Our laboratory is an expert in metallurgy and alloy analysis, particularly tin, and offers its expertise to analyze the chemical composition and control of metal alloy grades.
Your need: carry out an analysis of a tin alloy
Tin is a relatively rare precious metal that occurs in the form of an ore: cassiterite. This silver-grey metal is one of the ingredients of bronze. It resists corrosion through the formation of a protective oxide layer. Tin and its alloys are used by the food industry and the electronics industry, in silversmithing, and for decorative objects.
The different types of tin and alloys
Here are the main tin-based alloys, widely used in industry for their mechanical and anti-corrosion properties or their solderability:
Analysis of tin composition: an essential quality control measure
Analysis of tin’s chemical composition makes it possible to verify the presence and concentration of essential alloying elements, such as lead, copper or silver, thereby ensuring that materials comply with requirements for safety- and performance-critical applications.

FAQ
Tin has a low melting point (232 °C), good conductivity, and is chemically unreactive, making it an excellent component for solder alloys, corrosion-resistant coatings, and decorative alloys.
Yes, tin is highly recyclable, particularly from electronic waste, used solder, or cans (tinplate).
ISO 9453: designation of soft solder alloys
J-STD-006: classification of electronic solders
RoHS / REACH: restrictions on the use of lead and other heavy metals
Because it has a low melting point, good wettability, low oxidation, and forms stable alloys with many metals.
Tin-lead solder (SnPb) melts at a lower temperature (183 °C) but contains lead (toxic), whereas SAC solder (tin + silver + copper) is lead-free, slightly more brittle, and has been used since RoHS.
