Description

Tin CAS NO 7440-31-5 is a malleable, silvery-white post-transition metal with excellent corrosion resistance and low toxicity. It is a critical industrial material prized for its ability to form protective alloys and coatings. This versatile element is essential for manufacturers in the electronics, packaging, and metallurgical sectors seeking reliable, high-purity materials for soldering, plating, and alloy production.

Application

• Solder Alloys: A primary component in lead-free (Sn-Ag-Cu) and traditional tin-lead solders for electronics assembly and plumbing.
• Tinplate & Coatings: Electroplating or hot-dipping to create corrosion-resistant tinplate for food and beverage cans (tin cans) and protective coatings on other metals.
• Specialty Alloys: Key constituent in bronze (copper-tin), pewter, Babbitt metal (bearing alloys), and fusible alloys with low melting points.
• Chemical Synthesis & Catalysis: Used as a reducing agent in organic chemistry and as a component in catalysts for polyurethane and silicone production.
• Glass Manufacturing: Application in the production of float glass, where molten tin creates a perfectly flat surface.
• Energy Storage: Component in advanced battery technologies, including tin-based anodes for lithium-ion batteries.

Quality Control

Our Tin CAS NO 7440-31-5 is produced and handled under strict quality management protocols. We offer various grades, including high-purity (99.9% to 99.999%) for electronic applications and standard industrial grades. Quality is verified through assays and trace metal analysis via ICP-OES or similar techniques. Certificates of Analysis (COA) detailing purity and impurity profiles are provided with each shipment to ensure compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids and strong oxidizers. For long-term storage of fine powders, consider an inert atmosphere to minimize surface oxidation. Maintain ambient temperature conditions (15-25°C).
