T2 Copper Material Introduction Used In CNC projects

Basic Introduction

T2, short for red copper used In CNC projects. T2 copper refers to a copper-silver alloy, in which the copper + silver content of copper is >99.9%, and there is no requirement for phosphorus. The conductivity is ≥56Ms/m, and the resistance is ≤0.0178x10-6 Ω.m.
