Our Custom Non-Standard W75Cu25 Tungsten Copper Round Bars and Discs are precision-engineered to meet specialized customer dimensions, drawings, and high-stress application requirements. Manufactured through advanced powder metallurgy (pressing, high-temperature vacuum sintering, and copper infiltration), the W75Cu25 alloy (75% Tungsten, 25% Copper) offers high density, superior thermal arc resistance, and exceptional mechanical hardness coupled with high electrical conductivity.
These custom-machined short round bars and thick discs feature a fine surface finish, uniform microstructure, and precise dimensional control, making them ideal for EDM sparking electrodes, heat dissipation substrates, high-voltage arcing contacts, and resistance welding tooling.

Çima Me Hilbijêre:
1. Hûn dikarin materyalê bêkêmasî li gorî hewcedariya xwe bi bihayê herî hindiktirîn bistînin.
2. Em Reworks, FOB, CFR, CIF, û bihayên radestkirina derî bi derî jî pêşkêş dikin. Em ji we re pêşniyar dikin ku ji bo barkirinê peymanek bikin ku dê pir aborî be.
3. Materyalên ku em pêşkêş dikin bi tevahî verastkirî ne, ji belgeya ceribandina madeya xav heya daxuyaniya pîvana paşîn. (Dê rapor li ser hewcedariyê nîşan bidin)
4. garantî dike ku di nav 24 demjimêran de bersivê bide (bi gelemperî di heman saetê de)
5. Hûn dikarin bi kêmkirina dema çêkirinê re alternatîfên stokê, radestkirina milan bistînin.
6. Em bi tevahî ji bo mişteriyên xwe ve girêdayî ne. Ger piştî vekolîna hemî vebijarkan ne gengaz be ku hûn hewcedariyên we bicîh bînin, em ê we bi dayîna sozên derewîn ên ku dê têkiliyên xerîdar ên baş biafirînin we xapînin.
