Metal bellows are designed in a way that they compress or expand on the application of pressure, and come back to their original share once the pressure is removed.
As they are most commonly used as a part of piping applications, their convolution geometry and thickness is designed according to the temperature and pressure range as well as pipe capacity.
In cases where pipes expand due to increase in temperatures, metal bellows act as a resistance by limiting the compression by force.Metal bellows are commonly used in various industries such as manufacturing, water treatment, mining, automotive, power generation, and wind energy generation.

Though the global metal bellows market is characterised with stringent governmental regulations, end user preference for metal bellows over its other alternatives is expected to boost the profitability of manufacturers across various regions.
Demand for Metal Bellows in Aerospace & Defense Industry to Grow Strong
The adoption of metal bellows in a wide range of end-use industries such as automotive, semiconductor, oil & gas, and pharmaceuticals is significantly high, which is mainly driving the metal bellows market.
However, the demand is relatively higher in the aerospace & defense industry, and this is mainly influencing the growth prospects of the global metal bellows market.
In the past two years, the aerospace & defense industry witnessed a major downfall in the commercial aircraft manufacturing and deliveries, which is mainly attributed to the worldwide outbreak of the novel coronavirus. However, the demand for metal bellows in the industry remained fundamentally strong as leading players in the aerospace industry.
Global leaders such as Airbus and Boeing, are known to be holding a significantly large backlog of orders, and this is currently holding up the production activities for these players.
In addition, the industry is witnessing a growing number of new original equipment manufacturers (OEMs) entering the landscape, along with the rising development of fuel-efficient alternatives for conventional elements of commercial aerospace products.
This indicates that the adoption of metal bellows in the global aerospace & defense industry will further bolster the growth of the global metal bellows market in the coming years.

High Performance Parameter of Metal Bellows over Non-metallic Bellows Trigger Demand
While metal bellows find applications in a wide range of end uses and applications, the use of non-metallic bellows is also significantly high. Non-metallic bellows are a type of flexible connectors manufactured using synthetic or natural fibers.
These are commonly used in applications that are primarily developed to offer stress relief in various industrial end uses – mainly in the piping industry. They are also used in applications involved in mechanical vibrations and thermal movements.
Though both – metal and non-metal bellows are used in distinct applications, based on their performance characteristics, the prior shows advanced parameters that make them suitable for a wider range of applications than the latter.
Metal bellows are higher in demand than non-metal bellows mainly due to their higher pressure range, temperature range, flexibility in connection types, along with its suitability with various fluids and gases.
With the rugged, multiple layer designs, metal bellows are designed for applications performed in a wide range of temperature range from -420°F to +1800°F. Whereas, non-metal bellows usually suit applications under the temperatures around 230°F, based on the materialist properties of synthetic materials used.
Consequently, though both the types of bellows are used in different applications based on their utilities and importance, metal bellows are more commonly used in multiple industrial applications.
Metal Bellows Market: Region-wise Analysis
Based on the geographical factors, the metal bellows market is broadly segmented into seven regions – North America, Latin America, Europe, East Asia, South Asia, Oceania, and Middle East & Africa.
According to different geographies and specific geopolitical factors, the market for metal bellows is expected to witness incremental growth in the Asia Pacific region.
The region plays an important role in the supply chain operations as most manufacturers have their production centers in developing Asian countries such as China and South Korea. In addition, increasing presence of raw material suppliers, retailers, and metal bellow manufacturers in the region further amplifies the growth potential of the Asia Pacific metal bellows market.
On the other hand, developed regions including North America and Europe, are also expected to create sizable demand for metal bellows with the increasing growth of the market. Developed countries such as the United States along with some countries in Western Europe – Germany, France, and Spain, are expected to contribute to the increasing growth of the global metal bellows market.
Due to the coronavirus outbreak, the metal bellows market in most Asian countries witnessed sluggish growth. However, countries such as China and South Korea are recovering fast from the pandemic, which is expected to revive the metal bellows market in these regions.
In the coming years, the growth prospects of the metal bellows market in Asia Pacific region are expected to improve in the coming years.
