Our company specializing in the production of high electric resistance alloy, heat-resistant steel, precision alloy, special welding wire, stainless steel materials, such as main varieties are wire, strip, round steel, flat steel, in broadband. Company has smelting, configuration of cold rolling, cold drawing, heat treatment and other production equipment, at the same time also has the spectral analysis, mechanical properties, microstructure and physical properties testing instruments. Currently has a capacity of 5000 t special alloy production capacity, and establish a set of advanced quality management system.
The company has passed ISO9001:2000 quality certification Main products of the brand and specifications: precision alloy: 1 j j46df j46 (1, 1, 1 j50, 1 j79, 1 j85, etc.), 2 (2 j11, etc.) 3 j j (3 j1, 3 j9, 3 j21-serial open-style, 3 j53, etc.) 4 j (4 j29, 4 j36, 4 j42, 4 j50, etc.) 6 j (6 j11, 6 j15, j-20, j22, 6 j40, etc.) high temperature alloy: HGH1140, HGH2132, HGH3030, HGH4033, HGH4169, HGH4145 other nickel alloy grades: Incoloy600, Inconel601, Incoloy 800 (H), 1.4529 (926) Incoloy 825 Monel400 0.03 - - on the 8th of cold drawn wire260 hot-rolled wire rod and bar 0.08-2.5 x 5-2.5-100 cold rolling strip 10 x 5-180 hot rolling strip in weak magnetic field with high permeability and low coercivity low-frequency soft magnetic materials.
Early iron nickel alloy used in telephone communication, then adopt the method of a kind of heat treatment process and vacuum smelting improve obviously the alloy properties. Iron nickel alloy containing Ni78 % in weak magnetic field of magnetic permeability between 10 and 20 times higher than silicon steel, widely used in sensitive relays, magnetic shielding, telephone and radio transformer, precision of ac and dc meter, current transformer (transformer).
To join in the iron nickel alloy molybdenum, manganese, cobalt, copper and chromium element, such as initial permeability can get more u I and maximum permeability u m ternary and quaternary iron nickel alloy. Iron nickel alloy has a narrow and steep hysteresis loop, in weak magnetic field has a large magnetic permeability and small coercive force, resistivity is not big, but it's only work is suitable for the frequency range under 1 MHZ, otherwise the eddy current loss is too big. Iron nickel alloy processing performance is good, can be made into all kinds of complex shape, size precise components.
But its magnetic is more sensitive to mechanical stress, the influence of technological factors on the magnetic is larger, such as stamping would have fallen mu b, consistency and product performance is not easy to meet. The cost of iron nickel alloy is high. The characteristics of commonly used iron nickel alloy and USES listed in the table. Iron nickel alloy in addition to the invar alloy, kovar alloy and permalloy, include the following:
(1) alloy 68 fe + 27 42 ni ni + 5 mo and fe 53 + + 5 mo, has the very high thermal expansion coefficient, bimetallic strip can be used as a thermostat, thermal converter and all kinds of temperature control device. 46 ni + fe 54
(2), known as the generation of platinum, same as the platinum expansion coefficient, good corrosion resistance, can substitute for platinum in some occasions.
(3) 42 58 fe, ni + can replace platinum wire used for vacuum seal.
(4) 36 nj + 12 cr + 52 fe, is a constant elastic alloy, hot elasticity coefficient is equal to zero, commonly used for hair clip, watch escapement and precision instrument parts. Molten ingot of legal system, the pressure processing timber.
