Nickle Plated Single Wire

Nickle plated single wire A method of plating a layer of nickel on a metal or certain non-metal by electrolysis or chemical methods, called nickel plating. Nickel plating includes electroplating nickel and electroless nickel plating. Nickel plating is in the electrolyte composed of nickel salt (called the main salt), conductive salt, pH buffer, wetting agent, the anode with metal nickel, cathode for plating, through direct current, deposited on the cathode (plating) on a layer of uniform, dense nickel coating. Bright nickel is obtained from the plating solution with brightener, and dark nickel is obtained from the electrolyte without brightener. Electroless plating, also known as electroless plating, can also be called Autocatalytic plating [1]. The specific process refers to the process in which metal ions in aqueous solution are reduced by reducing agent under certain conditions and precipitated to the surface of solid substrate. ASTM B374(ASTM, American Society for Materials and Testing) defines Autocatalytic plating is "deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloybeing deposited". This process is different from replacement plating in that the coating can be continuously thickened [2], and the plating group itself also has catalytic ability.

Characteristics, properties and uses of nickel plating:

1, the stability of the electroplated nickel layer in the air is very high, because the metal nickel has a strong passivation ability, can quickly generate an extremely thin passivation film on the surface, can resist the corrosion of the atmosphere, alkali and some acids.

2, electroplating nickel crystal is extremely small, and has excellent polishing properties. The polished nickel coating can obtain a mirror-like luster, while maintaining its luster in the atmosphere for a long time. Therefore, electroplating is often used for decoration.

3, the hardness of the nickel coating is relatively high, which can improve the wear resistance of the surface of the product, and the nickel plating layer is commonly used in the printing industry to improve the hardness of the lead surface. Due to the high chemical stability of metal nickel, some chemical equipment is also commonly used with thicker coating to prevent corrosion by the medium. Nickel plating layer is also widely used in functional aspects, such as repairing worn, corroded parts, using brush plating technology for local plating. The electroforming process is used to manufacture electroforming plates, record molds and other molds for the printing industry. The thick nickel plating layer has good wear resistance and can be used as a wear-resistant coating. Especially in recent years, composite plating has been developed, which can deposit composite nickel coating with wear-resistant particles, and its hardness and wear resistance are higher than that of nickel plating. If graphite or fluorinated inks are used as dispersed particles, the nickel-graphite or nickel-fluorinated inks composite coatings obtained have good self-lubricating properties and can be used as lubricating coatings. Black nickel coating is also widely used as the coating of optical instruments or decorative coating.

4, the application of nickel plating is very wide, can be used as a protective decorative coating, on the surface of steel, zinc die casting, aluminum alloy and copper alloy, to protect the base material from corrosion or play a bright decorative role; It is also often used as an intermediate coating of other coatings, on which a thin layer of chromium is plated, or a layer of imitation gold is plated with better corrosion resistance and more beautiful appearance. In terms of functional applications, nickel plating on parts in special industries is about 1~3mm thick, which can achieve the purpose of repair. Especially in the continuous casting mold, electronic component surface mold, alloy die-casting mold, complex shape aerospace engine components and micro electronic components manufacturing more and more widely.

5, in electroplating, because electroplating nickel has many excellent properties, its processing volume is second only to electrogalvanizing, and its consumption accounts for about 10% of the total nickel production.

Can be processed, derived from a variety of cables, such as power cables, communication cables, control cables, special cables, these cables are widely used in power, railway, communications, aviation, medical, transportation, construction, ships and other industries.

Electroless nickel plating features, properties, uses:

1, thickness uniformity Uniform thickness and good plating ability is a major feature of electroless nickel plating, but also one of the reasons for wide application, electroless nickel plating to avoid the plating due to uneven current distribution caused by uneven thickness. During electroless plating, as long as the surface of the part is in contact with the plating solution, the components consumed in the plating solution can be supplemented in time, and the coating thickness of the plating part is basically the same, even if the groove, gap, and blind hole are also the same.

2, the plating will not be hydrogen infiltration, no hydrogen embrittlement, no need to remove hydrogen after electroless nickel plating.

3, the functions of many materials and parts, such as corrosion resistance and high temperature oxidation resistance, are better than nickel plating.

4, can be deposited on the surface of various materials, such as: steel nickel base alloy, zinc base alloy, aluminum alloy, glass, ceramics, plastics, semiconductors and other materials on the surface, so as to improve the performance of these materials to create conditions.

5, do not need the general electroplating required DC motor or control equipment.

6, the heat treatment temperature is low, as long as it is below 400℃ after different holding time, different corrosion resistance and wear resistance can be obtained, therefore, it is especially suitable for the functional coating of parts with complex shapes and surface requirements for wear and corrosion resistance

Quality and control standards meet BS EN13601 ASTM B355, GB/T 11019-2021 nickel-plated round copper wire.

During the transportation of the product, take protective measures such as moisture proof (wrap the product with four square plastic bags on rainy days), anti-bruise (fix the product with a wooden frame to prevent the product from rolling and bruise), and each delivery is delivered at the scheduled time.

After the completion of the production of tin copper alloy must be strictly in accordance with the customer and industry standards for packaging, storage, handling and transportation, to ensure that the product is not damp, not hurt.

Storage conditions of finished products at ambient temperature ≤35℃, relative humidity ≤65%. (The storage life of the conductor must meet the requirements of temperature and humidity)
