About Us

Changzhou Liduo Alloy Materials Co., Ltd. was founded in 1999. Liduo is a subordinate reorganized enterprise which belong to Changzhou Lianhuan Group (one of the national sophomore-oriented enterprises, founded in 1958). Liduo covers an area of 6275 square meters, and building area of 10551 square meters.

Liduo always adheres to scientific and technological innovation. Through continuous technological remolding and new product research work, Liduo constantly adjusts product mix and improves product technical content, and thus takes the lead in domestic field of fine alloy wires, and makes contribution to national defense industries such as aerospace, weapons, nuclear, electronics and cutting-edge instrumentation. Liduo different kinds of high performance heating wires have been widely applied in seat heaters for domestic automotive manufacturers. Liduo’s silver plating or tinned copper or copper alloy wires have achieved the matching with Taiwan Honghai, Japan Simitomo and other world-renowned enterprises. Flux used for enameled alumium wire fill the domestic blank in China and became a necessity product for enameled alumium wire to replace traditional enameled copper wire, which has been recognized by large-scale enterprises as Samsung, Haier, Midea, Galanz, etc. A number of new-developed products were identified as high-tech products by science and technology Department of Jiangsu province and the science and technology bureau in Changzhou city. Now they have become the best alternative among many enterprises to pursue the high class, to reduce cost, or to replace imported wires. High performance lead wires for speakers and high-strength high-conductivity copper alloy wires for finest coaxial cables were funded as National Science and Technology Department's Innovation Products in 2002 and 2009 respectively. Liduo has six authorized patents, including one patent for invention; Ever since 2004, Liduo has been continuously rated as Hi-Tech Enterprise in Jiangsu province.

As a high-tech enterprise, Liduo always adhere to the scientific and technological innovation as our guide and to assist the customer development as a supplier's mission. According to customers’ requirement “Change, fast and cost-effective”, Liduo is doing researches and deployments along the direction of “special conductors of very fine specifications with high bending resistance and high reliability”. With efforts to becoming an outstanding supplier of precise alloy wires and heating wires for auto seats, and an integrated supplier of special conductors for vehicle wires, medical electronic wires and robot wires, Liduo is looking forward to becoming a long-term strategic cooperation partner with customers by offering the best matching and best services for customers.
