tungsten carbide bushing with tungsten carbide powder as main raw material, at the same time with cobalt powder as binder and then mixing injection mould pressing sintered and eventually into corresponding, therefore tungsten carbide bushing with the tungsten carbide material of high hardness and high bending strength, wear resistance and corrosion resistance and its also spoke highly of by the user, widely used in various industrial fields.

In order to cater for the use of customers in different fields, tungsten carbide bushing can be made of different carbides. According to different binder, the tungsten carbide plate number is mainly divided into YG series and YN series. Generally speaking, the YG series cemented carbide bushing has higher flexural strength, while YN series cemented carbide bushing has better corrosion resistance than the former.

According to the different application ranges, we manufacture of cemented carbide liner usually has a high precision size, is also due to their high precision grinding degree, size precision, high wear resistance and corrosion resistance, tungsten carbide bushing is widely by many domestic and foreign customers praise.

In addition, due to the different use environment of cemented carbide bushing, there are several types: tungsten carbide bushing, tungsten carbide guide sleeve and tungsten carbide drill sleeve, etc. According to the customer's design drawing, we can customize the tungsten carbide liner to meet the user's different usage environment.

tungsten carbide bushing in terms of stretching, mainly some stretching, copper, stainless steel parts by using frequency is too high,it’s easy to heat, wear bushing, thus make blunt needle movement, product size error, and the bad appearance of the products.

With the improvement of oil production, the superficial surface oil reduce, in order to ensure that oil consumption of people gradually to the deep well, high Angle Wells, but gradually increased the difficulty of the drilling for oil and therefore the exploitation of oil components requirements with good wear resistance, corrosion resistance and impact resistance, etc.

tungsten carbide bushing as wear parts in the mechanical oil Wells, with high hardness, good wear resistance, smooth finish higher performance, already more and more widely applied in modern society, satisfied the need of daily and special performance. Some enterprises adopt spray welding technology to improve the durability and service life of cemented carbide bushing.

After spray welding of cemented carbide liner to HRC60 hardness, wear resistance is better, can meet the application requirements of petroleum machinery industry, but the tungsten carbide bushing need to spray after welding turning processing, in order to guarantee the size of the drawings and accuracy requirements.
