Pure tin Sn 95 / Sb 4 / Cu 1 lead-free (also for food contact products) with high-grade micro-purified tin in its purest state with very good flow properties compared to other lead-free alloys. This tin alloy with copper and antimony meets the highest requirements and was developed in cooperation with a professional foundry for the casting of miniatures and models. By adding antimony and copper, this alloy achieves a higher degree of hardness compared to pure tin.
Tin (Sn) The metal tin has been known since 3500 BC at the latest. As a component of the alloy, tin is used in many ways, alloyed with copper to bronze or other materials. Nordic gold, the alloy of the gold-coloured euro coins, contains, among other things, 1 % tin.
In Latin, tin is called "stannum", which is also where the chemical symbol "Sn" comes from. Tin has a very low melting point of about 230 degrees Celsius.
Antimony (Sb) Antimony is used in alloys to harden lead and tin alloys. Unlike all other metals, it expands when the melt cools (as a result of conversion to another modification): The content of antimony can be adjusted so that such alloys do not shrink or even expand somewhat when cooling. In the case of parts produced in casting moulds, this causes the metal to press into all nooks and crannies when solidifying, so that even complicated shapes and highly patterned surfaces can be produced without blowholes.
Copper (Cu) Copper is also a component of many alloys such as brass (with zinc), bronze (with tin) and nickel silver (with zinc and nickel).
