Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, presents our Cold Drawn Steel Irregular Spring with a 2.5mm wire diameter and a 100N/mm spring rate. Designed for heavy-duty applications, this spring delivers exceptional durability and consistent performance under demanding conditions. Our factory leverages over two decades of expertise in wire and spring manufacturing, ensuring each piece meets rigorous quality standards for industrial clients worldwide.

This irregular spring is precision-engineered from cold drawn steel, offering superior tensile strength and fatigue resistance. The 2.5mm wire diameter provides a perfect balance between flexibility and load-bearing capacity, while the 100N/mm spring rate ensures reliable force output in compression or extension setups. Whether used in automotive suspensions, agricultural machinery, or heavy industrial equipment, this spring is built to withstand extreme stresses and repetitive cycles.

Key Features & Technical Specifications

Material: Cold drawn steel – high tensile strength, excellent wear resistance, and uniform grain structure.
Wire Diameter: 2.5mm (±0.05mm tolerance) – optimized for heavy load applications without compromising flexibility.
Spring Rate: 100 N/mm – precise force-deflection ratio, ideal for consistent performance in dynamic systems.
Shape: Irregular (custom geometry available) – tailored to fit specific mechanical assemblies or space constraints.
Surface Treatment: Options include plain, oiled, painted, or zinc-plated for enhanced corrosion resistance.
Heat Treatment: Stress-relieved and quenched/tempered upon request to meet specific hardness requirements.
Quality Control: 100% dimensional inspection and load testing per batch.

Parameter	Value
Wire Diameter	2.5 mm
Spring Rate	100 N/mm
Material Grade	Cold drawn steel (e.g., 65Mn, 60Si2Mn, or equivalent)
Max Deflection	Up to 50% of free length (depending on design)
Operating Temperature	-40°C to 120°C (standard); higher range available

Advantages & Customer Benefits

Enhanced Durability: Cold drawn steel reduces internal stress, extending service life even under cyclic loading.
Customizable Geometry: Irregular shapes can be designed to fit unique mounting requirements, reducing assembly complexity.
Consistent Force Output: The tight spring rate tolerance ensures predictable performance, critical for safety components.
Cost-Effective: Direct manufacturer pricing eliminates middlemen, offering competitive rates for bulk orders.
Low Maintenance: Optional surface treatments minimize rust and wear, reducing replacement frequency.
Versatile Applications: Suitable for presses, valves, actuators, and heavy machinery where high force and reliability are needed.

Frequently Asked Questions

Q: What is the maximum load capacity of this spring?
A: The load capacity depends on the spring's free length and design. With a 100N/mm spring rate, each millimeter of compression provides 100 N of force. We can calculate the maximum safe load based on your specific deflection requirements.
Q: Can you produce this spring in different wire diameters?
A: Yes, we offer customization for wire diameters from 0.5mm to 12mm. The 2.5mm diameter is a standard option, but we can adjust based on your load and space constraints.
Q: What surface treatments are available for corrosion protection?
A: We offer plain (as-drawn), oiled, painted, zinc-plated, and even powder coating. For harsh environments, zinc-plating is recommended for enhanced corrosion resistance.
Q: How do you ensure the irregular shape meets my specifications?
A: We use CNC coiling machines with programmable indexers to form complex shapes. We can work from your CAD drawing or a physical sample. Dimensional tolerances are typically ±0.1mm on outer diameters and ±1° on angles.
Q: What is the lead time for a custom order?
A: For standard designs, production takes 7–15 days. Custom shapes may require 15–25 days, including tooling setup. Rush orders are available upon request.
Q: Do you provide samples for testing?
A: Yes, we can provide samples at cost. For established clients, free samples are available for evaluation. Please contact our sales team to discuss your requirements.
Q: What is your minimum order quantity (MOQ)?
A: For standard springs, MOQ is 500 pieces. For custom dimensions, it may be 1000 pieces. Lower MOQ can be negotiated for trial orders.
Q: Can this spring be used in high-temperature environments?
A: Standard cold drawn steel performs well up to 120°C. For higher temperatures (up to 250°C), we recommend using alloy steel or stainless steel. Please inquire for heat-resistant alternatives.
