Tungsten Qws Description
Cov khoom nyoos los ua cov tungsten pas nrig yog tungsten ingot uas yog tsim los ntawm tungsten hmoov los ntawm hmoov metallurgy. Qhov tsawg kawg nkaus purity yog 99.95 feem pua. Tungsten tuaj yeem ua haujlwm los ntawm forging, kos duab, extruding thiab dov.
SSC tshwj xeeb hauv kev tsim cov purity siab zoo li tus tungsten pas nrig nrog qhov ua tau zoo tshaj plaws thiab qhov tsawg tshaj plaws qhov nruab nrab qhov ntau thiab tsawg. Peb tuaj yeem tsim tungsten rods ntawm txoj kab uas hla mus txog 100mm. Peb hais rau tshwj xeeb tsawg kam rau ua nyob rau hauv cov nqe lus ntawm ob txoj kab uas hla thiab roundness thiab lav rods ntawm exceptional straightness. Peb tseem tuaj yeem muab cov pas nrig sab nraud tus qauv ntau. Lwm cov duab muaj nyob ntawm kev thov.
Tungsten pas nrig yuav siv tau los ua emission cathode, siab kub sib sau pas nrig, kev them nyiaj yug hlau, tshuab luam ntawv tus pin, ntau yam electrode, cua sov caij ntawm quartz rauv, thiab lwm yam. Tungsten rods kuj raug foob rau daim ntaub ntawv xws li foob pob ua ntxaij, satellites, dav hlau thiab nkoj.
Peb kuj muab ntau hom tungsten alloy rods xws li tungsten npib tsib xee hlau qws, tungsten nickel tooj liab pas nrig, tooj liab tungsten pas nrig, thiab lanthanated tungsten pas nrig.
SSC tseem muaj peev xwm muab kev pabcuam machining rau ntau yam tungsten thiab tungsten alloy rods xws li tig, milling, drilling, txiav, sib koom, sib sau, sib tsoo, stamping thiab EDM machining.
