| Materials | |||
| Your choices are... | |||
| Aluminum | Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. | ||
| Beryllium Copper | Beryllium copper is an alloy of beryllium and copper. | ||
| Brass | Brass is an alloy made of copper, iron, lead and zinc. | ||
| Copper | Copper is a soft, malleable metal that has high electrical and thermal conductivity. | ||
| Hastelloy® | Hastelloy® alloys provide high resistance to uniform attack and localized corrosion resistance. They also provide stress corrosion, cracking resistance, and ease of welding and fabrication. Hastelloy is a registered trademark of Haynes International, Inc. | ||
| Inconel® | Inconel® is an alloy of nickel, carbon, chrome, iron, molybdenum and titanium. It has good temperature and oxidation resistance characteristics. Inconel is a registered trademark of Special Metals Corporation. | ||
| Monel® | Monel® alloys have high strength and resistance to a range of corrosive media, including seawater, hydrofluoric and sulfuric acids, and alkalis. Monel is a registered trademark of Special Metals Corporation. | ||
| Nickel | Nickel is a shiny, relatively soft metal that has excellent corrosion-resistance properties. | ||
| Phosphor Bronze | Phosphor bronze is a copper-based alloy with a small percentage of tin for hardness. | ||
| Stainless Steel | Stainless steel is a chrome nickel-based steel alloy that is corrosion resistant. | ||
| Steel | Bellows are made of standard steel alloys. | ||
| Tantalum | Tantalum is a durable, corrosion-resistant metal. | ||
| Titanium | Titanium is ductile, lightweight, strong, and corrosion resistant. | ||
| Other | Other unlisted, specialized, or proprietary materials. | ||

| Bellows Construction | |||
| Your choices are... | |||
| Electroformed | Electroformed bellows are made by depositing layers of metal, usually based on nickel, onto a mandrel of aluminum. When the desired thickness is achieved, the mandrel is melted away and the bellows is left behind. | ||
| Chemically Deposited | Chemical deposition is a method of forming bellows by electro-depositing metal on a mandrel. | ||
| Mechanically Formed | Mechanically formed bellows include both roll-formed and hydroformed types. | ||
| Welded | Welded bellows are a series of convoluted rings or washers, which are stacked on top of each other and welded on the inside and outside circumference. | ||
| Other | Other unlisted, specialized, or proprietary bellows construction. | ||

Applications
Back to Top
|
|
| ||
| Your choices are... | |||
| Aerospace | Metal bellows are used in aerospace applications for protecting moving parts on critical components. | ||
| Automotive | Bellows are suitable for automotive applications. | ||
| Chemical | Bellows are used in chemical plants, where moving parts on machinery need protection from corrosive elements. | ||
| Electrical Contacts | Bellows can be fitted to moving contacts in distribution equipment, usually gas or vacuum-filled interrupters. | ||
| Expansion Joint | Expansion joints connect two fixed assemblies or pipes and provide allowance for movement due to service load, shock, or thermal cycles. | ||
| Fluid Coupling | Couplings can be static or rotating. In fluid applications, bellows allow leak-proof transfers. | ||
| High Purity | Bellows are used in high-purity environments. | ||
| HVAC | Bellows are suitable for applications involving the environmental extremes encountered in heating, ventilating, and air conditioning (HVAC) systems. | ||
| Marine | Bellows are used to protect moving parts from corrosive elements such as salt water and salty air. | ||
| Motion Coupling | Couplings can be static or rotating. Rotating couplings offer good torque ratings, zero backlash, and a low moment of inertia. | ||
| Petrochemical | Bellows isolate volatile petrochemicals from anything that may strike and ignite rotating equipment. | ||
| Semiconductor | Bellows are suitable for applications that involve the manufacture of semiconductors and require very clean operating conditions. | ||
| Other | Other unlisted, specialized, or proprietary applications. | ||
