Product Description
China solder wire 40/60
Solder wire is widely used in electronic soldering and metal soldering etc, and there are so many types of solder wires. In the market, especially when we just buy small quantity for home use, you mind not pay attention what type of solder wire it is, as long as it functions normally for soldering purpose. But as professional working in the solder business, we're obliged to share more knowledge that we have about the solder wire for all clients and users.
What is China solder wire 40/60 referring to?
1. From the number 40/60, we can tell right away that this China solder wire is a tin lead alloy, as generally the tin lead solder wire will be marked with such format of number to show the ingredient. The common sense is that the first number 40 represents Sn40 which means the percentage of tin inside the China solder wire is 40%; while the second number 60 represents Pb60 which means the percentage of lead inside the China solder wire is 60%. So in solder business, you can see this China solder wire 40/60 also labelled as solder wire Sn40Pb60, they both mean the same alloy and composition.
2. But from this name we cannot tell if it's a flux cored China solder wire or a solid core solder wire. The difference is that if the China solder wire 40/60 comes with a rosin flux cored, during soldering you don't have to apply for external flux, but on contrast if using a solid core solder wire then you will need to apply external flux during soldering. Nowadays most China solder wire comes with a rosin flux core which is convenient and easy to use for most clients; only in special case, such as industrial application where the electronic manufacturers are using automatic robots to do soldering then they might prefer a solid core China solder wire 40/60. It's easy to differentiate whether it's flux core or not. First is in the circular label put on each solder coil, the manufacturer will mark if it's flux cored or not on the label. But in case you don't see such information on the label, then just observe the cut area of the solder wire, if it's rosin flux cored China solder wire, you will see a tiny white spot (the flux) inside the core.
The China solder wire 40/60 is with very reasonable cost and can meet most of the general soldering purpose. If you need to buy this type, contact us at Email: xfsolder@gmail.com or xfsolder@163.com , Whatsapp/Wechat: 008613450770997, main website: www.xfsolder.com
