PRODUCT DETAILS

In order to better develop military materials in 2020, Zhejiang Songfa introduced high-end talents and carried out project integration, invested and established Zhejiang Songfa Special New Materials Co., Ltd., and at the same time comprehensively upgraded the existing tooling equipment. The company has a compound rolling mill, 20 Roll finishing mill, 950 six-high finishing mill, 23-high stretch bending and straightening machine, bell-type annealing furnace, continuous annealing furnace, pickling line and other production equipment have obtained a number of technical achievements and practical patents. The company has established an enterprise technology research and development center, which has passed ISO9001 quality management system certification, 14000 environmental management system certification, production standardization enterprise, implementation of 6S management, adheres to technology-led, scientific management as the policy; firmly based on customers, and quality With the business philosophy of centering and price as the link, we are willing to go hand in hand with domestic and foreign counterparts to create brilliant.

The company's products cover military industry, low voltage electrical appliances, decoration, communication electronics, household appliances and so on. The materials pass SGS environmental protection testing. The company is the first drafter of National Standards for Copper-Steel Composite Sheet and Strip, Chemical Analysis of Copper-Steel Composite Metals, Decoration and Decoration Copper-Steel Composite Sheet and Strip, Deep Stamping Copper-Steel Composite Sheet and Strip, and Electrical Copper-Steel Composite Sheet and Strip. The company has obtained three-level national military confidentiality certificate, GJB9001C military product quality system certification, weapons and equipment acceptance certificate, and nearly 20 invention and utility model patent certificates. The company has a self-developed bimetal composite production line. And set up a technology research and development center, with universal physical testing machine, cupping machine, metallographic analyzer and other testing equipment.

Product sales network covers the whole world.

Copper-steel composite material is a bimetallic composite material with steel as the base material and continuous coating of copper with a certain thickness on one or both sides of the steel by rolling diffusion process. This new material perfectly combines the advantages of copper and steel, making the new material have the following characteristics:

Good electrical conductivity/ good corrosion resistance/ high strength/ good formability/ good weldability/ high cost performance.
