What is the Cold Draw Tubing Dimensional Tolerance?

The coiled brass/copper tube offered by Tech EDM Company is famous for its tight tolerance on outer diameter and wall thickness. For example, its standard tolerance is +/-0.01mm on O.D., and it is +/-0.015mm on wall thickness for the copper/brass tubes of diameters:0.3mm-3.0mm; (The special standard: +/-0.005mm can be met in our company too).

Attached please find the tolerance list for tubes with various diameters for your reference.

These cold draw tubes can be applied in the following fields: Industrial lines like, EDM electrode tubing, air space, fishing parts pen pipe, oil tube, water supplying tube, air condition making, building industrial, etc.
