6201 Rod
AlMg0.6Si0.9 — High-Strength Conductor Wire Rod
Overview
Higher Mg and Si content than 6101 delivers greater tensile strength (300 MPa T81) at 52% IACS — used where long-span overhead lines demand superior mechanical performance
Stress corrosion sensitivity in T8 temper — follow recommended storage and installation guidelines

Properties
Manufacturing Process
Step 1
Billet Preparation
6201 billets preheated to 490–520 °C; higher Si and Mg content requires careful temperature control to fully dissolve Mg₂Si phase.
Step 2
Continuous Casting & Rolling (CCR)
Molten metal cast and hot-rolled in-line via the Properzi/CCR process; rapid solidification achieves fine grain and retained solid solution.
Step 3
Hot Rolling
Multi-stand rolling reduces diameter to 6–12 mm at 400–460 °C; reduction schedule balances grain refinement and surface quality.
Step 4
Quench & Temper
Immediate water quench after final pass achieves T1 temper; solution treatment ensures maximum precipitation hardening response.
Step 5
Artificial Aging (T81)
Two-step aging cycle achieves T81 temper with peak tensile strength (300 MPa) and 52% IACS conductivity.
Step 6
Inspection & Dispatch
Tensile, elongation, and conductivity measured per coil to IEC 60889 / ASTM B399. Full traceability certificates issued.
