Karma waya yekunyepedzera(0.02mm, 0.03mm, 0.04mm)
1. Karma Alloy
Karma Alloy inogadzirwa nemhangura, Nickel, aluminium uye simbi seyakanyanya zvikamu. Upamhi ndeye 2 ~ 3 times yakakwirira kupfuura mentong. Iyo ine tembiricha yakaderera yekudzivisa Yayo yekushanda tembiricha yakasviba yakafara kupfuura mentong (-60 ~ 300ºc). Izvo zvakakodzera kuita zvakanaka zvakaringana kuramba zvinhu uye kunetseka.
2. Saizi yeKarma
Wire: 0.01mm-10mm
Ribhoni: 0.05 * 0.2mm-2.0 * 6.0mm
Strip: 0.5 *0mm-5.0 * 250mm

4. Mhedzisiro yezvimiro zveKarma Kupesana Wire
1) kutanga ne nickel chromium yemagetsi yekupisa waya kirasi 1, isu takatsiva imwe yeiyo ni ne
Al nezvimwe zvinhu, uye nekudaro zvakawana precides kudzikisira zvinhu zvine kuvandudzwa
Kupisa tembiricha inokanganisa uye kupisa extrompotive simba kurwisa mhangura.
Nekuwedzera kweAl, isu takabudirira kuita vhoriyamu kuramba 1,2 kakawanda
pane nickel chromium yemagetsi yekupisa waya wekirasi 1 uye sosi yesimba 1.3 times yakakura.
2) tembiricha yechipiri coefficient β ye karmalloy waya kmw kmw zvakanyanya, - 0.03 × 10-6 / k2,
uye kudziya kwekudziya kwekutenderera kunochinja kuva nemhete yakatwasuka mukati
tembiricha tembiricha.
Naizvozvo, tembiricha yekudziya inoiswa kuti ive yakaenzana tembiricha inoenderana pakati
23 ~ 53 ° C, asi 1 × 10-6 / k, avhareji tembiricha coefferent pakati pe 0 ~ 100 ° C, zvakare zvinogona
kutorwa kune tembiricha inoenderana.
3.
inoratidzira kugadzikana kwakanaka kwazvo kwenguva yakati wandei.
4) Kana ichi ichi ichishandiswa seyakajeka kuramba zvinhu, kupisa kupisa kupisa kurapa ndiko
inodiwa kuti ubvise kugadzirisa kusagadzikana sezvakaita mune iyo Manganin Wire Cmw.
