Our Custom Non-Standard Tungsten Copper Alloy Rings are high-density, precision-machined cylindrical components designed for extreme thermal, electrical, and mechanical environments. Produced via advanced powder metallurgy (isostatic pressing, high-temperature sintering, and vacuum copper infiltration), these rings integrate the high heat hardness, low thermal expansion, and arc erosion resistance of tungsten with the exceptional electrical and thermal conductivity of copper.
Engineered to exact customer dimensions and drawings, these custom rings and bushings deliver outstanding concentricity, tight wall-thickness tolerances, and smooth surface finishes for seam welding wheels, high-voltage arc contacts, EDM rotary electrodes, and wear-resistant guide sleeves.
Material Composition: Available in standard and custom grades (W80Cu20, W75Cu25, W70Cu30, W50Cu50)
Manufacturing Process: Isostatic Powder Pressing -> Vacuum Sintering -> Copper Infiltration -> Precision CNC Turning & Grinding
Outer Diameter (OD): Customized per drawing specs
Inner Diameter (ID): Customized per drawing specs
Height / Width: Customized cut-to-length and precision ground
Machining Tolerance: Up to +/- 0.005 mm (Per drawing requirements)
Surface Finish: Fine turned, ground, or mirror polished (Ra 0.4 - Ra 1.6)
Custom Capabilities: Precision lathe turning, internal boring, chamfering, oil-grooving, wire EDM, and surface lapping according to 2D/3D technical drawings (PDF, STEP, CAD).

Zergatik aukeratu gaitzazu:
1. Material ezin hobea lor dezakezu zure eskakizunaren arabera ahalik eta prezio txikienean.
2. Reworks, FOB, CFR, CIF eta atez ateko bidalketa prezioak ere eskaintzen ditugu. Nahiko ekonomikoa izango den bidalketa egiteko tratua egitea gomendatzen dizugu.
3. Ematen ditugun materialak guztiz egiaztagarriak dira, lehengaien probaren ziurtagiritik azken dimentsioko adierazpenera arte. (Txostenak eskakizunen arabera erakutsiko dira)
4. bermatu erantzuna 24 orduko epean (normalean ordu berean)
5. Stock alternatibak lor ditzakezu, errota entregak fabrikazio denbora gutxituz.
6. Gure bezeroei guztiz dedikatuta gaude. Aukera guztiak aztertu ondoren zure eskakizunak betetzea ezinezkoa izango balitz, ez zaitugu engainatuko bezeroekiko harreman onak sortuko dituzten promesa faltsuak eginez.
