Kopar er notaður sem grunnefni í tinhúðuðum koparrörum og tinhúðuðum kopartækjum, samkvæmt lið 4.3.1. Tinlag er sett á þetta undirstöðuefni með mismunandi aðferðum. Við flæði koparjóna inn í tinlagið myndast vaxandi melmilsfasi sem samanstendur af tini og kopar (-fasi = Cu 6 Sn 5 ).
- [en] For tinned copper tubes and tinned copper fittings as base material copper according to 4.3.1 is used. On this substrate material a tin layer is deposited by different processes. By diffusion of copper ions into the tin layer the formation of an increasing intermetallic phase consisting of tin and copper (-phase = Cu 6 Sn 5 ) is formed.

- [en] intermetallic compounds: Materials composed of two or more types of metal atoms, which exist as homogeneous, composite substances and differ discontinuously in structure from that of the constituent metals. They are also called, preferably, intermetallic phases. Their properties cannot be transformed continuously into those of their constituents by changes of composition alone, and they form distinct crystalline species separated by phase boundaries from their metallic components and mixed crystals of these components; it is generally not possible to establish formulas for intermetallic compounds on the sole basis of analytical data, so formulas are determined in conjunction with crystallographic structural information (McGraw-Hill Science and Technology Encylopedia)
