Material components of electric soldering iron tip
First of all, the soldering iron head is not composed of a single metal, it is composed of copper, iron, tweezers, chrome, tin, and five brothers.
boss is copper
Copper acts as a heat conductor and is the main component of the soldering iron tip. It accounts for about 85% of the material of the soldering iron tip. Copper has good thermal conductivity, which is conducive to the rapid heating of the soldering iron tip. Good soldering iron tips are made of copper, but some manufacturers use brass. In order to reduce costs, it also reduces the soldering iron temperature. thermal conductivity of the head.
dick iron
Iron mainly plays an anti-corrosion role in the soldering iron tip, and is a key factor affecting the service life of the soldering iron tip. A good soldering iron tip has a fine and dense iron coating crystal structure and good corrosion resistance. Such a soldering iron tip has a long service life and a good tinning effect. Manufacturers with poor iron plating technology mainly rely on the thickness of the iron plating layer to control the service life of the soldering iron tip. Usually, if the iron plating layer is thick, the soldering iron tip will not be tinned, and if it is thin, it will not be durable.
old three nickel
The function of the tweezers on the tip of the iron is to prevent rust on the iron layer, and it is convenient for chrome plating later.
old four chrome
Chromium does not stick to tin, which prevents tin from running onto the handle of the soldering iron tip during use. Generally, the chrome plating time of the soldering iron tip is more than 5 minutes, and the ordinary decorative chrome plating is about 1 minute.
old five tin
The tin is on the head, and it is the part where the tin is stuck in use.
If you want to form a qualified and up-to-standard soldering iron tip, the five brothers are indispensable.
