High-strength and high-conductivity copper material

1. This technology has discovered the reasons that limit the strength of high-strength and high-conductivity copper materials from the material principle, and has made breakthroughs in the scientific principles of material composition and organizational design. The manufactured products have higher strength and heat resistance than foreign high-end products, and the conductivity The rate remains at the same level.

     2. Introduce the vacuum casting technology of large-size ingots into production, and realize the mass production and supply of large-tonnage (single ingot weight 1-50 tons) and large-size chromium (zirconium) copper series products.

     3. Using vacuum melting technology, it has higher compactness than similar foreign products, and has obvious advantages in controlling defects such as pores, inclusions, and looseness.
