Spring Wire & Alloy Spring Wire
Spring Wire
Application: for general application spring and mechanical spring.
Beside to make the wire according to the standard, we also try to supply the wire according customer’s
special requirement.
Technical specification:
(1)Standard: DIN17223-1-1984,EN10270-1,ASTM-A227,GB4357-89
(2)Size: 0.20mm-14.0mm
(3)multi-purpose in
1. General introduction:
Raw material is rigorously selected and approved before put into processing while five main
chemical compostion results shown as below:

C Si Mn P S
0.40-1.00 Max 0.35 0.30-1.50 Max 0.04 Max 0.04

For serving spring and wire form industry, high tensile strength is not the ultimate goal to pursue, 

but the balance of flexibility and tensile strength to prevent our wire from deformed or broken up 

during winding in spring machine. In addition, for other usage, our products also have gained a

sound reputation from the appliance as controlling cable or connecting wire for automobile industry

and hard needle. Hot-dipped and electro-galvanized spring wire available.

2. Range of application:

(1) mattress spring

(2) compression spring

(3) extension spring

(4) torsion spring

(5) mechanical spring

(6) wire forms

(7) core of controlling cable

(8) connecting wire

(9) hard needle

3. Specifications:

(1) 0.30mm-13.00mm to comply with DIN17223-1-1984 Class B

(2) 0.30mm-3.50mm to comply with DIN1723-1-1984, Class C, EN10270-SH
