Ferrite Magnet is manufactured from oxide material by powder metallurgical process. Its advantages include: low-cost excellent corrosion resistance, resistance to be demagnetized etc. The normal working temperature of Ferrite Magnet is between-40C and +250C.It can be magnetized before or after assembling. Generally, Ferrite Magnet can be machined to regular shapes like segments, blocks, rings and discs etc. The normal grades for sintered Ferrite Magnets are Y10,TY25, Y30, Y30BH, Y35, etc. Advantages of Ferrite Magnet: Ferrites have isotropic characteristics, weak magnetic performance, has the same magnetic performance in any direction, multipolar magnetic charge. The main raw material of ferrite is oxides, so it is not corroded by high temperature, high humidity or chemicals (except strong acid and base); with excellent diamagnetic impedance, no flux loss before and after assembly and magnetic charging; working temperature is-40C to + 250C, poor temperature coefficient; Br temperature coefficient is-0.2% /C, 0.2% under Br, etc. per 1 Cincrease; high hardness, wire cutting and grinding; ferrite is brittle and fragile during production and transportation. magnetic requirements and good for strict working environment requirement.

Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms. The first is Sm1Co5(SmCo 1:5),which has a maximum energy product of between 14 and 24MGOe. The second and more common form is Sm2Co17(SmCo 2:17) which has a maximum energy product of between 22 and 32 MGOe. The main Sm2Co17 alloy is around 35% Samarium (Sm)and 60% Cobalt (Co)with the balance being from varying amounts of lron (Fe) Copper (Cu). Hafnium (Hf) and Zirconium (Zr). Praseodymium (Pr) may also be used. Sm1Co5 is made of only Sm and Co and has excellent corrosion resistance. â?¢ Advantages of SmCo Magnet: 1.Superior resistance to high temperature. 2. Excellent resistance to corrosion, no coating is needed for surface protecting. 3.High working temperature. 4.SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirement.

Neodymium magnets (also known as NdFeB, Neo or NIB magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging. Advantages of Sintered NdFeB Magnet : 1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temper ature; 2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet; 3. High cost performance.

We supply HMS1, HMS 2 and Cast iron, that is procured directly from scrap yards. These are processed in a manner to suit the requirement and in the ratio and composition desired by the buyer.

aluminium scrap is categorized as new scrap and old scrap New scrap arises during the manufacturing of aluminium semifabricated and final products Old scrap refers to those products collected after disposal by consumers It is the perfect product for many customers even for those with specific needs that do not need pure aluminium We supply from all over the globe and have relationships with recycling associations spread across various continents

Raw melting material - aluminum scraps, cans, engine waste etc. Output capacity - 5-30 tons/h, customized Automation - Full automatic/ half automatic (based on output requirement and investment budget Ingot type - ADC12 (7.5kg/ 10kg / customized) 1. After cleaning the oil and grease of waste aluminum, manually put it into the furnace with a forklift; 2. Ignition for melting furnace .Heat up to 680C, and input appropriate proportion of alloy elements. Heat up to 800C, melt and stir evenly, then fetch samples to the spectrometer for testing. Every lot of production need to do testing . 3. Put A tool that attracts iron into the furnace by forklift, to suck away the iron in the aluminum water. 4. Put the slag agent into Alu liquid to remove the slag. After slag removed , put the slags into Aluminum ash separation machine , and let the aluminum water and ash separate. The proportion of slag agent and aluminum liquid is 1:500 5.Open the drain valve and the aluminum water flows automatically to the ingot production line After the ingot casting is completed, the ingot stacking robot will stack the ingots, which means the production is completed.

Heavy Melting Steel (HMS): Heavy melting steel is a designation for recyclable steel. It is categorised into two major categories: HMS 1 and HMS 2. The difference between the two is HMS 1 does not contain galvanized and cast iron, whereas HMS 2 does. Because both grades guarantee a minimum piece thickness â?? at least 1/4inch (6.3mm) for HMS 1, and 1/8 in for HMS 2 â?? consignments have a high density. The typical constituents are plates, truck parts, structural items, large machinery parts, automatic parts, pipes, post consumer steel goods.
