There is extensive use of traditional tin-lead solders in the electronics world because of their performance, low melting point, and lower price. However, the growing awareness of environmental protection; the toxic action of lead has concerned much attention. Therefore, the Best Lead-free solder is available for electronics that need to meet health and environmental requirements.
Best Lead-Free Solder Wire For Soldering
Japan, the EU, the USA, and other countries of the world enforced the law to use the lead in electronic equipment, promoting lead-free soldiers. Hence in response, tin-silver, tin-copper, tin-bismuth, tin-antimony, tin-indium, and tin-zinc became the best replacement tin-lead solders.
Melting Temperature & Benefits Of Lead-Free Solder
Lead-free solders have a high melting point than tin-lead solders; however, tin-cu alloy has more potential for further development. Tin-copper alloys are comparatively in-expensive, have low melting point than all lead-free alloy solders.
| Solder Wire | Composition | Melting Temperature |
|---|---|---|
| Lead-Based Solder Wire | Lead (Pb) & Tin(Sn) | 183°C/361°F |
| Lead-Free Solder Wire | Tin (Sn) & Copper (Cu) | 217°C/422°F |
All though lead-free solder wire has a high melting temperature but here are some benefits of lead-free solders.
- High Joints Strengths
- Lead-free fumes
- Better fatigue Resistance
- Environment friendly
- Higher Temperature life.
- Harder soldering joints
We have collected some of the lead-free solder wires to help you buy, so here is the list of the top 10 lead-free solder wires.
