R60705 Zirconium-Niobium Alloy
The melting point of UNS R60705 Zirconium Round Bar is 1852 degrees Celsius. High temperature and corrosion resistance is used in the production of crucibles, ceramics, abrasives and bricks. Zirconium oxides, also known as zirconium oxide, are used as opacifiers in enamels and pigments.
ASTM B493 Zirconium 702 Bars
Zirconium 702 fasteners (ASTM B493), also known as UNS R60702, are reactive metals that have a high affinity for oxygen and form a protective oxide layer in air at room temperature. The oxide protective layer gives zirconium alloys universal corrosion resistance.
Zirconium Alloys UNS R60704 Bar
Zirconium 704 round bars are suitable for different applications by direct drawing without intermediate annealing. Although Zirconium 704 round bar still has many of the properties of other grades, thanks to the addition of titanium, Zirconium 704 does not precipitate even after prolonged exposure to high temperatures.

Extracting and Preparing the Raw Material
The first step in making zirconium alloy is to extract zirconium from the mineral called zircon (ZrSiO4). This mineral is mined in places like Australia and South Africa. Once the zircon is mined, it is crushed into a fine powder to prepare it for further processing.
To separate zirconium from other materials in the zircon, a method called froth flotation is used. In this process, chemicals are added to create bubbles that attach to zirconium particles, making it easier to separate them from impurities. The result is a concentrated zirconium product, which is then heated (roasted) to remove more unwanted materials like iron and titanium.
Purifying the Zirconium
After extracting and preparing the zirconium concentrate, the next step is to purify it. This is important because zirconium naturally contains another element called hafnium, which must be removed for many applications, especially in nuclear reactors.
Creating the Zirconium Alloy
Once the zirconium is purified, it's time to turn it into an alloy. An alloy is a mixture of metals, and zirconium alloys often include small amounts of metals like tin, niobium, iron, or chromium. Adding these metals improves the strength, resistance to corrosion, and ability to withstand high temperatures.
Shaping the Alloy
The zirconium alloy ingots are then shaped into the desired forms, such as rods, tubes, or sheets.
Heat Treatment and Surface Finishing
Once the alloy is shaped, it undergoes heat treatment to enhance its properties.
Quality Control and Testing
Throughout the manufacturing process, rigorous quality checks are essential to ensure the alloy meets the required standards.
Usage of Zirconium Alloy
Aerospace
Aircraft frames, engine parts, and structural elements benefit from the enhanced ductility and durability zirconium provides, facilitating the manufacturing of lighter yet stronger aerospace vehicles.
Automotive
Aluminum-zirconium alloys contribute to automotive performance and safety by strengthening critical components, such as chassis, engine blocks, and crash-resistant structures. Notably, this allows for weight reduction without compromising safety standards — a key factor in fuel efficiency.
Nuclear
Aluminum-zirconium alloys play a vital role in nuclear reactors, thanks to their ability to withstand high radiation and extreme temperatures. Cladding, structural supports, and containment systems all benefit from the exceptional durability and resistance offered by zirconium, contributing to the safety and efficiency of nuclear power generation.
Once the alloy is shaped, it undergoes heat treatment to enhance its properties. Heat treatment involves:
Annealing: Heating the alloy and then slowly cooling it to remove internal stresses and make it stronger.
Quenching: Rapidly cooling the alloy after heating to lock in certain properties, like hardness.
Surface finishing processes are also applied to improve the alloy's resistance to corrosion and give it a clean, polished appearance. Techniques like polishing and pickling (using acid to clean the surface) are commonly used.
