Palladium Nickel Alloy

Palladium Nickel Alloy particles are alloy particles of palladium and nickel, silver grey in colour, with good hardness, corrosion resistance, thermal stability and specific electrical properties, which are promising for applications in many fields, such as electronics and chemicals.

Characteristics

Appearance: usually silver-grey granules with a high metallic luster.

Melting point: generally around 1237°C (at 60% palladium content), it has a high melting point, which allows it to maintain good stability at high temperatures.

Density: Between the densities of palladium and nickel, it is relatively dense, which gives the particles a certain weight.

Hardness: Higher hardness than pure palladium particles. The addition of nickel increases the hardness of the alloy, making it more resistant to external forces and less prone to deformation or wear during processing and use.

Oxidation resistance: Palladium itself has good oxidation resistance, and when alloyed with nickel, the oxidation resistance is also relatively good, but oxidation reactions may still occur under certain conditions (e.g. high temperatures, specific chemical environments).

Corrosion resistance: It has good corrosion resistance and is stable in a variety of corrosive media. For example, in some acidic and alkaline environments, palladium-nickel alloy particles can maintain good chemical stability and are not easily corroded.

Hydrogen adsorption: alloys containing more than 5% nickel are saturated with hydrogen to produce only the а phase, which has a certain adsorption capacity for hydrogen, a characteristic that makes them potentially valuable in hydrogen-related applications, such as as some materials in the field of hydrogen energy.

Electrical properties: good electrical properties, the resistivity varies depending on the ratio of palladium to nickel, but in general it can be used as an electrical contact material in the electronics industry, for example.

Processing properties: It has good processing properties and can be prepared into granules by various methods, such as atomisation and electrolysis. And the prepared particles are more uniform in size and regular in shape, which is convenient for subsequent processing and use.

Application

Electronic industry:

Electrical contact materials: Palladium nickel alloy particles can be used to manufacture electrical contact parts in various electronic devices, such as switches, relays, connectors and so on. Their good electrical conductivity, hardness and corrosion resistance ensure the stability and reliability of electrical contacts and reduce contact resistance and signal transmission losses.

Potentiometer winding material: In potentiometers, palladium nickel alloy particles can be used as a winding material, using its resistance characteristics to adjust the resistance value in the circuit, to achieve precise control of current, voltage and other parameters.

Catalytic field:

Catalysts for chemical reactions: Palladium nickel particles have excellent catalytic properties in many chemical reactions. For example, in organic synthesis reaction, it can be used to catalyse hydrogenation, dehydrogenation, oxidation and other reactions, to improve the reaction rate and selectivity, and reduce the harshness of the reaction conditions. Meanwhile, in the field of environmental protection, such as automobile exhaust purification and industrial waste gas treatment, it can also be used as a catalyst to convert harmful gases into harmless substances.

Fuel cell catalyst: Fuel cell is an efficient and clean energy conversion device, Palladium Nickel alloy particles can be used as a catalyst in fuel cell to promote the electrochemical reaction between hydrogen and oxygen, and to improve the performance and efficiency of fuel cell.

Metal-ceramic welding: Palladium nickel alloy materials containing 2% – 9% titanium can be used to weld metal-ceramic to metal-ceramic and metal to metal-ceramic. These welding materials maintain good stability and weld strength at high temperatures, ensuring the quality and reliability of welded joints.

Hydrogen energy: Palladium nickel alloys have a certain adsorption capacity for hydrogen, and alloys containing more than 5% nickel are saturated with hydrogen to produce only the а phase. Therefore, it can be used in the process of hydrogen storage, separation and purification, providing technical support for the development and utilisation of hydrogen energy.

Electroplating: In the electroplating process, palladium nickel alloy particles can be used as a component of the electroplating solution to form a palladium nickel alloy coating on the surface of other metals by means of electroplating. This kind of plating layer has good abrasion resistance, corrosion resistance and decorative properties, and can be used to improve the surface performance and service life of metal products.
