Products
Amorphous Ribbons
The strip thickness of iron-based amorphous alloy is about 0.03mm. It is widely used in power distribution transformers, high-power switching power supplies, pulse transformers, magnetic amplifiers, intermediate frequency transformers and inverter iron cores.
Amorphous strip product introduction
Amorphous alloy is a new type of energy-saving material. It is made of molten metal that is rapidly cooled at a rate of about one million degrees per second. During this process, the molten metal forms an amorphous thin ribbon with a liquid-like structure inside. It is completely different from the crystal structure of silicon steel, with high magnetic permeability and low high-frequency loss. At the same time, the production process of amorphous alloy strip is short, and the emissions of harmful gases such as CO, SO2, NOX are effectively reduced during the production process. It is a two-way energy-saving product and is known as a revolutionary progress in metallurgical processes.
BJAT Technology Co., Ltd. is one of the two companies in the world with independent intellectual property rights to produce amorphous strip, and the iron-based amorphous strip has the second largest production capacity in the world. The company has developed and mastered a number of amorphous strip production technology, equipment design and manufacturing technology, automation control technology and performance detection technology. The performance of amorphous belt products has reached the international advanced level.
Material properties
High saturation magnetic induction and high magnetic permeability-reduce the size of the device
Fe-based amorphous soft magnetic alloy can have both high saturation magnetic induction (1.56T) and high magnetic permeability (> 10000);
Low loss-reducing device temperature rise
Iron loss equivalent to 1/5 of silicon steel, loss as low as 100W / Kg at 500KT at 10KHz;
Low coercivity-improve device efficiency
Coercive force as low as 5.0A / m under static;
Low magnetic elongation-reduce device operating noise
Close to zero saturation magnetostrictive coefficient, so low operating noise;
High temperature stability
Change rate of material properties in the temperature range of -50 ℃ ~ 150 ℃ <10%
Excellent frequency characteristics
Excellent magnetic permeability and low loss over a wide frequency range;
Highly adjustable magnetic properties
Different types of magnetic properties can be obtained through the application of transverse heat, longitudinal magnetic or ordinary heat treatment with no magnetic field.
Such as low remanence type, high rectangular ratio type, high magnetic permeability type.
Anti-theft label tape
Acoustic and magnetic anti-theft system has almost zero false alarms, high detection rate, not shielded by metal foil, good anti-interference, and wide protected exit.
Application area
Acoustic-magnetic anti-theft system mainly used in large supermarkets
Performance characteristics
Most large supermarkets abroad use 58KHz acoustic and magnetic anti-theft systems. Protected goods include clothing and apparel, footwear, food, beauty and health products, hardware tools, toys and consumer electronics. The acousto-magnetic anti-theft system uses the principle of magneto-mechanical coupling. It has almost zero false alarms, high detection rate, not shielded by metal foil, good anti-interference, and wide protected exit.
