Differences in Material and Processing Costs

• Stainless steel ( commonly grades 304 & 316 ) contains precious metals such as chromium and nickel, resulting in inherently high raw material costs. In addition, its high hardness and toughness necessitate precision CNC machining to meet the stringent accuracy requirements of RF connectors, leading to substantial energy consumption and processing costs.

• Copper alloys such as brass and phosphor bronze feature lower raw material prices and relatively soft textures. They can be easily formed via simple processes like stamping and cutting, with minimal material waste and high production efficiency, which significantly reduces overall manufacturing costs.

• Stainless steel SMA connectors are primarily designed for extreme environment compatibility. For instance, their excellent salt spray and acid-alkali resistance make them ideal for marine equipment, while their high mechanical strength suits the vibration and shock conditions of aerospace applications. These high-end scenarios impose rigorous requirements on material purity, surface treatment and performance testing (e.g., 480-hour salt spray testing), which further elevates product pricing.
