Nickel-based
Nickel-based filler material is a brazing filler composed of nickel as the matrix, supplemented with low-melting-point elements (such as boron, silicon, phosphorus, etc.) and strengthening elements (such as chromium, cobalt, molybdenum, tungsten, iron, etc.)
Copper-based brazing alloy
Features:
Copper-based brazing alloys refer to a class of brazing filler materials whose primary base element is copper (Cu). Brazing is a joining process in which the filler metal—whose melting point is lower than that of the base materials (the workpieces being joined)—is heated until it melts. The molten filler then wets the base materials, fills the gaps at the joint, and, through mutual dissolution and diffusion with the base materials, forms a strong bond between the workpieces.
