Use
Since an inert oxide film has formed on the aluminum surface, it can only be brazed with solder alloys containing aluminum. Considering that brazing is mainly used for tinning cable sheaths and cable connections, the following solder grades have found practical application:
| Solder grade | Application |
| 34-A and 35-A | Solder joints subjected to high mechanical stress |
| A and B | Surface tinning of aluminum casings and cables. |
| P250A | Brushing copper lugs when connecting them to aluminum cables. |
| P300A | Copper lugs tinning, soldering of underground aluminum cables. |
| P300B | Soldering by pouring, when copper cores are connected to aluminum ones. |
| TSO-12, TSA-15. | Analogous to P300B when soldering individual cores of aluminum and copper wires. |
Cadmium: Due to the toxicity of cadmium is rarely used, mainly for wires with small cross-sections. Supplier Evek GmbH offers to buy aluminum solder at an affordable price in a wide range. We provide product delivery anywhere in the continent. The price is optimum.
