Product Introduction
| Spring Coil Technical Specifications | |
| Specification | Details |
| Common Material Types | High-Carbon Spring Steel (e.g., SAE 1060-1095): General-purpose, cost-effective for static and low-cycle dynamic loads. Alloy Spring Steel (e.g., SAE 5160, 6150): Chromium/vanadium alloyed for higher fatigue strength, toughness, and temperature resistance. Stainless Steel Spring Wire (e.g., ASTM A313 302/316): For corrosion resistance and non-magnetic properties. Copper Alloys (e.g., Phosphor Bronze C51000, Beryllium Copper C17200): For electrical conductivity, corrosion resistance, and non-sparking requirements. Nickel Alloys (e.g., Inconel X-750, Monel): For high-temperature and highly corrosive environments. |
| Available Tempers & Conditions | Hard Drawn (HD): Cold drawn to high tensile strength, general-purpose. Oil Tempered (OT): Quenched and tempered for higher strength and toughness than hard drawn. Annealed (Soft): For severe coiling or forming before final heat treatment. Solution Annealed (for Precipitation-Hardening alloys): Ready for final aging treatment. Prestressed/Preset: Pre-deflected to reduce set in service |
| Wire Diameter Range | Fine Wire: 0.10 mm (0.004") to 1.00 mm (0.040") Standard Range: 1.00 mm (0.040") to 10.00 mm (0.394") Heavy Gauge: 10.00 mm (0.394") to 20.00 mm (0.787") |
| Coil Parameters | Inner Diameter (ID): Defined by mandrel size during coiling, typically from 5 mm to 500 mm+. Outer Diameter (OD): OD = ID + (2 x Wire Diameter). Pitch: Distance between adjacent coils; can be constant (compression) or variable (extension). Total Coils & Active Coils: Total number of coils vs. coils contributing to spring action. |
| Coil Geometry Types | Compression Springs: Open or closed ends, constant pitch, designed to resist compressive forces. Extension Springs: Initial tension, hooks/loops on ends, designed to resist stretching forces. Torsion Springs: Ends configured to apply torque, coils may be close-wound or have pitch. Conical/Volute Springs: Progressive rate, often for vibration damping or space constraints. |
| Key Mechanical Properties | Tensile Strength: Varies greatly with material and temper (e.g., HDMB Spring Steel: 1720-2070 MPa). Modulus of Elasticity (Shear Modulus, G): ~79 GPa for steel, ~45 GPa for phosphor bronze. Spring Rate (k): Force per unit deflection (N/mm or lb/in), calculated from wire diameter, coil diameter, and active coils. Fatigue Life: Critical for dynamic applications; influenced by material, surface finish, and stress levels. |
| Standard Specifications | ASTM A227/A228 (Hard-Drawn & Music Wire): Cold-drawn carbon steel spring wire. ASTM A229 (Oil-Tempered Spring Wire): Oil-tempered carbon steel wire. ASTM A313 (Stainless Steel Spring Wire): Austenitic stainless steel spring wire. SAE J113 (Spring Wire): Automotive spring wire specifications. EN 10270 (Steel Wire for Mechanical Springs). |
| Surface Finish & Treatment | Plain (As-Drawn/Oil-Tempered): Standard finish. Galvanized/Zinc Coated: For corrosion protection. Shot Peened: Improves fatigue life by inducing compressive surface stresses. Coated (PVC, Nylon, Teflon): For insulation, noise reduction, or chemical resistance. Ground Ends (Compression Springs): For parallel and stable seating. |
| Design & Performance Parameters | Spring Index (C): Ratio of Mean Coil Diameter to Wire Diameter (typically 4-12). Solid Height: Length when coils are fully compressed; critical for installation space. Initial Tension (Extension Springs): Built-in force holding coils together. Stress Relaxation/Creep: Loss of load over time, especially critical at elevated temperatures. |
| Primary Applications | Automotive & Transportation: Valve springs, suspension springs, clutch springs, seat mechanisms. Industrial Machinery: Actuators, vibration isolators, return mechanisms, precision instruments. Consumer Products: Pens, toys, mattresses, locks, appliances, power tools. Aerospace & Defense: Landing gear, control systems, ordinance, shock absorbers. Medical Devices: Surgical tools, drug delivery systems, prosthetic components. |
