Applications of Tin Lead Solder Wire 45/55

For Electronic & Electrical Assemblies & general purpose soldering either by hand solder or feed soldering. Besides for electrical industrial, this alloy can be made into 1.6mm or 3.2mm wire diameter to be used for soldering of plumbings, to join the gap between copper pipes and the fittings. But do not use it for drinking water pipe because this solder contains lead.

Packing of Tin Lead Solder Wire 45/55:

1. The 45/55 solder wire (Sn45Pb55) is available in many wire diameter & with different sizes of spools. We have ranging from 100g/spool, 200g/spool to 500g/spool or even 1000g/spool for client's option. Generally for repair shops or home use, small sized spool is more suitable, while for factory manufacturing purpose big spool is better.

2. Small size spool is generally packed at 20pcs/box (such as 100g/spool, 200g/spool). Big size spool is generally packed at 10pcs/box (such as 500g/spool, 1000g/spool).

3. Boxes will eventually be put into cartons making it better protected from damage during transportation.

4. We have plastic pallets to load the boxes, suitable for folk-lift operation and make it easier for shipping. 

5. If you need us to print your own private labels for the reels, we can manage for you with additional cost.
