What is solder wire? Overview of solder wire to know

Tin solder is an indispensable material in the fields of mechanics, electronics, and electrical engineering. So do you know what solder wire is? Follow the article below to know the information related to this material!

What is solder wire?

Solder tin, also known as lead solder, is an alloy with a low melting point, about 90 – 450 degrees Celsius. Thanks to this property, solder tin is used to bond metal surfaces type together.

Called solder wire, leaded solder wire, but actually, the main ingredient to make up this material is an alloy consisting of Tin (Sn) and Lead (Pb). Some types also add Silver (Ag), Copper (Cu).

Often solder wire is applied with a soldering iron to create a strong solder joint. But still maintain the characteristics of the weld metal that is capable of conducting electricity, welding, and melting at low temperatures. This application of tin solder makes a great contribution to industry and repair.

Solder wire is divided into how many types?

Solder wire on the market today is divided into two types: leaded solder and lead-free solder.

Leaded solder wire

Solder wire with leaded is a type of solder made up mainly of 2 metals, Tin (Sn) and Lead (Pb). Currently, leaded solder wire is popular in 2 types as follows:

63/37 solder with 63% Tin and 37% Lead: This is the standard solder for shiny, fusible solder. Leaded solder wire ratio creates a Eutectic alloy with a melting point of 183 degrees Celsius, commonly used in electric welding techniques.

Type 60/40 solder with 60% Tin and 40% Lead: This type is less used than type 63/37 because it gives poorer solder quality, requires a higher melting temperature, and the solder joint is not as shiny as the solder type. 63/37.

Lead-free solder wire

Lead-free solder wire is mainly composed of a mixture of metals such as Tin (Sn), Silver (Ag), and Copper (Cu) with a ratio of 96.5%Sn, 3% Ag, and 0.5%Cu. Compared to standard solder tin with a ratio of 63/37, this is much better. It gives good electrical conductivity and is less prone to deformation. At the same time, the tensile strength is also better.

In addition, there is a type of solder that is made from 100% pure tin with a melting point of 340 degrees Celsius to 370 degrees Celsius. This is an extremely safe solder for users. However, with such a high melting temperature, it is more difficult to weld, and fluxes are needed to achieve the desired weld quality.

Is solder wire toxic?

Lead is a toxic substance to the body, so solder wire containing lead is harmful to users.

Just a small amount of lead falling into the body will be dangerous to many organs and tissues such as the heart, bones, lungs, and intestines, … And the symptoms you will experience when the body is contaminated with lead are headaches, anemia, discomfort in the body,… If more severe, it can cause coma and death.

Therefore, leaded solder is not used in plumbing. Mainly used only in the electrical industry and the welder must wear protective measures to avoid harm to the body.

Today’s trend, people often use lead-free solder wire. Because it is safe for the health of the user and still gives the required weld.
