Hey there! As a supplier of machined tungsten alloy, I often get asked about the storage requirements for this super - useful material. So, I thought I'd write this blog to share some insights on that topic.
First off, let's talk a bit about why machined tungsten alloy is so great. Tungsten alloy is known for its high density, which makes it perfect for a bunch of applications. You've got Tungsten FDG Transport Container used in the medical field to safely transport radioactive materials. There's also Tungsten Alloy Syringe and Vial Shielding that protects medical staff from radiation when handling radioactive substances. And Tungsten Alloy Pigs, which are commonly used in the oil and gas industry for counterweights and radiation shielding.
Now, let's dive into the storage requirements.
Temperature and Humidity
The temperature and humidity of the storage environment play a huge role in maintaining the quality of machined tungsten alloy. Tungsten alloy is pretty stable, but extreme conditions can still cause problems.
For temperature, it's best to store machined tungsten alloy in a place where the temperature is relatively constant. A range between 20°C - 30°C (68°F - 86°F) is ideal. If the temperature gets too high, it can cause the alloy to expand. This might not seem like a big deal at first, but over time, repeated expansion and contraction can lead to internal stresses in the material. These stresses can cause the alloy to crack or warp, which is obviously not good, especially if you're using it for precision parts.
On the other hand, extremely low temperatures can make the alloy more brittle. This means it's more likely to break if it gets bumped or dropped. So, avoid storing it in areas that are prone to freezing temperatures, like unheated warehouses in the winter.
Humidity is another important factor. High humidity can lead to corrosion on the surface of the tungsten alloy. Tungsten itself is resistant to corrosion, but the other elements in the alloy might not be. If moisture builds up on the surface, it can start a chemical reaction that eats away at the material. To prevent this, keep the relative humidity in the storage area below 60%. You can use dehumidifiers if necessary, especially in areas with naturally high humidity, like coastal regions.
Storage Location
Where you store your machined tungsten alloy matters a lot. First of all, make sure the storage area is clean. Dust and dirt can scratch the surface of the alloy, which not only affects its appearance but can also create weak points where corrosion might start.
It's also a good idea to store the alloy away from chemicals. Some chemicals can react with the alloy, causing damage. For example, strong acids or alkalis can eat through the surface and change the properties of the material. So, keep the storage area separate from areas where chemicals are stored or used.
If possible, store the machined tungsten alloy off the ground. This helps prevent it from getting wet if there's a flood or if water seeps through the floor. You can use pallets or racks to elevate the alloy. Also, make sure the storage area is well - ventilated. Good ventilation helps keep the air dry and reduces the risk of moisture buildup.
Packaging
Proper packaging is essential for storing machined tungsten alloy. When the alloy is first manufactured, it usually comes with some form of protective packaging. Don't remove this packaging until you're ready to use the alloy.
If the original packaging is damaged, replace it with a suitable alternative. You can use plastic bags or wraps to protect the alloy from dust and moisture. For larger pieces, you might want to use wooden crates or cardboard boxes. Just make sure the packaging is strong enough to protect the alloy during storage and handling.
Inside the packaging, you can also use desiccants to absorb any moisture that might get in. Silica gel packets are a common and effective desiccant. Place a few packets in the packaging with the alloy to keep it dry.
Handling During Storage
When you're moving the machined tungsten alloy in and out of storage, be careful. Don't drop or bang it around. As I mentioned earlier, the alloy can be brittle if it's exposed to low temperatures or if it has internal stresses. A hard impact can cause it to break.
Use proper lifting equipment when moving heavy pieces. Forklifts or hoists are great for moving large machined tungsten alloy parts. Make sure the equipment is in good working condition and that the operators are trained to use it safely.
If you need to stack the alloy, do it carefully. Make sure the pieces are stacked evenly and that they're stable. Uneven stacking can cause the pieces to shift and fall, which can damage the alloy and pose a safety risk.
Inspection
Regular inspection of the machined tungsten alloy during storage is crucial. Check the surface for signs of corrosion, scratches, or cracks. If you notice any problems, take action immediately.
If there's a small amount of corrosion, you might be able to clean it off with a mild abrasive. But if the corrosion is extensive, you might need to replace the piece. For scratches and cracks, assess the severity. Minor scratches might not affect the performance of the alloy, but deep cracks can be a serious problem.
Inspect the packaging as well. If the packaging is damaged, it might not be protecting the alloy properly. Replace the packaging if necessary.
Long - Term Storage
If you're planning to store the machined tungsten alloy for a long time, there are a few additional steps you can take. First, apply a protective coating to the surface of the alloy. There are special coatings available that can help prevent corrosion and protect the alloy from the elements.
You can also consider storing the alloy in a nitrogen - filled environment. Nitrogen is an inert gas, which means it doesn't react with the alloy. By filling the storage container with nitrogen, you can reduce the risk of oxidation and corrosion.
Finally, keep detailed records of the storage conditions and inspections. This will help you track the condition of the alloy over time and make sure it's still suitable for use when you need it.
In conclusion, proper storage of machined tungsten alloy is essential to maintain its quality and performance. By following these storage requirements, you can ensure that your alloy stays in good condition for as long as possible.
