Rare Earth of Tungsten and Molybdenum on the Tokyo Olympic Games

Rare Earth of Tungsten and Molybdenum on the Tokyo Olympic Games

The Tokyo Olympic which was put off a year because of the coronavirus epidemic,was eventually held on July 23,2021.For the Chinese athletes,Chinese manufacturers made much contributions. about the half of the match equipment is made by the Chinese manufactures.the following equipment are connected with the rare earth.

1.Golf  Head

Tungsten alloy with high specific gravity is the preferred material for the counterweight of top-grade golf head,because it can lower the center of gravity and improve the balance of the club,which is beneficial to better control the hitting direction and distance.In addition,tungsten alloy has the advantages of corrosion resistance, oxidation resistance and so on,and can strength the durable property of products.

2.Tennis  Racket

Tennis racket counterweight block is mainly made from the environment-friendly and non-toxic tungsten alloy material,installed on the edge of the tennis racket to change balance,which can improve the hitting accuracy and speed and force.

3.Bow  and  Arrow

In order to ensure the stability and safety during the flight,the resistance of arrow in the air must be little and the penetration is weak.Compared with the lead and iron,tungsten steel is more suitable for making arrowhead,Because it is not only eco-friendly,but also has the higher density.

Besides the above sport equipment,the tungsten material also is used in the basketball stands,barbell,lead ball,loudspeaker,and other sport equipment and electronic instruments on the Tokyo Olympic games .Tungsten contact is an important part of the switch, which can be connected or broken.Tungsten copper alloy is used in the chip of the  electronic instruments.
