Palladium Alloy

  • Palladium

    Melting point 1554°C, boiling point 2970°C, density 11.99g/cm3, face-centered cubic structure, silver white appearance.

    Palladium is a transition element between nickel group and light platinum group. It is soft, with good ductility and plasticity. Palladium can be forged,rolled and drawn.

  • Palladium Properties

    Palladium soluble in aqua regia, hot nitric acid, sulfuric acid, slightly soluble in hydrochloric acid, insoluble in water. Dust may pose fire and explosion hazards.

    Palladium has very high hydrogen absorption, which makes it widely used in catalytic hydrogenation, dehydrogenation and petroleum cracking.

    Palladium is also carbon absorbent and can be used in the manufacture of CO monitoring devices.

    In dentistry and medicine, palladium alloys are used to replace damaged bones and joints.

    In industry, it is often used for thick film paste, internal and external electrode materials of multilayer ceramic capacitors, printed circuits, precision alloys, electrical instruments, etc.

  • Application of Palladium

    Palladium is an indispensable key material in high-tech fields such as aerospace, aviation, navigation, weapons and nuclear energy, as well as automotive manufacturing.

    Palladium is used primarily as a catalyst in chemistry.

    Palladium is fused with ruthenium, iridium, silver, gold, copper and other alloys, can improve the resistivity, hardness and strength of palladium, used in the manufacture of precision resistance, jewelry, etc.

  • Palladium Alloy

    Palladium alloy is an alloy composed of one or more elements, which is an important precious metal material. Most palladium alloys have good corrosion resistance, chemical stability and thermal stability, high melting point, low density and low price, and play an important role in many fields such as electrical contact, resistance, hydrogen purification, filler metal and jewelry materials.

  • Properties of Palladium Alloy

    Palladium alloy has excellent physical and chemical properties. First, palladium alloy has good corrosion resistance, can resist acid, alkali, oxidant and other chemicals attack. Secondly, palladium alloy has good electrical and thermal conductivity, which can effectively transfer electricity and heat energy. In addition, palladium alloy also has good machining properties, can be formed by cold processing, hot processing and other ways.

  • Characteristics of Palladium Alloy

    (1) Good machinability. Most palladium alloys can be made into tube, rod, wire, sheet and foil with complete specifications by cold processing or hot processing.

    (2) reliable and stable electrical contact performance, can be used to break contact, sliding contact, slip ring, brush and many other contact materials.

    (3) High resistivity (medium or high resistance), low and stable resistance temperature coefficient, suitable for winding, strain, temperature measurement and electric heating resistance materials.

    (4) temperature difference absolute thermoelectric potential is large, can be used as thermocouple materials.

    (5) High hydrogen penetration rate: the hydrogen penetration rate of palladium base binary or multiple alloy containing appropriate amount of silver, gold, boron, copper, nickel, platinum or rhodium is higher than that of pure palladium, and has quite high hydrogen absorption performance, can be used as hydrogen purification and detection materials.

    (6) palladium, palladium-iridium, palladium-iridium and palladium-ruthenium alloys with high melting point and strong corrosion resistance can be used as chemical utensils or artificial fiber spinneret materials.

    (7) melting, flow point and wetting, good dispersion, such as PdNb50, PdNi40 and PDCUNI50-15 alloy suitable for high temperature solder.

    (8) Light weight, beautiful color, corrosion resistance and anti-tarnishing ability is strong, suitable for lighter pins and earrings and other accessories.

  • Classification of Palladium Alloy

    (1) palladium gold alloy Pd-Au alloy, containing more than 20% gold Au alloy insoluble in nitric acid, due to the high melting point and corrosion resistance of this kind of alloy, it is used to manufacture chemical vessels; Alloys containing 20%Pd-30%Au are used to make artificial fiber drawing dies.

    (2) Pd-Ag alloy, the corrosion resistance of the alloy containing less than 50% silver Ag is close to palladium, the addition of gold and platinum can improve the performance of the alloy, Pd-Ag alloy containing 50%Ag and 10%Pt or Au can be used to manufacture corrosion resistant parts and watch cases of optical instruments

    (3) Palladium-iridium alloy PD-IR alloy, Iridium Ir can significantly improve the corrosion resistance of Pd, and Pd-IR alloy is used as an electrical contact point.

    (4)Other palladium alloy: the maingrades are PdAgCuAuPtZn, PdCu, PdNi, etc., can be used as brush materials, high temperature solder.

  • Application of Palladium Alloy

    Palladium alloy is widely used in automobile, electronics, chemical industry and other fields. First, in the automotive sector, palladium alloys are mainly used in the manufacture of catalytic converters, oxygen sensors and other components. Secondly, in the field of electronics, palladium alloy is mainly used in the manufacture of capacitors, resistors, connectors and other components. Finally, in the field of chemical industry, palladium alloy is mainly used in catalyst, catalyst support and other aspects.

    Palladium alloy is an important metal material with excellent physical and chemical properties, widely used in automotive, electronic, chemical and other fields. In the future, with the continuous development of science and technology, the application of palladium alloy will be more extensive, and its application in environmental protection, new energy and other fields will be further expanded.
