Dimension
1. Material: high carbon spring steel; music wire; stainless steel(SUS301,302,304,316,201,202);alloy steel(60Si2MnA,55CrSi,50CrV,60SiCr8A);copper wire ,iron wire ,
2. Wire Diameter: 0.1-65.0mm
3. Surface treatment: become black, Zinc/ Nickel/Silver/Golden/Tin plated ,polishing ,anti-rust oil, passivation ,powder coating, shot blasting
4. Certification: ISO9001:2000, ROHS
5. Packing :Inner plastic bags and outer cartons ,shipping with plastic pallet
6. Can made by your drawings, sample and dimension
Formula:
1) OD=ID+d (OD: outside diameter; ID=inside diameter; Dm=mean diameter; d=wire diameter)
2) F=Gd4*f/8Dm3Nact (F= load; G=gravity; f=deflection; Nact=active number of coil)
3) F'=F/f (F'=Spring rate)
