Product introduction
in non-ferrous metals
A pure nickel gasket is a sealing element made of high-purity nickel (usually Ni200 or N6 material, with a purity of more than 99.5%) as the main raw material. It is formed by precision stamping, cutting, or machining. It has excellent physical and chemical properties and is widely used in industrial scenarios that require high sealing, corrosion resistance, high temperature, and high pressure. The surface of the pure nickel gasket has a silver-white metallic luster, a flat surface, and no oxide layer. The general thickness is between 0.5 mm and 5 mm. Different shapes, sizes, and thicknesses can be customized according to customer requirements.
Pure nickel is chemically stable at room temperature and can effectively resist erosion by a variety of corrosive media, especially in alkaline environments. During the production process, high-purity nickel plates are used and undergo strict annealing treatment to eliminate internal stress and ensure that the gasket is not easy to deform or crack during long-term use. At the same time, surface treatment such as silver plating or special cleaning can be performed to meet the needs of high-purity applications such as semiconductors and special gases.
Pure nickel gaskets have significant advantages in thermal and electrical conductivity. They have high thermal conductivity and can quickly transfer heat. They are suitable for sealing equipment that requires uniform temperature distribution. In terms of mechanical properties, it has both certain strength and good plasticity, making it easy to install and compress and seal. In vacuum or high-pressure environments, pure nickel gaskets can achieve extremely low leakage rates and meet strict environmental and safety standards.
The development of pure nickel gaskets stems from the demand for high-performance sealing materials in the chemical industry and the aerospace industry. With the advancement of industrial technology, its applications have expanded to new energy, pharmaceutical, and electronic industries. Choosing pure nickel gaskets can not only improve the reliability and life of equipment operation but also reduce maintenance costs. In the context of global energy transition and high-end manufacturing, pure nickel gaskets are becoming one of the key basic components.

Advantages of sanded surface
The greatest advantage of pure nickel gaskets is their excellent corrosion resistance. In strong alkaline environments, such as caustic alkali production and the chlor-alkali industry, it can operate stably for a long time, far better than stainless steel or carbon steel gaskets. It also has good resistance to neutral salt solutions, distilled water, and many organic solvents, reducing the risk of leakage caused by corrosion and extending the service life of the equipment.
Strong adaptability to high temperature and high pressure. Pure nickel maintains good mechanical properties at higher temperatures and is not prone to softening or creep, making it suitable for steam systems, heat exchangers, and high-temperature reactors. Good toughness at low temperature, with no low-temperature brittleness problem. It has excellent thermal and electrical conductivity and can effectively manage heat and static electricity. It is suitable for electronics, batteries, and precision instruments.
It has good plasticity and ductility and is easy to compress to form a tight seal during installation. The required preload force is low, reducing the risk of flange deformation. It has excellent resilience and can maintain the sealing effect after repeated disassembly and assembly. Compared with composite gaskets, pure metal structures are simpler, have strong blowout resistance, and are suitable for extreme pressure fluctuation environments.
The high purity characteristics make it suitable for use in semiconductor manufacturing, special gas transportation, pharmaceuticals, food processing, etc., without introducing impurities to contaminate the medium. Environmentally friendly, no harmful substances are released, and it complies with RoHS and other standards. It has high processing flexibility and can customize complex shapes to meet the needs of special-shaped flanges. The cost-performance ratio is excellent, and the price-performance ratio is outstanding under many harsh working conditions.
Product Application
Semiconductor and electronics industry
Special gas delivery systems, vacuum chambers, and VCR joint seals use their high purity and low gas outflow rate to avoid contamination of wafer manufacturing.
Aerospace and military industry
Seals used in missiles, aircraft hydraulic and fuel systems, and satellite propulsion devices require extremely high reliability and low leakage.
Electric power and energy field
It plays a key sealing role in steam systems and boiler connections of thermal power and nuclear power, as well as new energy hydrogen energy equipment (such as electrolyzers and hydrogen storage systems). Its hydrogen embrittlement resistance and conductive properties are particularly suitable for the hydrogen energy industry chain.
chemical industry
In chlor-alkali and caustic soda production equipment, it is used for sealing pipes, flanges, valves and pumps to effectively resist strong alkali corrosion and ensure production continuity. In the petrochemical industry, it is used for sealing high-temperature and high-pressure pipelines in catalytic cracking and hydrogenation units.

FAQ
Pure nickel gaskets and nickel alloy gaskets are essentially different in material composition. The nickel content of pure nickel gaskets can be as high as 99.0% or more, mainly utilizing the inherent characteristics of nickel metal itself, while nickel alloy gaskets are alloys formed by adding nickel as the base and adding other metal elements (such as chromium, molybdenum, copper, etc.), such as Inconel, Monel, and Hastelloy. Therefore, pure nickel gaskets perform particularly well in high-temperature and strong-alkali environments, but in sulfur-containing or strongly oxidizing-acid environments, nickel-alloy gaskets may have better corrosion resistance.
