Of the Company the electric heating alloy, on the professional production of high resistance which heat-resistant steel, precision alloy, special welding wire, stainless steel and and other materials, the main varieties there are of silk build, with strip, round steel, flat steel, in broadband. The Company configured with smelting, cold-rolled, cold drawn, heat treatment and and other production equipment, at the same time also has a the spectral analysis, Chinese performance of Theoretical and Applied Mechani, metallographic and physical properties of testing instruments. With an annual output of 5000T special alloy production capacity, and the establishment of a set of advanced quality management system. The company has passed ISO9001: 2000 quality certification grades and specifications: Precision Alloy: 1J (1J46 1J46DF, 1J50, 1J79, permalloy 1J85 (PC) etc.) 2J (2J11 and so on) 3J (3J1, 3J9, 3J21, 3J53) 4J (4J29, 4J36, 4J42, 4J50) 6j (6J11, 6J15, 6J20, 6J22, 6J40) high-temperature alloys: HGH1140 HGH2132 HGH3030 HGH4033 HGH4169 HGH4145 other nickel alloy grades: Incoloy600 Inconel601, Incoloy 800 (H) Incoloy 825 Monel400 1.4529 (926) Φ0.03-- Φ8 cold drawn wire ?8 --- the Φ260 hot wire rods 0.08 --- 2.5 --- 100 cold-rolled strip 2.5 --- 10 × 5 --- 180 hot rolled strip having a weak magnetic field of the low-frequency soft magnetic material of high magnetic permeability and low coercive force. Early iron-nickel alloy used for telephone communications, method of subsequently accounted for using the one kinds of heat treatment process and vacuum smelting of the so that that characteristics of the alloy is to get much greater improve the. High the magnetic HERALD of the of nickel-containing Are Ni78% of the the iron Alloy in the the Weak Magnetic Field of the rate of than the silicon steel is of approximately 10 ~ 20 times, universal used for of the sensitive relays, magneto-Ignore, telephone and radio transformer, the Precision of the The AC and DC A Instrumentation, Current Transformer (see transformer) in the. Was added in the iron-nickel alloy, molybdenum, manganese, cobalt, copper, chromium and other elements, can have a greater initial permeability μi and the maximum magnetic permeability μm ternary and quaternary iron-nickel alloy. Iron-nickel alloy having a narrow and steep hysteresis loops in the weak magnetic field having a large magnetic permeability and a small coercive force, but its resistivity is not only suitable for work in the frequency range below 1 MHz, Otherwise, the eddy current loss is too large. Iron-nickel alloy processing performance, can be made into a variety of complex shape, the exact size requirements components. But its magnetic can be more sensitive to mechanical stress, the impact of technological factors on the magnetic properties, such as stamping causes μb decline, thus the consistency of product performance is not easy to meet. The the cost of of the iron-nickel alloy is high. The characteristics and uses of the commonly used iron-nickel alloy shown in Table. Iron-nickel alloy Invar, Kovar and permalloy, further comprising the following alloys: (1) 68Fe +27 Ni +5 Mo and 53Fe +42 Ni +5 Mo having a high thermal expansion coefficient, can be used as bimetal thermostat, the heat converter and a variety of temperature adjusting means. (2) 46Ni +54 Fe, called substituting platinum expansion coefficient the same as platinum, has good corrosion resistance, can in some cases instead of platinum. (3) 42Ni +58 Fe,, can the platinum-Replaced to to used as a the vacuum tube sealing-silk. (4) 36NJ +12 Cr +52 Fe, is a constant elastic alloys, thermo-elastic coefficient is equal to zero, often used as a hairpin, watch balance wheel and precision instrument parts. The melting ingots, the pressure processing.
