Nickel chrome alloy waya Ni70Cr30
Nickel chrome alloy wayaNi70Cr30
Cr30Ni70 Nichrome Alloy Eletrothermal Coil Strip, Sable Resistance Yekupisa Element,
NiCr70/30
Nickel chromium alloy ine iron resistance electrothermal high resistivity, pamusoro pemuviri pabonde zvakanaka. Pakupisa kwakanyanya uye kusimba kwakanyanya,
uye kuita kwakanaka uye kugadzirisa kungave welding zvisikwa zvakashandiswa zvakanyanya metallurgical, magetsi, mechanic zvikamu uye magetsi
maindasitiri ekugadzira ekuita heat resistance material.
NiCr Type:Cr20Ni80,Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr25Ni20 etc.Series electric flat belt, electric fire wire.
