BISMUTH (Bi)
Bismuth is used in foundries to improve machinability, reduce shrinkage, and serve as a non-toxic alternative to lead in both ferrous and non-ferrous castings, enhancing casting quality and safety.
Iron Applications – Incorporated in select inoculant formulations at concentrations of 0.5–1.0%, Bismuth helps reduce chill depth and enhances graphite nucleation, leading to improved casting structure and consistency.
Non-Ferrous Applications – Used to improve machinability and reduce brittleness in copper-based alloys, Bismuth also serves as an effective, non-toxic alternative to lead in various alloy systems.
Bismuth (Bi) – High-Purity Metal for Iron & Non-Ferrous Foundry Applications
Bismuth (Bi) is a non-toxic, heavy metal known for its unique properties, making it a valuable alloying and metallurgical additive in foundry operations. Ideal for use in both iron and non-ferrous foundry applications, offering reliable performance in a wide range of casting environments.
In iron foundries, Bismuth is commonly used as an inoculant or alloying element in compacted graphite and gray iron. It enhances machinability and promotes uniform graphite formation, improving casting consistency and surface quality. Bi can also replace lead in certain formulations, providing a safer alternative that complies with increasingly strict environmental and health regulations.
In non-ferrous foundries, Bismuth is widely used in low-melting alloys, brass and bronze systems, and fusible alloys for safety devices and precision casting. Its expansion upon solidification makes it useful in applications requiring tight dimensional control. Additionally, Bi contributes to improved castability and reduced porosity in various alloy systems.

About Us
Carpenter Brothers, Inc. is the leading supplier of equipment, consumables, and technical expertise for the metal casting industry. Founded in 1917, by Everett and Milton Carpenter, the brothers were able to use their unique foundry experiences to solve the problem of the day: a reliable sand source. They got their foot in the door by selling natural bonded molding sand, which was mined by hand, loaded into horse-drawn carts, and then delivered to customers. Not only did they sell the sand, but their technical expertise was readily available for all customers, big or small, to help manufacture the best castings. After surviving The Great Depression, Carpenter Brothers, Inc. slowly increased the number of products it distributed and expanded its sales territory into what it is today.
Carpenter Brothers, Inc. has committed itself to its customer's success by providing exceptional service to go along with the superior products and equipment they supply. With multiple warehouses around the United States we can get you the products you need when you need them. Our logistics team can handle getting your order to you by truck, plane, or train. Our technical sales and engineering staff all have experience in the industry, so when you buy from Carpenter Brothers you gain access to all of our knowledge.
