Materials for Canted Coil Springs: BeCu vs Stainless Steel Comparison Guide
Explore the best materials for canted coil springs. Compare beryllium copper vs stainless steel in strength, conductivity, corrosion resistance, and applications. A complete material selection guide by HANDA.
Material selection is one of the most critical decisions in the design of コイルスプリング. Because these springs are used in precision applications such as EMI shielding, electrical contacts, sealing, and latching, the chosen material directly affects spring force stability, fatigue life, conductivity, and environmental resistance.
で HANDA, we primarily manufacture canted coil springs using ベリリウム銅（BeCu） そして ステンレス鋼 alloys. Each material offers distinct advantages depending on mechanical and electrical requirements. This pillar page explains how to choose the right material and provides a detailed comparison between BeCu and stainless steel canted coil springs.
Common Materials Used in Canted Coil Springs
1. Beryllium Copper (BeCu)
Beryllium copper is a high-performance copper alloy widely used in electrical and EMI shielding canted coil springs.
Key properties:
- 優れた導電性
- High elastic limit and fatigue resistance
- Non-magnetic
- Low contact resistance
BeCu canted coil springs are ideal for applications requiring both stable mechanical force and reliable electrical performance.
2. Stainless Steel
Stainless steel remains one of the most versatile materials for コイルスプリング, offering a wide range of grades to meet different needs.
Common grades used by HANDA:
- 301 / 302 – high strength, cost-effective
- 304 – good corrosion resistance
- 316 – excellent resistance to chemicals and salt spray
- 17-7PH – high fatigue strength and elastic stability
Stainless steel canted coil springs are preferred when mechanical durability and corrosion resistance are the primary concerns.
BeCu vs Stainless Steel: Canted Coil Springs Comparison
Mechanical Performance
Beryllium copper provides excellent fatigue resistance and maintains consistent spring force under repeated compression cycles. Stainless steel, especially 17-7PH, offers higher load capacity and is better suited for high-force applications.
Electrical Performance
BeCu significantly outperforms stainless steel in electrical conductivity. For EMI shielding, grounding, and electrical contact canted coil springs, BeCu ensures low resistance and stable signal transmission.
耐環境性
Stainless steel grades such as 316 provide superior corrosion resistance in harsh environments. BeCu performs well in most conditions but may require plating in extreme chemical exposure.
