Powerful magnet manufacturer introduce why magnet is on iron absorption

Powerful magnet manufacturer introduces why magnet is iron nickel element on the suction reserves in the world are very few, the price is very expensive. Therefore, the high content of nickel in stainless steel in the market, the price also is higher, and the magnet is not on. There is a kind of stainless steel is not on the magnet. That is less high manganese containing nickel or nickel stainless steel. The stainless steel market prices higher than nickel stainless steel per ton lower than 1000 yuan. Some businesses will use people 'good stainless steel magnet is not on the misunderstanding, to mix pin commodity, as the same quality products to sell. There are more than 100 types of stainless steel, the features and functions. Generally as a decorative sculpture austenitic stainless steel. Because of austenitic stainless steel for low heat conductivity, using it to do the kettle, frying pan is not appropriate, will be a waste of energy, and working hours. Do with ferritic stainless steel frying pan, pot, not only has excellent corrosion resistance, and its thermal conductivity is higher than austenitic stainless steel nearly half. In the washing machine barrel, water heater, xiancai basins, etc. , as long as contact with water vessels should choose ferritic stainless steel. Someone complained about the stainless steel cutlery, this is because choose the wrong stainless steel. Austenitic stainless steel hardening, not suitable for cutting tool, cutting tool. Stainless steel iron iron delicate appearance, corrosion resistance properties, deformation of the advantages of strong magnet is more and more by the vast number of consumers' hands. Articles for daily use, such as urban construction, the stainless steel material is used more and more, but the understanding of the material of stainless steel or deep enough, when some people buy stainless steel kitchen utensils and appliances, with a magnet moved on kitchen utensils and appliances. Believe magnets is iron, not stainless steel. Iron and steel is to distinguish between the carbon content. Carbon content is under 2% of the iron carbon alloy steel, carbon content in more than 2% of iron. Steel because of both the toughness, elastic, rigid is widely used. Life encounters are steel, just name is different. Whether the magnet suck up, as long as the standard, is stainless steel. Corrosion resistance of stainless steel element is chrome. Chromium content in 10. More than 5% of the steel does not rust. Smelting with different alloying elements, also had the magnets on and does not speak. Stainless steel is generally divided into austenite, ferrite and martensite, etc. If into the molten steel in the different proportion of chrome nickel, etc. , austenitic steel is tempered magnets are not on the stainless steel; If join into the molten steel chrome and a small amount of nickel, tempered steel is magnets out of stainless steel; Martensite stainless steel main alloying element is chromium, iron and carbon. Stainless steel because of the different points, there are more than 100 alloy content. In addition to the austenitic stainless steel has magnetism. Process knowledge: powerful magnet manufacturer to introduce other varieties ilmenite ore ( 钛铁矿) Its chemical formula is FeTiO3, Fe 36. 8%,Ti 36. 6%,O 31. 6%. Trigonal system. Rhombohedron crystal class. Often irregular granular, scaly or thick plate. Above 950 ℃ ilmenite with hematite completely class quality, and the like. When the temperature falls, the melt away, so the ilmenite often contains tiny scaly hematite inclusions. Ilmenite iron steel grey or black in color. Streaks of gray or black steel. Contain hematite inclusions are brown or brown red streaks. Metal - Half a metallic luster. Opaque, no cleavage. Hardness 5 ~ 6. 5, the proportion of 4 ~ 5. Weak magnetic. Ilmenite mainly appear in the ultrabasic rock, rock, alkaline rock and acid rock and metamorphic rock. Panzhihua vanadium titanium magnetite ore deposits in China, are distributed in ilmenite granular or flake between minerals such as titanium magnetite particles, or along the titanomagnetite cleavage plane into a directional wafer. Iron silicate salt ( 硅酸铁) The ore is a kind of compound salt, no certain chemical formula, the change of the composition is very big, generally appear variegated dark green, specific gravity is 3. 8 the left and right sides, iron content is very low, is a poor iron ore. Pyrites ( 铁硫化物) This kind of ore contains FeS2, containing Fe only 46. 53 to 6% and the content of S. 4%. Gray, the proportion of about 4. 95-5. 10. Thanks to this ore often contains many other precious metals such as copper, 铜) , nickel, Nickel) And zinc ( Zinc) , gold , silver Etc. , so he kind of metal smelting industry has often been used as raw material; And because it contains a lot of sulfur, so it is often used to extract the sulfur, iron into a by-product instead, so you can't called iron ore/dongguan magnet products co. , LTD. , magnets, powerful magnets, profiled magnets, magnet factory, dongguan magnet products co. , LTD
