The precision alloy mainly applies to electrical component, hard glass, soft glass, glassy-closure alloy of ceramic match sealing, soft magnetic alloy, elastic alloy, including iron, nickel, cobalt alloy 4J29, iron-chromium alloy 4J28 , iron-nickel alloy 1J36, 1J50, 1J79, 1J80, 3J9, 4J42, 4J50 etc.. The product specifications include silk, belt, pipe, sheet and rod materials. The smelting process of the alloy is undertaken in the non-vacuum induction furnace and vacuum induction furnace, the other smelting methods which can meet the requirements also can be used. Grade Chemical composition % Remarks C P S Mn Si Cu Cr Mo Ni Co Fe The chemical composition is    allowed to deviate from the    standard requirements when the    alloy magnetic is in line with the    standard. 1J36 ≤0.03 ≤ 0.020 ≤ 0.02 ≤ 0.06 ≤0.20 / 35.0 / 37.0 The remaining amount 1J50 ≤0.03 ≤ 0.020 ≤ 0.02 0.30 / 0.60 0.15 / 0.30 ≤0.20 / / 49.0 / 50.5 / The remaining amount 1J79 ≤0.03 ≤ 0.020 ≤ 0.02 0.60 / 1.10 0.30 / 0.50 ≤0.20 3.80 / 4.10 78.5 / 80.0 The remaining amount 1J80 ≤0.03 ≤ 0.020 ≤ 0.02 0.60 / 1.10 1.10 / 1.50 ≤0.20 2.60 / 3.00 / 79.0 / 81.5 / The remaining amount 3J9 0.02 / 0.26 ≤ 0.030 ≤ 0.02 1.80 / 2.20 1.3 / 1.70 19.0 / 20.5 1.60 / 1.85 9.0 / 10.5 The remaining amount 4J29 ≤0.03 ≤ 0.02 ≤ 0.02 ≤0.50 ≤0.30 ≤0.20 ≤0.20 ≤0.20 28.5 / 29.5 16.8 / 17.8 The remaining amount 4J28 ≤0.12 ≤ 0.02 ≤ 0.02 ≤1.00 ≤0.90 27.0 / 29.0 ≤0.50 The remaining amount N≤0.02 4J42 ≤0.05 ≤ 0.02 ≤ 0.02 ≤0.80 ≤0.30 41.5 / 42.5 ≤1.0 The remaining amount Al≤0.10 4J50 ≤0.05 ≤ 0.02 ≤ 0.02 ≤0.80 ≤0.30 49.5 / 50.5 The remaining amount Al≤0.10 With wide experience and expertise, Bozhong Group is one of the leading precision alloys manufacturers and suppliers.
