ZR705 UNS R60705 Zirconium Alloy Wire For For Heat Exchanger

ZR705 UNS R60705 Zirconium Alloy Wire For For Heat Exchanger

Zirconium alloy wire is an active metal, and an oxide film is formed at room temperature. This oxide film makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, making it an excellent corrosion-resistant structural material in today's petrochemical industry.

Product characteristics of Zirconium Alloy Wire

Zirconium alloy wire has excellent corrosion resistance. It has very good corrosion resistance to most organic acids, inorganic acids, strong alkalis and some molten salts. Hydrochloric acid, nitric acid and organic acid at nearly 100 ℃ have no effect on zirconium. The corrosion resistance of zirconium in alkali is better than that of titanium, tantalum, niobium and stainless steel, and has good heat resistance and processability. Therefore, zirconium has been widely used in industry and chemical industry

Product use of Zirconium Alloy Wire

It is mainly used in pressure vessel, petrochemical industry, aerospace, marine engineering, hydrogenation reactor and other fields.
