Lead Free Solder Wire:Eco-Friendly and Residue-Free

Kothari Metsol is a leading manufacturer of lead free solder wire. We are dedicated to addressing the issue of pollution caused by lead poisoning by offering a range of environmentally friendly soldering solutions. Our lead free solder wire is specifically designed to replace conventional lead solders while ensuring compliance with ROHS standards.

Our lead free solder wire is available in two forms: Flux core and Solid Solder Wire. Both options provide excellent soldering performance without the harmful effects of lead. By choosing our lead-free solder wire, you can contribute to a safer and healthier working environment.

Thanks to our advanced manufacturing techniques and strict quality control, we ensure that our lead free solder wire meets the highest standards of purity and reliability. Whether you are in electronics, electrical, automotive, or other industries, our solder wire provides consistent and durable solder joints for all your applications.

Lead free solder wire and lead wire for soldering are essential in various industries, especially where environmental and health safety standards are critical. These materials are commonly used in the electronics industry for assembling circuit boards, ensuring devices meet RoHS (Restriction of Hazardous Substances) compliance by eliminating harmful lead content. Lead wire for soldering has traditionally been used for these applications, but the shift to lead free solder wire helps reduce the environmental impact.

In automotive applications, lead free solder wire provides strong, reliable joints in electrical systems, contributing to vehicle durability and performance. The aerospace and medical device industries also depend on lead wire for soldering for critical applications, where both safety and performance are non-negotiable.

Additionally, lead free solder is widely used in plumbing and construction for its corrosion-resistant properties, making it ideal for environmentally friendly and sustainable projects. The transition from lead wire for soldering to lead free options underscores a commitment to safer, eco-conscious manufacturing processes without compromising quality or reliability.

We follow a refined and efficient manufacturing process that ensures we deliver only the highest quality lead free wires. As a leading supplier for lead wire for soldering, we focus on innovation, precision, and sustainability in every step of production. Here’s how we achieve excellence:

Raw Material Selection for Lead Free Solder Wire: At Kothari Metsol, the process starts with selecting high-quality raw materials. Instead of using lead wire for soldering, we use eco-friendly, lead-free materials like tin, copper, and other alloys to create lead free solder wire. This ensures the final product is free from toxic lead content, making it safer for both users and the environment.

Alloy Formation and Melting:The chosen materials are carefully melted and blended to create a homogeneous alloy. For lead free solder wire, a common composition is tin combined with other metals like copper (Sn-Cu) or silver (Sn-Ag), which enhances performance and ensures compliance with environmental standards. This process replaces traditional lead wire for soldering with a safer, more sustainable solution

Wire Drawing Process: After forming the alloy, the next step is the wire drawing process. The molten solder alloy is drawn through a series of progressively smaller dies, reducing the diameter of the wire to the desired thickness. Lead free solder wire is drawn into various sizes, from 10 SWG to 22 SWG, to cater to different soldering applications in industries like electronics, automotive, and plumbing.

Flux Core Insertion (for Flux-Cored Lead Free Solder Wire):In addition to solid solder wire, we also offer flux-cored lead free solder wire. During this process, flux material is inserted into the hollow core of the solder wire. The flux helps improve solder flow, ensuring smooth, clean joints without the harmful effects of lead. This lead free solder wire is ideal for applications where precision and clean connections are essential, such as in the electronics and medical device industries.

Annealing for Flexibility:The lead free solder wire undergoes an annealing process where it is heated to a specific temperature in a controlled environment. This step softens the wire, making it more flexible and easier to handle during soldering. Annealing ensures that the wire retains its strength while being pliable enough for various soldering tasks.

Coating for Corrosion Resistance:Some lead free solder wires may be coated for added protection against corrosion. This ensures that the solder wire maintains its performance over time, especially in harsh environments like automotive or plumbing applications. The coating helps prevent oxidation, ensuring a longer shelf life and more reliable solder joints.

Spooling and Packaging:After the wire is drawn, annealed, and coated (if applicable), it is carefully wound onto spools. These spools are then packaged to protect the wire from moisture, which can cause oxidation. We ensure that each spool of lead free solder wire is packaged in a way that maintains its quality during storage and shipping.

Rigorous Quality Control and Testing:We apply stringent quality control measures throughout the manufacturing process. Every batch of lead free solder wire undergoes extensive testing to check for factors such as melting point, flow characteristics, and consistency. These tests ensure that our lead free solder wire provides reliable, consistent performance across a range of industries, including electronics, automotive, and electrical applications.

Final Inspection and Delivery:Before shipping, all spools of lead free solder wire are inspected one final time to ensure they meet our high standards. We carefully check for uniformity in diameter, flux distribution, and overall quality. Once approved, the lead free solder wire is ready for delivery, ensuring that customers receive a top-quality, eco-friendly soldering solution.
