Contact: Chen Ou Tel 0769 -81555080 / 13686003530 Fax :0769-81550850 Qq: 599957388 The company specializes in the production of high electric resistance alloy, heat-resistant steel, precision alloy, special wire, stainless steel and other materials, the main varieties of wire, with timber, round, flat, medium broadband. The company is equipped with smelting, rolling, drawing, heat treatment and other production equipment, but also has a spectral analysis, mechanical properties, microstructure and physical properties testing equipment. With an annual production capacity of 5000T special alloy, and the establishment of a set of advanced quality management system. The company has passed ISO9001: 2000 quality certification main product grades and specifications: Precision Alloys: 1J (1J46, 1J46DF, 1J50, 1J79, 1J85, etc.) 2J (2J11, etc.) 3J (3J1, 3J9, 3J21, 3J53, etc.) 4J (4J29, 4J36, 4J42, 4J50, etc.) 6J (6J11, 6J15, 6J20, 6J22, 6J40, etc.) high-temperature alloys: HGH1140, HGH2132, HGH3030, HGH4033, HGH4169, HGH4145 and other nickel alloys grades: Incoloy600, Inconel601, Incoloy 800 (H), Incoloy 825 Monel400 1.4529 (926) Φ0.03-- Φ8 cold-drawn wire Φ8 --- Φ260 hot rod, bar 0.08 --- 2.5 × 5 --- 100 cold rolled strip 2.5 --- 10 × 5 --- 180 one kinds of hot-rolled strip in a weak magnetic field having a high magnetic permeability and low coercive force frequency soft magnetic material. Early iron-nickel alloy used for telephone communications, and then use a vacuum heat treatment of the alloy smelting method of characteristics are greatly improved. Containing Ni78% of the iron-nickel alloy in a weak magnetic field the magnetic conductivity than silicon about 10 to 20 times, widely used sensitive relays, magnetic shielding, telephone and radio transformers, AC and DC precision instrument, current transformers (see transformer) in. The iron-nickel alloy by adding 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 alloys. Iron-nickel alloy having a steep narrow hysteresis loop, the weak magnetic field having a large magnetic permeability and a small coercive force, but its resistivity is not only suitable for frequencies below 1 MHz range, and Otherwise, the eddy current loss is too large. Iron-nickel alloy processing performance, can be made into a variety of complex shape, size, requires accurate components. But its magnetic properties are sensitive to mechanical stress, process factors greater impact on the magnetic properties, such as stamping will μb decline, which is not easy to meet product performance consistency. The high cost of iron-nickel alloy. Common characteristics of the iron-nickel alloy, and for the purposes listed in the table. Apart from iron-nickel alloy Invar, Kovar and permalloy, but also include the following alloys: (1) 68Fe +27 Ni +5 Mo and 53Fe +42 Ni +5 Mo, has a high thermal expansion coefficient, can be used bimetal thermostat, heat exchanger, and a variety of temperature adjusting means. (2) 46Ni +54 Fe, called on behalf of platinum, platinum same coefficient of expansion, has good corrosion resistance, in some cases can be used instead of platinum. (3) 42Ni +58 Fe, vacuum sealing can be used instead of platinum wire. (4) 36NJ +12 Cr +52 Fe, is a constant elastic alloys, thermo-elastic coefficient is equal to zero, commonly used for hair clips, watches balance wheel and precision instrument parts. Melting ingots, pressure processing.
