Evergrowing Resources Cooperation Limited was located in Nanjing, Jiangsu Province, China. We supply different kinds of industrial products and services to domestic and international customers for more than 15 years. Our main products are amorphous alloy strips, iron cores, special steel bars, Silicon steel and so on.
Amorphous alloy is a new soft magnetic material. It is known as a new material with environmental protection, energy saving and high efficiency. It is produced through an advanced technology of rapid solidification of molten metal at a cooling rate of about a million 'C/sec. Now our amorphous strip could be used to make EMC common mode inductor, current transformer core, transformer core, inductor core and so on. Amorphous ribbon has many advantages, such as high permeability, high saturated induction, high electrical resistivity, high density, low core loss and good stability. It can replace the materials of silicon steel, permalloy and ferrites, widely used in electric power, electronic products.
Additionally, we supply all kinds of special steel bars, such as rolled bars, cold drawn steel bars, forged steel bars, and tool
steel bars. And we could perform further processing according to customer's requirements such as peeling, grinding and heat treatment.
