R60702 Zirconium RodWire Solution for IndustrialLaboratory Use

R60702 material zirconium rod/wire refers to rod-shaped and filamentous profile products processed from R60702 grade zirconium alloy through multiple processes such as vacuum melting, forging, hot rolling, and drawing (usually, diameter ＞ 1.0mm is rod, and diameter ≤ 1.0mm is wire). They are mainly used in scenarios such as chemical anti-corrosion fasteners, aerospace structural components, electronic component electrodes, laboratory precision devices, and medical device accessories. As a classic pure zirconium-based alloy grade, R60702 relies on excellent high-temperature resistance (can work stably below 800℃ for a long time and withstand 1000℃ high temperature for a short time), outstanding corrosion resistance (has extremely strong resistance to most acids, alkalis, salts, molten metals and high-temperature gases, especially stable in strong corrosive chemical media), as well as the characteristics of pure material without impurity pollution and balanced mechanical properties. It has become a core material in fields with extremely high requirements for material strength, dimensional precision and environmental resistance, especially suitable for the use needs of rod and wire profiles, high precision and strong corrosive environments.

Characteristics

Excellent High-Temperature Resistance

R60702 zirconium alloy has a melting point of up to 1852℃, can work stably below 800℃ for a long time, and withstand 1000℃ high temperature for a short time. It can still maintain good mechanical properties and corrosion resistance in high-temperature environments, adapting to medium and high-temperature working conditions.

Extreme Corrosion Resistance

Strong acids (including most strong acids except hydrofluoric acid), strong alkalis, molten salts, high-temperature oxidizing atmospheres, and different molten metals are among the hostile settings in which it exhibits exceptionally strong stability. For rod and wire profile applications in highly corrosive environments, the dense oxide film that forms on the surface can successfully resist corrosion and not contaminate the contact medium.

Pure Material Without Impurities

Follows R60702 grade standard, total Zr+Hf content ≥99.2%, extremely low impurity content, will not chemically react with contact materials, ensuring product use safety and stability, especially suitable for high-precision electronics, laboratories and other scenarios with strict requirements on material purity.

Outstanding Mechanical Properties

It is tough and strong. While soft state products have superior ductility and toughness, hard state products are strong and stiff. It can adjust to the various requirements of various situations for material mechanical qualities; in particular, zirconium wire's winding and bending performance is exceptional.

High-Precision Dimensional Control

The diameter and length tolerances are incredibly small, the straightness is high, and the dimensional consistency is good thanks to precision drawing, hot rolling, and finishing straightening procedures. It can enhance the performance stability of final goods and precisely fit the assembling requirements of high-end equipment.

Good Surface Quality

Different surface finish requirements can be achieved through various surface treatment processes. The surface has no oxide scale, no scratches and no impurities, which not only improves corrosion resistance, but also meets the high-end surface appearance requirements of electronics, optics, medical devices and other fields.

Production Process

Raw Material Preparation: High-purity sponge zirconium is extracted from zircon sand by mineral processing, chlorination, and reduction procedures. This zirconium is then repeatedly melted in a vacuum arc furnace to create zirconium ingots that satisfy R60702 grade requirements (uniform composition and qualified impurity content).
Forging Processing: The zirconium ingot is heated to a specific temperature and then forged to refine grains, eliminate internal defects of the ingot, improve material density, and roll into rod-shaped blanks.
Hot Rolling/Drawing Processing: The forged blanks are treated in accordance with the final product parameters (rod/wire). While zirconium wires are drawn into blanks near the finished product diameter using several drawing processes based on hot rolling, with exact control over the amount of deformation in each pass to guarantee dimensional accuracy, zirconium rods are rolled into blanks near the finished product diameter using a hot rolling process.
Intermediate Annealing: In order to remove processing internal stress, restore material plasticity, and prevent cracking, breaking, and other issues in later processing, intermediate annealing is inserted throughout the hot rolling/drawing process.

Finished Product Annealing: The hot-rolled or drawn zirconium rods and wires are subjected to finished product annealing treatment in accordance with the processing condition required by the customer (soft state, hard state). The annealing temperature and holding time are precisely controlled to guarantee that the material performance satisfies the requirements.
Surface Treatment: The annealed zirconium rods/wires are subjected to surface treatment, which can choose pickling (removing oxide scale), bright annealing (improving surface finish) or polishing (achieving high mirror effect) to ensure surface quality.
Finishing and Inspection: In order to ensure that the final products meet R60702 grade standards and customer requirements, they undergo finishing straightening, cutting, and winding. After that, they undergo stringent inspection, including composition re-inspection, dimensional precision inspection, surface quality inspection, mechanical performance inspection, straightness inspection, etc., with a material inspection report and quality certificate attached.
