickel plating process that utilizes hypophosphite as the reducing agent. This process is free from lead and cadmium compounds, making it fully compliant with RoHS standards and environmentally friendly. The plating is characterized by its ultra-low phosphorus content, which is consistently controlled within the range of 1-3% by weight. This unique composition results in a coating with exceptional mechanical properties, making it suitable for a wide range of industrial applications.

▪ One of the standout features of JO Ultra-Low Phosphorus Electroless Nickel is its high coating hardness, which can reach 700-850 HV0.1 in the as-plated condition. After heat treatment, the hardness can be further enhanced to an impressive 1000-1100 HV0.1, making it ideal for applications requiring extreme wear resistance and durability. The process is known for its excellent stability, long bath life, and high tolerance to impurities, ensuring consistent performance even after 7-8 cycles of operation on aluminum substrates. This stability also contributes to maintaining a high deposition rate throughout the plating process, without significant degradation over time.

▪ The coating produced by JO Ultra-Low Phosphorus Electroless Nickel is bright and uniform, with a smooth surface finish that meets the highest aesthetic and functional standards. The process exhibits exceptional adhesion to aluminum substrates, with no issues of foaming or peeling, even under demanding conditions. This strong bonding capability ensures that the coating remains intact and provides long-lasting protection to the substrate. The bright and flawless appearance of the coating makes it suitable for both decorative and functional applications, particularly in industries such as automotive, electronics, and aerospace, where surface quality and performance are critical.

▪ In addition to its mechanical and aesthetic properties, JO Ultra-Low Phosphorus Electroless Nickel offers excellent corrosion resistance, particularly in environments where exposure to moisture, chemicals, or abrasion is a concern. The ultra-low phosphorus content contributes to the formation of a dense and uniform coating structure, which acts as an effective barrier against corrosive agents. This makes the process highly suitable for components used in harsh operating conditions, such as engine parts, hydraulic systems, and electronic connectors.

▪ The process operates at moderate temperatures, typically between 85-90°C, and is compatible with a wide range of substrates, including aluminum alloys, steel, stainless steel, and copper alloys. Its versatility and ease of operation make it a cost-effective solution for both rack plating and barrel plating applications. Furthermore, the process is compatible with post-plating treatments, such as heat treatment and passivation, which can further enhance the coating's properties and extend its service life.

▪ In summary, JO Ultra-Low Phosphorus Electroless Nickel is a highly advanced plating process that combines ultra-low phosphorus content, high hardness, excellent adhesion, and superior corrosion resistance. Its compliance with RoHS standards, long bath life, and high impurity tolerance make it an environmentally friendly and economically viable solution for modern manufacturing. Whether used for functional performance or decorative finishes, this process delivers consistent, high-quality results that meet the stringent demands of today's industries.
