Introduction
C. Hafner & Hilderbrand SA is a Swiss company with over 50 years of expertise in precious metal brazing and soldering pastes for the jewellery, watchmaking, and industrial sectors. Based in Plan-les-Ouates, Switzerland — the heart of the global watchmaking and jewellery industry — Hilderbrand has built a reputation for producing the most reliably formulated brazing alloys available to the trade.
Their products are trusted by the world’s most demanding jewellery manufacturers and goldsmiths because the quality of a solder joint is never negotiable in fine jewellery — it either holds perfectly or it doesn’t. Hilderbrand’s formulations are built around that reality.
NJTPL has been supplying Hilderbrand products to Indian jewellery manufacturers, workshops, and goldsmiths since 2002 — offering genuine product access, technical guidance, and local support from Mumbai.

Why Brazing Paste Matters in Jewellery Manufacturing
In jewellery making, the way two metal parts are joined is as important as the design itself. Traditional soldering with wire or sheet solder requires skill, generates waste, and can result in uneven flow, flux contamination, or colour mismatch — particularly on multi-component pieces assembled in stages.
Brazing paste solves these problems. Pre-mixed with flux and dispensed in precise quantities, Hilderbrand pastes eliminate the need for separate flux application, allow accurate positioning before heat is applied, reduce material waste significantly, enable up to 4x faster soldering on production benches, and produce cleaner, stronger joints with less post-process clean-up.
For Indian jewellery manufacturers working with 22ct, 18ct, 14ct, and 9ct gold — as well as platinum — Hilderbrand offers colour-matched alloys that preserve the integrity and hallmark compliance of the finished piece.
Product Range
Carat Gold Brazing & Joining Solutions
Hilderbrand’s carat gold brazing alloys are the core of their product range — precision-formulated paste solders for joining gold jewellery across all standard carats. Each alloy is colour-matched to its parent metal and formulated at or above the required precious metal content for hallmarking compliance. CF grades include an integrated H-flux binder — no separate flux application required. CNF grades are formulated without nickel or fluoride, the correct choice for manufacturers supplying EU markets or producing skin-contact jewellery under EU nickel restrictions. Available for 22ct, 21ct, 18ct, 14ct, and 9ct gold in yellow, white, and pink colour variants.
Platinum Brazing Alloys
Hilderbrand’s platinum brazing alloys are formulated specifically for joining platinum jewellery — a technically demanding application where working temperature, alloy composition, and joint precision are all critical. The range covers standard 950Pt alloys used in Indian jewellery manufacturing, with grades suited to torch, laser, and resistance welding applications. Correctly applied with a small syringe tip to the joint area only, Hilderbrand platinum pastes produce clean, strong joints with minimal post-joining clean-up on finished platinum pieces.
Precious Metal Powders
Hilderbrand produces gas-atomised precious metal powders — gold and palladium alloy powders qualified for selective laser melting (SLM) applications. These powders are the compatible consumable for the SISMA MySint 100 metal 3D printing machine. For manufacturers running additive manufacturing operations, Hilderbrand powders deliver the alloy consistency, particle size distribution, and flowability that SLM processes require for reliable, repeatable 3D metal printing results. NJTPL can advise on the correct powder grade for your specific alloy and MySint 100 configuration.
Syringes & Cartridges
Hilderbrand’s MK3 syringe dispenser system is the recommended application method for all Hilderbrand brazing pastes — giving the operator precise, controlled paste delivery directly to the joint area. The syringe system significantly reduces paste waste compared to spatula application, improves joint consistency by controlling the amount of paste applied, and is far more practical on production benches processing multiple joints per piece. Snap-tight end caps keep partially used syringes airtight between shifts, extending paste shelf life. NJTPL supplies both the pastes and the dispensing accessories together.
Why Indian Jewellers Choose Hilderbrand Through NJTPL
No flux required — paste has it built in
Every Hilderbrand CF paste contains an integrated H-flux binder. Apply, heat, and the joint flows cleanly — no separate flux step, no risk of under-fluxing.
Colour match on the finished piece
Each alloy is formulated to match the carat and colour of the parent metal. A correctly soldered joint should be invisible under normal finishing.
Hallmark compliance maintained
All carat gold alloys are formulated at or above the required precious metal content — your 18ct piece remains 18ct after joining.
Compatible with torch, laser, and resistance soldering
Hilderbrand pastes work with all common joining methods used in Indian workshops.

Frequently Asked Questions
What is the difference between CF and CNF grades?
CF grades contain integrated flux and may include nickel or palladium. CNF grades contain no fluoride and no nickel — the correct choice for EU export manufacturers or skin-contact jewellery under EU Directive 94/27/EC.
Does Hilderbrand produce alloys for 22ct gold?
Yes. The CF 22KYES and CF 21KYS are formulated for the dominant Indian carats. NJTPL can advise on working temperatures and torch settings for both grades.
What Hilderbrand powders are compatible with the SISMA MySint 100?
Hilderbrand gas-atomised gold and palladium alloy powders are qualified for SLM applications including the MySint 100. NJTPL can advise on the correct grade for your alloy requirements.
