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).

Kuki Duhitamo:
1. Urashobora kubona ibikoresho byuzuye ukurikije ibyo usabwa byibuze kubiciro bishoboka.
2. Turatanga kandi Reworks, FOB, CFR, CIF, n'inzugi kubiciro byo gutanga inzugi. Turagusaba gukora amasezerano yo kohereza bizaba byubukungu.
3. Ibikoresho dutanga birashobora kugenzurwa rwose, uhereye ku cyemezo cyibizamini fatizo kugeza ku ndunduro yanyuma. (Raporo izerekana kubisabwa)
4. garanti yo gutanga igisubizo mugihe cyamasaha 24 (mubisanzwe mumasaha imwe)
5. Urashobora kubona ubundi buryo bwimigabane, kugemura urusyo hamwe no kugabanya igihe cyo gukora.
6. Twiyeguriye byimazeyo abakiriya bacu. Niba bidashoboka kuzuza ibyo usabwa nyuma yo gusuzuma amahitamo yose, ntituzakuyobya dusezerana ibinyoma bizana umubano mwiza wabakiriya.
