Major products are ultra-fine conductors and laminating wires. We develop ultra-fine diamond cutting line on the basis of traditional cutting steel wire. We expand our research towards new products with high added value. Our ultra-fine conductors and laminating wires are widely applied in electronic, new energy automobile, medical apparatus and intelligent robot fields. Diamond cutting line is used in cutting of crisp and hard materials, such as, silicon and sapphire. Plate lug is used in power battery of new energy automobile.
