Alloy Temperature Chart
The alloy temperature charts provide the melting point of various alloys available from Electroloy. This is to provide a reference for alloy selection for Lead free as well as special application whereby temperature is critical for a successful soldering solution.
Electroloy’s alloy code correspond with the alloy composition. Please make reference to the alloy code when making enquires or during ordering process.
