Steel fishing needles added the elements of tungsten and vanadium – with lighter weight, harder and sharper. This is the first time that tungsten and vanadium elements have been introduced into fishing needles, and the advent of this technology will bring about a milestone change in the fishing needle industry. Undoubtedly, this type of fishing needle is harder and more wear-resistant than the fishing needle made of ordinary steel wire. What's more, this number of fishing needles is available to meet the different needs of competition and black pit. The breakthrough of the W element and the V element into the fishing needle manufacturing, so that its performance is improved from the aspects of strength, sharpness, wear resistance and light weight, and its lightweight characteristics should respond to the advantages of light fishing.

In the process of preparation of tungsten products and elimination of waste products, a large number of secondary resources containing tungsten will be formed. Recovering tungsten from secondary resources will not only improve the quality of tungsten, but also realize resource recycling. At present, the recovery and utilization of tungsten slag is mainly divided into three parts: (1) recovering valuable metals; (2) using tungsten slag as mineral material to produce wear-resistant materials; (3) producing tungsten slag glass-ceramics.

Are you in the heat of the northern hemisphere? Still in a corner of the southern hemisphere? No matter how! When you turn around, you will always rotate again! Then, it should always meet the studs on the car tires. After all, the studs will always appear in cold and humid areas. Tungsten carbide studs are mainly embedded in car tires to prevent the car from slipping on wet skating surfaces and have a very broad market in many European countries.

Graphene is a new kind of carbon material, which is closely packed with carbon atoms into a single two-dimensional honeycomb lattice structure. It is the basic unit of building the most commonly used solid lubricant - graphite. It has lower friction coefficient than graphite. It is a new kind of additive for self-lubricating antiwear coating.
