Tin Alloying Element: Size Custom 1-50mm, Purity 99.95% Sn min

Q: What is the primary function of tin in copper-tin master alloys?

Tin enhances corrosion resistance, improves strength through solid solution strengthening, lowers melting point for better castability, and provides excellent bearing properties in final applications.

Q: Why is high purity important for tin alloying elements?

High purity ensures consistent alloy properties, prevents contamination from unwanted elements, enables precise composition control, and meets stringent industry standards for critical applications.

Q: What forms are available for industrial use?

Available as ingots (5-25kg), granules (1-10mm), pellets (3-15mm), and powder (50-500μm) to suit different melting equipment and process requirements.

Component Specifications

Definition

A specialized tin-based additive material designed for incorporation into high-purity copper-tin master alloys, where it serves as the primary tin source to achieve specific metallurgical properties. This element undergoes rigorous purification and processing to ensure minimal impurity content, enabling precise control over alloy composition, microstructure, and performance characteristics in final applications.

Working Principle

The tin alloying element dissolves into molten copper during the master alloy production process, forming intermetallic compounds and solid solutions that modify the base metal's properties. It lowers the melting point, improves fluidity, enhances corrosion resistance, and increases strength through solid solution strengthening and precipitation hardening mechanisms when properly heat-treated.

Materials

High-purity tin (Sn) with minimum 99.95% purity, typically containing controlled trace elements like lead (<0.01%), antimony (<0.005%), and copper (<0.001%) to meet specific alloy requirements. Available in various forms including ingots, granules, pellets, or powder with controlled particle size distribution.
