What are the different specifications for tin ingots?

Tin Ingot Specifications

Tin ingots are primarily produced in high-purity forms (99.90% to 99.99% Sn) with strict compositional controls. Key specifications include:

A. Chemical Composition (Typical Pure Tin Ingots)

Element	Sn 99.90% Max Impurity	Sn 99.95% Max Impurity	Sn 99.99% (Special High Grade)
Tin (Sn)	99.90% min	99.95% min	99.99% min
Lead (Pb)	0.08% max	0.02% max	0.005% max (Critical for food/solder)
Antimony (Sb)	0.02% max	0.01% max	0.002% max
Bismuth (Bi)	0.02% max	0.01% max	0.001% max (Avoids brittle phases)
Copper (Cu)	0.01% max	0.005% max	0.001% max
Iron (Fe)	0.01% max	0.005% max	0.001% max
Other Impurities (As, Zn, Ni, etc.)	0.03% max combined	0.02% max combined	0.005% max combined

B. Physical Forms & Dimensions

• Shape: Rectangular/square ingots (standard or custom sizes)
• Weight: Typically 25kg, 50kg, or 100kg per ingot (can vary)
• Surface: Smooth, minimal dross (oxide layer acceptable on top)

Common Grades:

• Sn 99.90% (Grade A) – General industrial use
• Sn 99.95% (Grade 1) – Electronics, soldering
• Sn 99.99% (Grade 2 / SHG) – High-purity applications (semiconductors, food packaging)
