Cold Drawn Coils
Cold drawn coils are produced according to EN 12166 European Standard. They are coil shaped high precision products suitable for efficient chip removal in free machining process.
They increase production speed and productivity by reducing the loading times of machines

The necessary mechanical properties if different than M,
E.g. Hardness value min. H115 for 115 HBW
- Cross-sectional Shape
- E.g. RND for round, SQR for square, HEX for hexagonal, OCT for octagonal, RCT for rectangular (bar), PFL for profile
- Nominal Cross-sectional Dimension
- E.g. For width x thickness (6.0 x 5.0)
- Tolerances
- Class A,B,C,D or E
- Corner Type
- When necessary, E.g. SH - Sharp or RD - Rounded
Material description CuZn40Pb2 or CW617N, material status H115, rectangular section, nominal measures of 6,0 mm x 5,0 mm class B tolerance, sharp corner; complying with the restrictions on the 4MS and UBA list for drinking water applications and with EN 12166 standard. Cold drawing coils with the properties above should be shown as follows.
The product designation provides a standardized pattern of designation of the main order information when combined with quantity, length / piece and weight tolerances. Additional order information may include; the test method, the type of packaging information and quality assurance certification.
