| Circlips - N1400
The standard material for all circlips with the exception of some smaller external types which are made from beryllium copper, is carbon spring steel. Other materials are available on request including stainless steel (DIN 1.4122), phosphor bronze and beryllium copper. It should be noted that parts made from special materials cannot be guaranteed to meet the thickness specifications of standard parts, due to the wider tolerance bands available on raw materials. The normal thicknesses are maintained but allowance should be made for additional thickness tolerances. Care should be taken when specifying special materials that no galvanic interaction between the circlip and groove material is likely to occur. This is usually only a problem when the assembly is in contact with conductive atmospheres. Plated and Other Finishes Phosophate and oil is the standard finish on most circlips, the remainder being self finish and oil. Where improved properties or appearance are required for operation in corrosive environments plating provides additional protection. Zinc plated finishes, with either clear or yellow chromate passivation, is available and may be electrolytic or mechanical at our discretion. Plated thickness can be 6 micron or 12 micron and will increase the overall thickness of the circlip. It is essential to select the finish required with a view to the operating conditions including groove material or finish, since some combinations may actually accelerate corrosion. Coloured lacquer finishes, for identification purposes, are available subject to enquiry are copper flashed. Download technical data sheet - PDF
