Leaded Alloys — Non-RoHS

Traditional Sn-Pb alloys (63/37, 60/40) for domestic electronics. Unmatched wettability, well-understood joint behaviour, lower process temperatures. Best for Indian market where RoHS is not mandated.

Lead-Free Alloys — RoHS Compliant

SAC and Sn-Cu alloys meeting EU RoHS Directive 2011/65/EU and IPC-J-STD-006. Mandatory for export to Europe, North America, Japan. Available in wire, bar, ingot and paste formats.

Solder Paste & Flux

SMT-grade solder pastes (Type 3, 4, 5 powder) for reflow. No-clean, water-soluble and halogen-free flux variants. Consistent slump resistance, fine-pitch printing, optimal voiding performance.

Technical Support

On-site process support, dross analysis, alloy consultation, and custom formulation available. Our engineers work with your production line to maximise yield and minimise waste.

WHY BUY
THROUGH US

You can buy solder from any manufacturer directly. Here's why the ones who buy through Tinmann don't go back.

01 — Specification Control
You Tell Us What You Need.
We Build It.

Direct manufacturers make what they make. We exist between the market and the mill — which means your alloy spec, flux activity, resin content, wire gauge, and packaging are all dictated by your process, not by what a factory has in stock. If your line needs something no one shelves, we source or formulate it.

↳ Custom Alloy · Custom Format · Custom Packaging
02 — Multi-Tier Supply
Economy. Standard. Premium.
All BIS. All ISO. One Supplier.

We work with multiple BIS IS 1921 certified, ISO 9001:2015 manufacturing partners. That means we can offer you an economy-grade solder for your high-volume wave lines and a premium-grade alloy for your critical SMT assemblies — under a single order, single invoice, single point of accountability. No other solder company gives you that flexibility.

↳ All Grades Certified · Switch Without Requalifying
03 — Batch Traceability
The Batch You Receive
Is the Batch You Ship.

Every coil, bar, and cartridge is tagged with the manufacturer's lot number, our inward batch code, and the BIS CM/L reference — cross-linked and logged in our system. What lands in your goods-in matches exactly what goes out to your customer. Full CoA, CoC, and batch records available on demand. No mixing, no substitution, no ambiguity.

↳ Lot-Locked · CM/L Referenced · CoA on Every Dispatch
04 — Market Intelligence
Monthly Price Briefings.
You Never Overpay.

Tin and lead prices move. We track them so you don't have to. Every month we send you a benchmarked price comparison across supplier grades — showing you what the same alloy costs elsewhere and what we're charging. Transparent, documented, actionable. You walk into every purchase decision with full market visibility.

↳ Monthly Market Reports · Benchmark Comparisons · No Surprises
05 — The Closed Loop
We Don't Just Supply You.
We Bring You Clients.

This is our most asymmetric advantage. We have deep visibility across Indian electronics manufacturing — PCB assemblers, EMS houses, OEMs. If you are trying to crack a customer, tell us. We will give you their procurement contact, their current supplier, their likely switching price, and the right Tinmann product to lead with. You close the order. We supply the solder. Everyone wins.

↳ Client Intelligence · Warm Introductions · Joint Account Development
06 — Certified. Regardless.
Switch Manufacturers.
Never Switch Certifications.

If a manufacturing partner changes or we upgrade your grade, your product certification doesn't reset. Every supplier in our network carries BIS IS 1921 and ISO 9001:2015. Your TDS, your CoA, and your compliance documentation remain consistent across every order. Your quality systems never have to explain a supplier change.

↳ Continuous BIS Coverage · ISO Chain Maintained · Audit-Ready Always

TELL US THE CLIENT
YOU'RE TRYING TO CRACK.

Share a target account. We'll identify the right product, the right price point, and make the introduction. The loop closes when you win the order.
