Brass/tin Bronze/stainless Steel Elastic Bellows
| Bellows are widely used in various industries for their flexibility, durability, and ability to withstand different environmental conditions. Among the most common materials are Brass Bellows, Tin-Bronze Bellows, and Stainless Steel Bellows. Each has unique properties, manufacturing techniques, and applications. | |||||||||
The selection of bellows depends on the specific requirements of the application. Brass bellows excel in cost-effectiveness and appearance, Tin-bronze bellows perform well in moderately corrosive environments, and Stainless steel bellows are unmatched in durability and high-stress applications.
Manufacturing Differences
| Aspect | Brass Bellows | Tin-Bronze Bellows | Stainless Steel Bellows |
|---|---|---|---|
| Material Composition | Copper-zinc alloy (e.g., 60/40 ratio) | Copper-tin alloy (e.g., 88/12 ratio) | Austenitic steel (e.g., SS304, SS316) |
| Manufacturing Method | Deep drawing, welding, or hydroforming | Precision stamping or brazing | Hydraulic forming or laser welding |
| Flexibility | Moderate | High | Excellent |
| Corrosion Resistance | Good in non-aggressive environments | Better in slightly acidic environments | Excellent in harsh conditions |
Technical Specifications
| Parameter | Brass Bellows | Tin-Bronze Bellows | Stainless Steel Bellows |
|---|---|---|---|
| Operating Temperature | -40°C to 200°C | -40°C to 250°C | -200°C to 600°C |
| Pressure Resistance | Low to medium | Medium | High |
| Lifespan (cycles) | 1M - 1.5M | 1.5M - 2M | Over 3M |
| Weight | Lightweight | Moderate | Heavier than alloys |
Applications
| Bellows Type | Applications |
|---|---|
| Brass Bellows | HVAC systems, plumbing, and decorative applications |
| Tin-Bronze Bellows | Marine engineering, electrical components, and moderately corrosive environments |
| Stainless Steel Bellows | Aerospace, automotive exhaust systems, and high-pressure pipelines |
