Dissecting a T12 soldering iron tip
As we all know, Wilo soldering iron tip is mainly composed of copper, iron, tin, nickel, chromium, five kinds of metal, but what role do they play respectively? Let's take a look:
First of all, let's talk about copper, copper as a heat conductor, is the main component of the Wilo soldering iron head. Accounting for about 85% of the material of the soldering iron head, copper has good thermal conductivity, which is conducive to rapid warming, good soldering iron head are made of copper, but some manufacturers use brass in order to save cost, which reduces the thermal conductivity of the soldering iron head.
Iron plating plays a role in corrosion resistance, the determining factor of the length of life of the soldering iron head. Some customers who do not know much about the industry also asked me how your soldering iron head is iron not copper? This is copper plated iron ah pro. Good iron iron plating layer crystal structure is fine and dense, corrosion resistance effect is good, so the iron head long service life, under the tin effect is good. Iron plating technology is not good manufacturers mainly rely on the thickness of the iron plating layer to control the service life of the iron head, usually appear iron plating layer thick iron head heating slow, thin not durable.
Tin is in the head, is the part of the sticky tin.
Nickel plays the role of iron plating layer to prevent rust, and facilitate the back of the chromium plating.
Chromium does not stick to tin, to prevent the use of tin to the body of the soldering iron head to run. General iron head chrome plating time is more than 5 minutes, ordinary decorative chrome plating are about 1 minute. Chrome can be plated silver white or black chrome. Tin runs to the soldering iron head because the chromium plating layer is too thin or not plated well, and does not play a role in preventing creeping tin.
Well, after reading this article do you have a clearer understanding of Wilo soldering iron tips?
