ECoCr-B (Kobalt 12) Kobalt Hardfacing & Wear-resistant Welding Electrode
Tipe Paduan: A5.13, Elektroda SOLID Surfaceing lan Batang Welding, A5.13
ECoCr-B Cobalt Alloy 12 bisa dianggep minangka paduan penengah antarane Cobalt Alloy 6 lan Cobalt Alloy 1. Isine fraksi hard, brittle carbide sing luwih dhuwur tinimbang Cobalt Alloy 6, lan nambah resistensi kanggo erosi sudut rendah, abrasi, lan abot. nyandhang ngusapake nalika nahan impact cukup lan resistance cavitation.Kobalt Alloy 12 asring digunakake dhewe utawa mlaku nglawan Cobalt Alloy 6 utawa 1. Isi tungsten sing luwih dhuwur nyedhiyakake sifat suhu dhuwur sing luwih apik tinimbang Cobalt Alloy 6, lan bisa digunakake ing suhu nganti 700⁰C.Kobalt Alloy 12 biasane digunakake kanggo alat nglereni sing kudu tahan abrasion, panas lan karat.
