Brazing Wires for Diamond Segments

All diamond tool segments adopt brazing process instead of common electric welding. XINXIN WELDING provides

complete brazing wire solutions for all kinds of diamond tools.

1. Silver brazing wires for stone saw blades and drill bits

Silver copper zinc brazing rods match high-frequency welding equipment.

▶ HL302 (15Ag) & HL303 (25Ag): Cost-effective choice for granite saw blades and ordinary core drill bits.

▶ HL304 (45Ag): Low welding temperature, prevents thin cutter heads and thin-wall drills from cracking.

▶ HL321 (49Ag): High toughness weld seam, suitable for dry cutting road saws and heavy wall saws to avoid cutter

head falling off.

HS221 brass wire is low-cost for light-load wet grinding discs. Its high welding temperature may damage diamond

cutter heads, so it cannot be used for dry cutting.

2. Active brazing wires for PCD diamond tools

Ordinary silver brazing wires cannot bond with PCD materials. We supply two titanium-containing brazing materials

for vacuum brazing:

▶ AgCuTi brazing wire: High bonding strength for high-end PCD turning tools, avoiding diamond graphitization.

▶ CuSnTi brazing wire: Lower cost, applied to oil drill bits and large grinding plates.

Important Welding Tips from XINXIN WELDING

▶ Silver brazing flux must be used in high-frequency brazing to remove oxide layers.

▶ Carbon steel and stainless steel welding rods are forbidden, as ultra-high temperature will damage diamonds.

▶ XINXIN WELDING silver brazing materials have wire, sheet and ring types, applicable to automatic and manual

welding machines.
