There are so many considerations that buyers should take into account to make the right choice, like the values listed below.
Buyers should first determine the intended application of tungsten. For example, if they need tungsten for the electronics industry, they should get pure tungsten. But if they are looking for an alloy, they should get tungsten mixed with other substances to get the required density and hardness. They should also consider the state in which they want to get tungsten, whether as powder, rod, or machined part.
It is important that buyers ensure they source their tungsten from reputable suppliers who sell them pure tungsten to tungsten alloys. They need to pay attention to the tungsten content and how well it's manufactured.
Buyers have to check their potential tungsten suppliers' certifications like ISO or AS9100 in order to be sure they are working with manufacturers who have a proven record of tungsten supplied to similar industries. Moreover, tungsten comes with various grade options. Buyers have to choose the grade that is suitable for their application in order to maintain optimal efficiency.
Lastly, buyers should read reviews and ratings of their potential tungsten suppliers and manufacturers. These will give them real-life testimonials on product quality and supplier reliability. By considering all the factors above, buyers will select quality tungsten that meets their desired requirements.
The high density and strength of tungsten make it suitable for various applications. Below are some of the industries that are known to use tungsten.
The aerospace and defense industry use tungsten in the manufacturing of parts that are needed to withstand extreme conditions, such as high temperatures and pressures. Some common applications in this industry include engine components, rocket nozzles, and thermal barriers. The high melting point and strength of tungsten make these parts reliable in ultra-hot environments.
The medical industry uses tungsten in the manufacturing of tungsten electrode holders and other components needed in X-ray machines. The X-ray machines contain tungsten filaments that generate cathode rays. Moreover, tungsten's alloys are used to manufacture radiation shielding devices. These help protect medical personnel from harmful radiation exposure.
Tungsten carbide is the most popular product manufactured from tungsten. Tungsten carbide is used widely to make powerful cutting tools for various industries that need to do a lot of cutting or have abrasive materials to work with. Tungsten carbide has very high hardness and strength. Properties like these make them suitable for use in machining and mining operations.
Several products in the agricultural industry use tungsten, specifically in the tungsten carbide form. Tungsten carbide is merged with cobalt or some other binder to make tough tips for tillage, planting, and harvesting implements like plows and drills. Furthermore, tungsten's wear resistance just makes it ideal for the demanding conditions that farming tools undergo.
Tungsten is used in the fishing tackle industry to manufacture tungsten putty, which is a new and favorite sinker among anglers. Tungsten putty can be used to quickly adjust the weight in fishing rigs to help the bait sink to the desired depth. Moreover, because tungsten putty is denser than lead yet comes in smaller sizes, it will not scare away fish in the area.
For any business that needs to buy bulk tungsten, the quality and safety standards of the produced tungsten are the following factors they need to consider a lot. Below are some of the quality and safety standards to look for when purchasing bulk tungsten.
Also known as the international standards organization, they have developed many quality management standards that are widely adopted all over the world. The most relevant one for tungsten manufacturers is the ISO 9001. This is the standard for quality management systems. It ensures tungsten manufacturers have effective quality control processes that guarantee the quality and consistency of their tungsten products.
A large number of tungsten manufacturing companies follow the ASTM standards for tungsten as well. It features specifications for tungsten materials such as purity, tensile strength, and dimensional standards for tungsten rods, filaments, electrodes, and heavy alloys. These standards help ensure the consistency of tungsten products across various applications.
Moreover, the quality standards for tungsten mines involve the assessment of the ore quality, which is measured by tungsten concentration. These standards also look into the mining practices employed to ensure that the extracted ore meets necessary purity levels. The prominent certification that evaluates these standards is the ICMI.
Regarding safety, buyers must look for manufacturers or suppliers who adhere to regulations and standards for handling tungsten like OSHA. They should also ensure that manufacturers are following proper waste management practices in order to prevent environmental contamination. Furthermore, certifications and standards related to tungsten exposure like ACGIH are very important to reduce health hazards to the workers exposed to the manufacturing process.
By prioritizing adherence to quality and safety standards, buyers can rest assured that the tungsten they source meets the industry requirements and standards while promoting a safe working environment.
At times, buyers might need to look for tungsten of an exact or similar alloy to replace or service an existing one. Below are the factors that influence how to do so.
It is because tungsten alloys contain different percentages of other metals added to them, which might cause the alloy to change. Buyers should ensure that the tungsten they are purchasing has the exact chemical composition as the one they want to replace in order to maintain its functionality.
Tungsten alloys differ in the types of metals they are mixed with, such as cobalt, nickel, iron, or copper. These metals create different tungsten carbide manufacturing processes, features, and purposes. Therefore, it is very important that the tungsten alloy being purchased has the same type of tungsten alloy as the one being replaced.
Moreover, tungsten aerospace applications require different machining specifications, such as dimensions and design, depending on the job requirements. Buyers must ensure that the replacement tungsten has the exact machining specifications required for the machine to work properly. Additionally, buyers should consider the surface finish on the tungsten, as certain jobs require specific textures or coatings.
Buyers should look for replacement tungsten from the same manufacturer as the original tungsten. Because they know the manufacturer will maintain consistency in their tungsten products. If they are purchasing tungsten from a different manufacturer, ensure that the manufacturer maintains the same production standards as the original manufacturer's to avoid any variance.
For customers who are replacing tungsten, the easiest way to do so is by obtaining a serial number from the existing tungsten. The serial number is the same for any batch that is manufactured together, so it will be helpful only when the aforementioned manufacturers are using the same materials for the production process.
