Products Description
High Temperature Resistant Metal Bellows are an essential component in solid oxide fuel cells. They play a significant role in the cell's efficiency and overall performance. These bellows are typically made of nickel, which is a highly conductive metal that can withstand high temperatures. In a solid oxide fuel cell, the metal bellows are used to provide a sealed, flexible connection between the fuel cell's stack and its peripheral components, such as manifolds and hydrogen delivery systems. The bellows also allow for thermal expansion and contraction of the stack, which helps to prevent damage from occurring due to temperature changes. Overall, metal bellows serve as a critical component in the solid oxide fuel cell, helping to optimize its performance and efficiency.

Inconel 625 is a precipitation strengthened nickel-based high-temperature alloy, mainly reinforced with molybdenum and niobium. It exhibits excellent corrosion and oxidation resistance, and maintains good tensile and fatigue properties from low temperatures up to 980℃. Additionally, it is highly resistant to stress corrosion in saline environments. As a result, Inconel 625 can be widely utilized in the manufacturing of airplane engine components, aerospace structural parts, and professional chemical equipment.
Advantages of processing technology
Our metal bellows first uses metal foil to make welded pipes, and then makes molds after calculation. The forming method is to inject liquid into the inside of the welded pipe, and limit the shape through the mold. After two presses, the final shape is formed. The molding pressure of our products is generally greater than the working pressure of metal bellows, so our products are exempt from inspection after they are manufactured.
Our company has a variety of molds, and has the production capacity of different metal materials, and can control the quality of products from raw materials to finished products.
