Vacuum brazing is widely applied in the tools and dies industry for manufacturing high-performance components such as cutting tools, grinding wheels, stamping dies, extrusion dies, and injection molds. It is especially valuable in the production of diamond tools, including diamond saw blades, grinding wheels, rollers, drill bits, engraving knives, beads, and grinding heads, used across woodworking, stone processing, glass cutting, and construction industries. These vacuum-brazed tools are crucial across sectors such as automotive, aerospace, electronics, metallurgy, geology, military, and infrastructure, where precision, strength, and durability are essential.
Oxygen-free copper is a high-purity copper material with extremely low oxygen content, usually less than 0.001%. Compared to regular electrolytic copper, oxygen-free copper offers higher electrical conductivity (above 101 % IACS), superior thermal conductivity (~390 W/m·K at 20 °C).
