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).

Nahoana no mifidy anay:
1. Azonao atao ny mahazo ny fitaovana tonga lafatra araka ny takinao amin'ny vidiny faran'izay kely indrindra.
2. Izahay koa dia manolotra Reworks, FOB, CFR, CIF, ary ny vidin'ny fanaterana varavarana. Manoro hevitra anao izahay hanao fifanarahana amin'ny fandefasana entana izay tena ara-toekarena.
3. Ny fitaovana omenay dia azo hamarinina tanteraka, manomboka amin'ny taratasy fanamarinana ara-pitaovana manta ka hatramin'ny fanambarana farany amin'ny lafiny farany.
4. antoka hanome valiny ao anatin'ny 24 ora (matetika amin'ny ora iray ihany)
5. Afaka mahazo tahiry hafa ianao, fanaterana fitotoana miaraka amin'ny fampihenana ny fotoana famokarana.
6. Nanokan-tena tanteraka ho an'ny mpanjifanay izahay. Raha tsy azo atao ny mahafeno ny fepetra takinao rehefa avy nandinika ny safidy rehetra, dia tsy hamitaka anao amin'ny fanaovana fampanantenana diso izay hamorona fifandraisana tsara amin'ny mpanjifa.
