General Recommendations for Spring Components

Material Selection

Spring Steel: Best suited for projects requiring high strength and elasticity at a cost-effective price point. Recommended for industrial and automotive applications where corrosion risks are minimal or controlled through surface treatment.
SUS301H Stainless Steel: Ideal for applications requiring a combination of high strength, corrosion resistance, and formability, such as automotive spring clips and structural components.
Phosphor Bronze (C5191): Perfect for precision applications where fatigue resistance, wear resistance, and moderate conductivity are essential, particularly in electronic connectors and terminals.
Beryllium Copper: Recommended for high-performance needs in aerospace and telecommunications, where superior elasticity, fatigue resistance, and conductivity are critical.
