Tungsten Shotgun Slugs, copper-covered lead or other material (like steel or wax) projectile, with or without a plastic tip, that may have what appears to be rifling, but these are special cuts in the slug to let it deform when passing through a tight choke, slugs are intended for use in a shotgun and often used for hunting large game, the first effective modern tungsten shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today, most tungsten shotgun slugs are designed to be fired through a choked smoothbore barrel, they must be self-stabilizing in the absence of rifling

Earlier types of slugs were also used in 4 bore guns intended for hunting dangerous African game in the 19th century, such 4 bore guns were produced in both rifled and non-rifled versions, similarly, modern shotguns have been produced with rifled barrels, or rifled choke tubes, and slugs designed to be fired from them use spin stabilization, as these specialized shotguns are far more accurate than a smoothbore gun, they also usually have a mount for an optical sight, such as a scope, many of these slugs are sub-caliber projectiles, resulting in greatly improved external ballistics performance.

As we know, Oct. 1 is a big deal to celebrate the foundation of the People's Republic of China. There will be a variety of grand ceremonies and activities, such as a great ceremonial review of troops and lighting fireworks in the evening. People will get a 7-day vacation which combines National Day holiday and two weekends on either side, which is the second longest vocation besides Spring Festival, so called “Golden Week”. Workers are available to visit their families or to travel around the country during such long holiday. All hotels, tourist attractions, trains, buses and airplanes around the country are completely packed with holidaying Chinese people.

So how are you doing during these long holiday? Did you hanging out with your friends? Did you go to ZhongShan Road to get the free Chinese national flags yesterday? As we know, Chinatungsten has one guy who is the honest fans to China’s birthday celebration activity. He is Dr. Hanns. He has insisted to host and participate in such activity for almost 15 years. Every year, when it comes to National Holiday, he and his partners come to ZhongShan Road to hand out small Chinese national flag to the passengers for free, which aims to encourage more and more people to join the patriotic activities and to arouse human being’s patriotic consciousness. Yesterday, such activity was also held in Xiamen University, which attracted so many tourists, students, etc. even foreigners. Some photos will be shared after edition finished. If you miss the opportunity to get the free Chinese national flag yesterday, you may add and follow Chinatungsten’s WeChat ID: 中钨在线, and please leave a message, then they could see whether there are still any small national flags available for you.

It requires that electrode materials should have good mechanical strength (not be out of shape after stamping), good thermostability (not be out of shape after welding), excellent thermal conductivity (not be easily heat by current) and can not be combined with the welded material (simply not be stick with the welded material). Therefore, tungsten copper could meet a criterion above. In addition, there are some description and rules in the standard of Japanese copper alloy electrode (JIS Z 3234-1999).

2. EDM Electrode

EDM (Electrical Discharge Machining) is also called as discharge machining or electric corrosion machining, which uses pulse discharging between electrodes. The principle is that the electrode and the work-piece used as two poles and put the liquid in the gap of discharge, the pulse voltage will puncture the liquid when the distance decreasing.

Tungsten matrix pellet is a collective term for small balls or pellets, often made of Tungsten, these were the original projectiles for shotguns and are still fired primarily from shotguns, although shot shells are available in many pistol calibers in a configuration called "bird shot" or "rat-shot", lead shot is also used for a variety of other purposes such as filling cavities with dense material for weight or balance, some versions may be plated with other metals, lead shot was originally made by pouring molten lead through screens into water, forming what was known as "swan shot", and, later, more economically mass-produced at higher quality using a shot tower, the method has supplanted the shot tower method since the early 1960s.

According to applications, tungsten copper electrode can be specifically divided into resistance welding electrode, EDM electrode and the electrode of high pressure discharge tube, etc.

1 .Resistance Welding Electrode

Resistance welding electrode is using thermal resistance for welding, which is produced by the pressure of electrode and current run through contact area or close area. It takes advantage of the thermal resistance to melt or model the work-piece and combined it with metal. Resistance welding can be also divided into four types, such as spot weld, caulk weld, beading weld and butt weld. The material of electrode plays a significant role in resistance welding, which can press the welding parts, supply great amount of current and promote the welding area cool down and so on.
