Fecral Alloy 0CR21al6nB Spiral Electric Hiln Pemanasan Unsur Pemanas Coil
Fecral Alloy 0CR21al6nB Spiral Electric Hiln Pemanasan Unsur Pemanas Coil
0cr21al6nBApa aloi wesi-kromium-aloi-aluminium (aloi fecral) kanggo digunakake ing suhu nganti 1350 ° C (2550 ° F). Aloi kanthi karakteristik resensi dhuwur, koefisien resistensi listrik, suhu operasi dhuwur, resistensi oksidasi sing apik ing suhu sing dhuwur. Bisa padha karo Kanthal A1, Resistohm 145, ALUCOMM0, Alchrome875, MWS-875, stablohm875.
Iki digunakake ing tungku listrik industri, peralatan listrik ing omah lan piranti sinar inframerah sing adoh.
Kayata pemanis panel, pemanas inframerah, piring pemanasan, pemanas, cilek-irahan, para pengeboran keramik kanggo masak piring, ing hobi keramik sing dienggo nganggo hobi keramik lan sapanunggalane.
