0Cr25Al5 Fecral u'amea/uaea fa'avevela/umu uaea fa'avevelaina
1. Fa'amatalaga
Faʻatasi ai ma uiga o le maualuga o le teteʻe, maualalo le maualalo o le eletise eletise, maualuga le vevela o le faʻaogaina, lelei le faʻafefeteina i lalo ole vevela maualuga.
E masani ona faʻaaogaina i totonu ole locomotive eletise, locomotive diesel, taʻavale metro ma le maualuga o le taavale feʻaveaʻi ma isi mea faʻapipiʻi faʻamalo taofi, kuka sima eletise, ogaumu fale gaosi oloa.
2. Fa'amatalaga
1). Locomotive resistance strip:
Mafiafia: 0.6mm-1.5mm
Lautele: 60mm-90mm
2). Fa'aeletise sima ipu fa'atete'e fasimea:
Mafiafia: 0.04mm-1.0mm
Lautele: 5mm-12mm
Mafiafia & Lautele: (0.04mm-1.0mm) × 12mm(luga)
3). Lipine maualalo:
Mafiafia & Lautele: (0.2mm-1.5mm) * 5mm
4).Ogaumu faufalelipine:
Mafiafia: 1.5mm-3.0mm
Lautele: 10mm-30mm
3. Vaega
Fa'atinoga mautu; Anti-oxidation; Tete'e o le pala; Maumau maualuga o le vevela; Lelei tele le mafai ona fausia coil; Tulaga tutusa ma matagofie i luga e aunoa ma ni ila.
4. Fa'amatalaga fa'apipi'i
Spool, coil, pusa laupapa (pei o mana'oga a le tagata o tausia)
5. Oloa ma auaunaga
1). Pasia: ISO9001 tusipasi, ma SO14001cetification;
2). Au'aunaga lelei pe a uma ona fa'atau;
3). Talia oka laiti;
4). Mea mautu i le vevela maualuga;
5). Tuuina atu vave;

0Cr25AL5 FeCrAl uaea faamafanafana
Uamea-chromium-aluminium (FeCrAl) fa'ameamea
FeCrAl alloys o loʻo faʻaalia i le sili atu o le faʻamaʻiina o le faʻamaʻiina ma le lelei tele o le faʻamautuina o foliga e mafua ai le umi o le elemene ola. E masani ona faʻaaogaina i elemene faʻavevela eletise i ogaumu fale gaosimea ma meafale.
FeCrAl alloys e maualuga atu le vevela o le auaunaga ona sosoo ai lea ma le NiCr Alloys ma sili atu le maualalo o tau. Ae e maualalo le mautu ma fetuutuunai, faigofie ona maaleale pe a uma le li'o taimi.
