Lead Free Tungsten Radiation Shielding

Radiation can serve useful purposes in fields such as medical diagnostics and treatments or power generation. Radiation can also be harmful to our bodies if we are exposed to it in high concentrations. It is associated with cancer and causing damage to our cells. In order to be kept safe from the damaging effects of radiation when it is used we need to be properly shielded from it. Tungsten is an excellent material for radiation shielding because it has an extremely high density. At 19.3 g/cm3 tungsten is among the most dense of all the metals. This property helps it to act as a barrier to damaging x-rays, gamma rays and other types of radiation.

Buffalo Tungsten is a manufacturer of the high density tungsten powders that are used in radiation shielding for various industries. The tungsten powder is typically compounded with rubber or plastic in order to mold it into different shapes. A commonly known medical application is the aprons and vests worn when you have an X-ray taken at a doctor or dentist's office. Our tungsten powders are also used in radiation shielding for power generation applications such as nuclear reactors. Tungsten will help shield the pipes that run to and from the reactor. These products have been traditionally made of lead, but the toxicity of lead has made the safe disposal of it expensive. With a higher density, thinner and less bulky shielding products can be produced from tungsten.

When tungsten is used it is often referred to as lead free shielding, which has formed an increasing segment of the market. Some examples of lead free radiation shielding are manufactured by companies such as Lancs Industries. If you manufacture any type of lead free radiation shielding products Buffalo Tungsten can supply the tungsten powder materials that you need.

Electrical Contacts

Buffalo Tungsten has been supplying tungsten powder for electrical contacts for over two decades. Contacts are the metallic points that come together to complete a circuit. When they are in contact, electricity can flow through them. When they are not in contact, the flow of electricity stops.

Circuit breakers are a common household example of electrical contacts. There are also many commercial and industrial uses for tungsten contacts. In other common products they are on motors in appliances. They are also on relays and switches for control systems.

Electrical contacts are typically made from a highly conductive metal such as silver or copper. These metals blend with tungsten powder to improve their resistance to wear and oxidation. Tungsten carbide powder is in various types of contacts as well. The high melting point of tungsten provides some protection from high temperatures.

Manufacturers press and sinter the contacts into their shape. The quality of the tungsten powder has a large impact on the quality of the finished products. Be sure to get tungsten powder for contacts to get the best results.


Contact us for more information about tungsten materials that can improve the performance of your electrical contacts. With many years in the industry we have seen many product applications.

Small Business Designation

It has been said that best things come in small packages, and at Buffalo Tungsten we believe it's true. By the standards of the U.S. Small Business Association, Buffalo Tungsten is classified as a small business. While we are large enough to supply full containers or truckloads of material, we are small enough to provide a high level of flexibility and customer service.

Buffalo Tungsten is small enough to maintain a sole focus on producing tungsten powder, tungsten carbide powder, and thermal spray powders. This is all that we do 24/7, so after more than thirty years we have become experts. 


We are an independent producer and are not in competition with our customers, so all of our technical knowledge goes to helping our customers make the best products possible from our tungsten materials.


Since we are small we can provide personal service and interaction with the people who are on the front lines in the factory. You will speak with someone who can walk a few steps and adjust a machine or process to help you get the changes you need immediately.


We have the flexibility to adapt to changing needs in the marketplace. Decisions are still made at the lunch table and not in a board room, so we are always willing to try new things and make changes to improve our products.


Being small allows us participate in SBA contracting programs. Buffalo Tungsten qualifies for small business set asides for U.S federal government contracting purposes.

Made in America

If you have a need to source tungsten powder products that are Made in America, Buffalo Tungsten would love to be your supplier. We provide a high quality, competitively priced alternative to foreign sources. Buffalo Tungsten has only one location and all of our operations are in Western New York. We are one of a very small group of companies that can supply tungsten powder and tungsten carbide powders that are truly Made in America.


There are companies that import tungsten powder from other countries and sell them in the United States. Just because materials are repackaged and sold by a US company does not mean that it originated in the United States. If the products have not undergone a substantial transformation (e.g. chemical reaction) they maintain the origin of the country in which they were produced. For example, if you purchase material from a US trading company that imports tungsten powder from China, there is a good chance that you are not using material that is Made in America.


It is true that we bring in raw materials such as tungsten ores and concentrates from other countries because there are no active tungsten mines in America to meet the demand in our country. However, the materials that we import undergo a substantial transformation to tungsten powder through chemical reactions that alter their composition and use. This allows us to issue a Certificate of Origin listing the United States of America as the country of origin. A very basic overview of our process shows some of the transformations that take place.

If you need confidence that your tungsten and tungsten carbide powder products are Made in America, look no further than Buffalo Tungsten to meet you needs!

Just-in-Time (JIT) Inventory Systems

At Buffalo Tungsten, we are committed to providing the level of quality, reliability, and responsiveness that our customers need to make a JIT system possible if they so choose. As a U.S.-based producer, we can offer our North American customers especially short lead times that allow us to quickly respond when their systems demand tungsten powders. If you’re a user of tungsten powder looking to implement a JIT system, or just to reduce your inventory levels, contact us today to discuss how we can be the reliable supplier your company needs. The Just-in-Time inventory system has become increasingly common in the business world in recent years. JIT is a “demand-pull” system in which each component in a production line is only produced as needed by the next stage in the process. Demand triggers each step of the production cycle (Datar & Rajan, 2018). The goal of JIT is to minimize inventory and carrying costs, freeing up capital for other uses. References: Banton, Caroline.

Social Distancing Logo

Buffalo Tungsten has created a social distancing logo with a message of hope...

Our creation of this logo is a reminder that social distancing will help us to slow the spread of a deadly virus. It threatens the lives of many, especially those who are elderly and immune compromised.

Although there are bigger issues in our world at this time we remain ready to supply tungsten powder. Our customers manufacture essential products in the medical and defense industries.

Our hope is that this virus will pass soon and we will be back to our normal activities. In the meantime we will do our part to prevent further outbreaks. We will educate our employees and adjust the work conditions to allow for more social distancing.

These are temporary measures. The world has seen pandemics before and come through. With advances in medical research we are in better shape than ever before to deal with it.

It's a time to stay home where possible. We will slow the spread and then we can enjoy time together once again. If we are all patient and be careful we will get through this faster. If we work together we will be stronger for it in the end.

Operating at Capacity

Buffalo Tungsten produces essential materials and continues to operate at normal capacity during the outbreak of the SARS-CoV-2 coronavirus. You can be assured that we can continue to meet your demand for tungsten materials.

Although we have an exemption from New York State to remain in operation, we are not conducting business a usual in many respects. We have taken steps to monitor the evolving risk and safeguard our employees and their families. We have educated our workforce on the best ways to avoid exposure to the virus and prevent spreading the virus to others. We have limited physical interactions between employees, made additional personal protective equipment available, and increased the frequency of sanitizing our facility to mitigate risk.

New York State has taken measures to reduce the community spread of the virus by requiring non-essential businesses to “reduce the in-person workforce at each business/work location by 100%...” Exemptions have been made for what are deemed to be essential businesses which allow Buffalo Tungsten to continue to operate.

We pray for the safety of our suppliers and customers and their families during the spread of this virus and the COVID-19 disease. We have faith that it will soon pass and we will be in a stronger position to face future threats.
