Pure tin Sn 95 / Sb 4 / Cu 1 lead-free (also for products that come into contact with food) with high-grade micro-purified tin in its purest form with very good flow properties compared to other lead-free alloys. This tin alloy with copper and antimony fulfils the highest requirements and was developed in cooperation with a professional foundry for casting miniatures and models. Thanks to the addition of antimony and copper, this alloy achieves a higher degree of hardness compared to pure tin.
Tin (Sn) The metal tin has been known since at least 3500 BC. Tin is used in a variety of ways as a component of alloys, alloyed with copper to form bronze or other materials. Nordic gold, the alloy of the gold-coloured euro coins, contains 1% tin, among other things.
Tin is called "stannum" in Latin, which is where the chemical symbol "Sn" comes from. Tin has a very low melting point of approx. 230 degrees Celsius.
Antimony (Sb) Antimony is used in alloys to harden lead and tin alloys. In contrast to all other metals, it expands when the molten metal cools (due to transformation into another modification): The antimony content can be adjusted so that such alloys do not shrink or even expand slightly during cooling; in the case of parts produced in casting moulds, the metal is pressed into all corners and angles during solidification, 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).
