Things That You Should Know About Soldering Alloys

Brazing is a process that creates a thermally and electrically conductive connection between two components of the electronics. 

A metal or a metal alloy is used to melt the two surfaces together to create this connection. However, any metal or alloy can not be used for brazing – there are certain desirable properties that are required. You can also buy materials like nickel alloys from companies such as https://rjtechnical.com/ for extreme work environments.

These properties ensure that the welding process is safe and a good connection is made at the end. Here are some important things you need to know about welding alloys.

Until a few years ago, the solder alloy most commonly used was the eutectic alloy lead tin with a melting point of about 188 ° C. This particular combination of brazing alloys gave place high performance and lower defects. 

Apart from the joint training of tin whiskers, the only other problem with this combination of alloy was the presence of lead that government legislation is forcing the electronics industry to consider the use of alloys without lead up lead alloys for many applications.

In recent years, due to increasing environmental concerns, there have been new developments of alloys of lead free solder. 

Typically made of metals such as bismuth, indium and tin, lead-free alloys melt at low temperatures, making a range of new applications in the electronics industry. 

There is also less energy consumption during the welding process using these alloys, resulting in additional savings. 

The indium alloy is responsible for a large part of the durability and conductivity in the connection, while the bismuth is responsible for the reduction in melting points.
