HooTai Spring offers differet type of spring materials for your choice
At Hootai, we understand that the material of a spring plays a crucial role in its performance, durability, and resistance to environmental conditions. That’s why we offer a wide selection of high-quality spring materials to meet the demands of various applications, from industrial to medical and consumer use.
Usually we use the following types of materials：
Usually, we use the following types of materials：
- Stainless steel wire（SUS）
- Carbon steel wire (SWC)
- Gin wire （SWP）
- Copper wire
- Iron wire
Details for different type of spring material
We often use stainless steel materials to make springs in highly acidic and humid environments.
| Material | Type | Model |
| Stainless steel wire（SUS） | Magnetic, non-magnetic, glossy and matte (resin surface, dark surface) | 201、202..； |
| 301、302、303、304、305、309、310、316、321..； | ||
| 403、410、420、430 630、631..； |
Medium-carbon steel and high-carbon steel can be used for springs, but because of its low hardenability and strength, can only be used to create a smaller cross-section, less force springs.
| Material | Type | Model |
| Carbon steel wire (SWC) | Low carbon steel wire, high carbon steel, manganese steel wire, nickel wire, galvanized iron wire | 60SizMNA、60SizCRVA |
Music wire also know as paino wire, its mechanical properties are good tensile strength and bremsstrahlung, and it is an excellent tensile spring material.
| Material | Model | Feature |
| Gin wire （SWP） | SWP-B；SWP-A | Anti-tension, long service life |
Copper Alloys have good corrosion resistance and electrical conductivity which are widely use in electronics, electrical appliances, antennas, etc.
| Material | Type | Feature | |
| Copper wire | Phosphorus copper wire, tinned copper wire, nickel-plated copper wire, bronze, copper, phosphorus, copper, beryllium copper, etc. | Good electrical conductivity Electronic appliances, antennas, etc. | |
Brass springs provide good electrical conductivity and excellent corrosion resistance, especially in marine and electrical applications. While not as strong as steel, brass is non-magnetic and has a pleasing appearance, often used in decorative and sensitive electrical components.
Inconel springs are high-performance springs designed for extreme environments. Inconel alloys, such as Inconel X-750 or 718, offer outstanding heat and corrosion resistance. These springs perform reliably in high-temperature and high-stress applications such as gas turbines, oil & gas, and nuclear systems.
Titanium springs are lightweight, highly corrosion-resistant, and have a high strength-to-weight ratio. These springs are ideal for aerospace, medical implants, and marine industries where every gram matters and durability is critical.
Carbon steel springs offer high strength and are often used in dry environments. Oil-tempered and hard-drawn carbon steel are typical materials in this category. These springs are cost-effective and commonly found in heavy-duty mechanical assemblies.
