Antimony is a silvery, brittle metalloid widely used in industrial applications for its strength-enhancing, flame-retardant, and corrosion-resistant properties. Nuclead offers high-quality antimony for sale and antimony-lead alloy products for customers across various sectors, including manufacturing, chemical processing, electronics, ammunition, and metallurgy. Whether you need bulk antimony for casting applications or precise alloy formulations for specialized performance, our products are engineered to meet your exact requirements.
What Is Antimony?
Antimony (Sb), atomic number 51, is primarily used in alloy form to improve the hardness and durability of lead and other base metals. In its pure form or as antimony oxide, it is also a vital ingredient in flame retardants, semiconductors, and batteries. Nuclead supplies both elemental antimony and antimony alloys designed for performance in high-stress industrial environments.
We maintain rigorous quality control processes, ensuring that every shipment meets strict chemical and physical specifications. Our antimony is sourced and manufactured according to customer demand for purity, particle size, and form (ingots, powder, pellets, or rods).
Industrial Applications of Antimony
Ammunition and Ballistics
Antimony is a critical component in the production of hard lead alloys for bullets, shot, and other ammunition components. When alloyed with lead, antimony significantly increases hardness without compromising malleability, making it ideal for forming consistent, accurate projectiles.
Nuclead offers antimony alloys with custom ratios to fit specific ballistic requirements, ensuring superior performance, durability, and safety.
Battery Manufacturing
Lead-acid batteries rely on small amounts of antimony to strengthen lead grids and improve battery life. This application is vital for automotive, marine, and backup power systems. Antimony allows for stronger plates that resist deformation during charge and discharge cycles, enhancing overall performance.
We supply battery-grade antimony with consistent purity levels to ensure reliability and long service life in energy storage systems.
Flame Retardants
Antimony trioxide is widely used as a synergist with halogenated flame retardants in plastics, textiles, coatings, and electronic housings. It plays a crucial role in suppressing flames and reducing fire hazards in consumer electronics, automotive interiors, and construction materials.
Nuclead provides antimony compounds that meet global fire safety standards, ensuring compatibility with a wide range of polymer systems and commercial formulations.
Metallurgical Alloying
In foundries and casting operations, antimony is added to base metals like tin, copper, and lead to increase hardness and mechanical strength. It is used in bearings, type metals, and pipe alloys. It also improves corrosion resistance and casting properties.
Nuclead’s antimony alloys can be custom-blended to meet specific metallurgical properties, including thermal expansion, electrical conductivity, and wear resistance.
Glass and Ceramics
Antimony oxide is used as a fining agent in the production of glass, helping remove bubbles and improve clarity. It also acts as a catalyst in the manufacturing of PET plastics and certain ceramic glazes.
Our high-purity grades of antimony oxide are designed to maintain the optical and physical integrity of advanced materials.
Antimony Products Offered by Nuclead
Antimony Ingots
Ideal for alloying and large-scale applications, antimony ingots are cast in standardized shapes for easy handling, storage, and remelting. Nuclead provides ingots in multiple weight classes with purity levels typically ranging from 99.5% to 99.9%.
Antimony Powder
Used in pyrotechnics, chemical formulations, and flame retardants, antimony powder offers maximum surface area for fast reaction and dispersion. Particle size can be tailored to suit the process, from fine mesh to granulated form.
Antimony Pellets and Shots
These forms are ideal for precision alloying or metered feed into manufacturing systems. Pellets and shots provide uniform distribution during melting and are available in custom diameters and packaging options.
Antimony-Lead Alloys
We specialize in casting antimony-lead alloys in customizable ratios, such as 5%, 6%, 10%, or 12% antimony content. These alloys are commonly used in radiation shielding, lead-acid batteries, and ammunition.
All materials are manufactured and tested in accordance with industry specifications to guarantee mechanical performance and consistency.
