Pure Copper Round Plate And Heavy Duty Circle Washer For Cnc Machining And Fabrication Hella Conductive Straight Up Premium For Metal Processing And Welding Projects One Point Two Millimeter Thick By Three Hundred Millimeter Wide

Pure copper flat stock for CNC milling and light welding prep work
✔️ 300 mm diameter pure copper washer measuring 1.2 mm thick panel

This single unit is a dense metal disc engineered for precision shaping and heavy load distribution. You will typically mount it inside automotive service bays, custom hydraulic manifolds, and electrical grounding stations where stable current paths directly impact safety and performance. Mechanics rely on this straightforward geometry because it handles torque spikes without warping.

✅ High conductivity alloy maintains steady thermal flow during rapid heat cycling
✅ Soft yet durable matrix accepts quick drilling and clean solder joints
✅ Tolerant surface geometry fits securely onto standard bench mounting plates

💡 How do you safely clean and store high conductivity copper discs for workshop longevity?

These handy flat blanks stay reliable when you handle them right during routine maintenance.

* Run a stiff nylon brush over mill marks to remove oil residue before stacking

* Spray a thin layer of anti corrosion gel on exposed edges to lock out humidity

* Toss leftover units into zip bags whenever tool benches sit idle between heavy jobs
