Description

Lead, Antimonial is a metallic alloy primarily composed of lead with a significant proportion of antimony. This combination is valued for its enhanced mechanical properties, including greater hardness, tensile strength, and resistance to creep compared to pure lead. It is a critical material for industrial applications requiring durable, castable metal with specific electrical or chemical characteristics. Key industries that utilize this alloy include battery manufacturing, radiation shielding, and specialized casting.

Application

• Grid Alloy for Lead-Acid Batteries: The primary application is as the grid material in automotive and industrial battery plates, where antimony improves casting fluidity, mechanical strength, and deep discharge recovery.
• Radiation Shielding: Used in the production of shielding components for medical (X-ray) and nuclear applications, offering a superior balance of density and structural integrity.
• Solders and Fusible Alloys: Employed in specialized solders with specific melting points and in fusible plugs for safety devices.
• Ammunition and Shot: Serves as a hardening agent in lead shot and certain types of ammunition to improve ballistic properties.
• Bearing Metals and Bushings: Used in traditional Babbitt metal bearings for its anti-friction and load-bearing capabilities.
• Cable Sheathing: Provides a tough, corrosion-resistant protective covering for underground and submarine power cables.
• Chemical Industry Equipment: Fabricated into linings, pipes, and vessels that handle corrosive substances like sulfuric acid.
• Type Metal: Historically important in printing for producing sharp, durable typefaces that withstand repeated use.

Quality Control

Our Lead, Antimonial alloy is produced under strict process controls to ensure batch-to-batch consistency and compliance with industry specifications such as ASTM B29. Quality is verified through rigorous testing for critical parameters including antimony content, hardness (Brinell scale), tensile strength, and the presence of trace impurities like arsenic, tin, and copper. A comprehensive Certificate of Analysis (COA) detailing the chemical composition and physical properties is provided with each shipment to guarantee material suitability for your specific application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizers. Maintain ambient temperature (15-25°C). Isolate from food and foodstuffs. For long-term storage, ensure packaging integrity to prevent surface oxidation.
