Lampert Welding wire – Silver Ag 970 (1000 mm x 0.35 mm)

Description

High-Fineness Silver Welding Wire with Superior Flow and Ductility

This Ag 970 silver welding wire is designed for precision welding in jewellery production and repair, offering an enhanced flow and softness compared to standard sterling silver (Ag 925). With a fineness of 970, the wire contains a higher proportion of fine silver, which significantly improves ductility, workability, and weld behaviour under low-power welding conditions.

Supplied in a 1000mm length and 0.35mm diameter, this wire is ideal for use with PUK welding systems, where precise control of heat and material addition is essential. Despite the increased silver content, the wire is visually identical to sterling silver, ensuring a clean, seamless appearance in repairs or new construction.

Enhanced Performance for Clean and Reliable Joins

The higher fine silver content in this Ag 970 alloy improves flow characteristics, allowing the wire to move smoothly into joins without leaving excess residue or causing pits. This makes it ideal for filling pores, repairing cracks, retipping settings, or rebuilding worn areas on sterling silver pieces.

In addition to improved flow, the added ductility means the wire can be more easily manipulated, especially in close-proximity welds or intricate areas. It performs consistently under the low energy pulses used in PUK micro-welding, reducing the risk of overheating or discolouration.

Suitable for Repairs and Fabrication in Sterling Silver

Although Ag 970 contains more fine silver than traditional Ag 925, it maintains excellent colour compatibility, blending seamlessly with existing sterling silver components. This makes it an excellent choice for jewellers needing a clean finish without visible seams, especially in visible or high-polish areas.

The long wire length allows for efficient workshop use, giving jewellers the ability to cut and apply the exact amount needed with minimal waste.
