Products
Soft magnetic core
Soft magnetic products mainly include: wound core, punched core, and yoke.
Products are widely used in various leakage protectors, precision current (voltage) transformers, various types of electromagnetic signal conversion and amplifiers.
Soft magnetic alloy
Soft magnetic alloys are a type of alloys that have high permeability and low coercivity in a weak magnetic field. This type of alloy is widely used in the radio electronics industry, precision instruments, remote control and automatic control systems. It is mainly used for energy conversion and information processing. It is an important material in the national economy.
Corrosion-resistant soft magnetic alloy
Rectangular hysteresis loop soft magnetic alloy
Constant magnetic permeability soft magnetic alloy
High hardness, high resistance and high permeability alloy

Permanent magnet alloy
Permanent magnetic alloy is a material with a large magnetic energy product. That is, it is required to have a large hysteresis loop area, high coercive force and residual magnetic induction, and a large demagnetization curve convexity coefficient. At the same time, it has a stable structure, the magnetic properties do not change with time, and the residual magnetic induction does not decrease with external magnetic field, temperature, mechanical vibration, irradiation, etc. The permanent magnet alloys produced by our hospital include iron-cobalt-vanadium alloys, hysteresis alloys, and cast aluminum-nickel-cobalt alloys.

Thermobimetal Strips
Thermobimetal is a kind of composite material which consists of two or more layers and each layer is provided with a different expansion coefficient. The layer which possesses higher expansion coefficient is called the master layer. The layer which possesses lower expansion coefficient is called the passive layer. The layer between them is called buffer layer which acts as an adjusting resistance. Thermobimetal strip will be bended or turned because of their different expansion coefficients while the ambient temperature changes. Thermobimetal is mainly applied for manufacturing temperature sensing elements in automatic control equipments and instruments for temperature control, temperature compensation, current restriction and temperature indication.
Layered metal composite materials:
New energy vehicle lithium battery connection / contact sheet materials, integrated circuit lead frame metal composite materials, 5G mobile phone heat sink and mid-plate metal composite materials, vacuum glass support metal composite materials
High resistance heating alloys
High resistance heating alloys are characterized by high electrical resistivity, low temperature coefficient, good resistance to corrosion and oxidization as well as good linearity of resistance versus temperature.
Superalloys
Superalloys are indispensable in aviation, navigation, war industry and so on. BJBY is one of the earlier manufacturers in China for developing and producing superalloys. The as-cast master superalloy is one of our main products. It can be used for making turbine laminas , guide laminas, and other heat resistance components. The superalloys are available in forms of as-cast and deforming.
