4, Functional advantages and characteristics

Good corrosion resistance: A very strong oxide film is formed on the surface of the zirconium wire, which can effectively protect its interior from corrosion, so it has very good corrosion resistance.

High strength: Zirconium wire has high tensile strength and yield strength, so it performs very well in occasions that need to bear a certain load.

Good plasticity: zirconium wire is easy to process and shape, can be made into products of various shapes, and can achieve high-precision processing.

Non-toxic and harmless: zirconium wire is very suitable for medical, food and other industries, because it is a non-toxic, odorless and harmless material that meets environmental protection requirements.

Good radiation resistance: Compared with other metals, zirconium wire has higher density and better radiation resistance, so it is widely used in nuclear power plants and other fields.

5, Application and Precautions

Application field

Zirconium wire is widely used in petrochemical, nuclear industry, aerospace, acid equipment, chemical reaction equipment, high pressure vessels, pipelines and other fields.

Precautions

(1) Zirconium wire is easy to absorb oxygen and nitrogen, so it needs to avoid air pollution during processing, storage and transportation.

(2) Zirconium wire is prone to oxide film at high temperature, which may lead to quality degradation or affect the molding effect.

(3) Zirconium wire needs special protective measures during processing and use to avoid scratching or damaging the oxide film on the surface.
