Export-standard solder alloys forged in India. Trusted by defence, aerospace, and high-volume electronics manufacturing. Engineered for the world.
Tinmann Solders is India's premium solder brand — supplying wire, bar, ingot, paste and flux products sourced from ISO 9001:2015 certified manufacturing facilities. From leaded eutectic alloys for domestic production lines to high-purity SAC305 for critical aerospace assemblies, every product is BIS IS 1921 certified, batch-tested, and fully traceable.
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.
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.
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.
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.

The industry workhorse. Eutectic composition — lowest melting point at 183°C. Sharp solidification, excellent wettability, easy rework. Ideal for domestic electronics. Not cleared for RoHS-regulated export markets.
General-purpose tin-lead solder with a pasty range of 183–190°C. Preferred for through-hole, hand soldering and wave soldering in domestic non-export environments. Cost-effective with a forgiving process window.
Cost-optimised lead-free alloy for export markets. Low silver content keeps the price competitive while delivering reliable wettability and joint strength. RoHS ready without SAC305 silver pricing.
The gold standard for critical applications. High silver delivers superior creep resistance, thermal fatigue performance and mechanical strength. Specified by defence, aerospace and avionics OEMs globally. Premium price, zero compromise.
The perfect alloy. No lead, no silver — fully RoHS compliant and export-ready. Most cost-effective lead-free solution on the market. Ideal for wave soldering at scale where SAC alloys are cost-prohibitive.
SMT-grade solder pastes in Type 3, 4 and 5 powder sizes for reflow soldering. No-clean, water-soluble and halogen-free flux for wave, selective and hand soldering. IPC-J-STD-004B classified. Fine-pitch print performance.
Qualified by DRDO, HAL, BEL, ECIL, ISRO. SAC305 for mission-critical boards. Batch traceability on every order.
Thermal cycling resilience and superior creep resistance for avionics, satellite and UAV assemblies.
High-volume, high-yield soldering for PCB assembly lines — SMT reflow and wave soldering at scale.
Vibration-resistant joints for ECUs, ADAS sensors and EV battery management systems.
Specialist alloys for PV ribbon soldering and solar panel tabbing. Optimised for outdoor thermal cycling.
Reliable bonds for base station PCBs, power electronics and industrial control systems.
Tin anodes and bar stock for electroplating and tinning in food processing and industrial sectors.
High-reliability RoHS-compliant alloys for diagnostics, implantables and medical instruments.
Proprietary dross reduction chemistry for wave soldering baths. Significantly lowers solder dross generation — reducing material waste and increasing bath life. Critical cost advantage for high-volume wave lines.
Full zero-halogen, zero-halide product line across flux and paste formats. Compliant with IEC 61249-2-21 and JPCA-ES-01 standards. Designed for Japan, Korea and halogen-sensitive EU markets.
All flux and solder products formally classified under IPC-J-STD-004B and IPC-J-STD-006C. Enables OEM qualification in regulated industries without re-testing. Full documentation available.
Dedicated applications engineers for on-site audits, wave line optimisation, defect analysis, and alloy transition support. We don't just supply — we solve problems on the factory floor.
Every batch analysed using X-ray fluorescence and ICP-OES spectrometry. Bath impurity testing for wave solder pots available as a service — critical for maintaining joint quality over long runs.
Closed-loop solder reclamation for wave soldering dross. Recover and recycle spent solder material with a certified partner. Reduces hazardous waste liability and lowers net material cost.
100% domestically sourced from ISO 9001:2015 certified manufacturing facilities under export-grade quality systems. Every batch traceable from raw material procurement to finished product dispatch.
Every product is manufactured at BIS IS 1921 and ISO 9001:2015 certified facilities. IPC-J-STD, RoHS and halogen-free compliant — full CM/L traceability and certification documentation available on every order.
Wire, bar, ingot, paste and flux across leaded and lead-free formulations. Multiple gauges, custom reel sizes, and OEM packaging available on request.
XRF and ICP-OES verified. No lot-to-lot variation. Critical for automated SMT lines where inconsistent alloy chemistry causes process drift and yield loss.
Approved vendor for major Indian defence PSUs. Products meet MIL-spec and aerospace quality requirements. Full CoC, CoA, and material traceability documentation on request.
You can buy solder from any manufacturer directly. Here's why the ones who buy through Tinmann don't go back.
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 PackagingWe 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 RequalifyingEvery 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 DispatchTin 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 SurprisesThis 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 DevelopmentIf 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 AlwaysShare 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.
