Zirconium disc 8 holes Ø 150 velcro grain 36
Zirconium disc 8 holes Ø 150 velcro grain 36 for Original edge sanders, 4D multi-disc and other brands
Pack of 50
The zirconium disc, 8 holes, 150 mm diameter, 36 grit velcro, is traditionally blue, and buying a green disc is strongly discouraged. The grains on the latter are overcooked and do not adhere properly.
Zirconium is an ideal material for sanding metal. It enables faster and more efficient sanding results on materials that are difficult to treat. It is particularly effective for roughing, but it can also cause micro-scratches.
Zirconium is a chemical element represented by the symbol Zr. It is a grey-white, hard and malleable metal, mainly found in nature in the form of a mineral called zircon.
In the field of sanding, zirconium is frequently used as an abrasive material. These abrasives are generally made by mixing zirconium with other abrasive materials, then binding them with resin or rubber. However, it should be noted that there are many variants on the market containing an excessive proportion of zirconium coupled with silicon carbide, resulting in a lower sanding quality. When these discs break, the grains can no longer be resharpened.
Zirconium abrasives are valued for their ability to quickly remove materials that are difficult to sand, such as hard metals, alloys and composite materials. In addition, zirconium is highly resistant to heat and wear, making it a useful material for high-temperature sanding or for rough and resistant surfaces.
Did you know that zirconium is extremely resistant to corrosion? That is why it is widely used in various applications, including the production of nuclear reactors, pipes, sheet metal and other components for the chemical and oil and gas industries. It is also used in the manufacture of jewellery, watches and other high-end products because of its resistance to oxidation and its ability to be polished to a lasting shine.
Finally, zirconium is used in alloys, particularly with niobium, hafnium and titanium, to produce materials that are highly resistant to heat and corrosion, such as aeroplane turbines and rocket engines.
