Cubond^® Brazing Paste

Description

Cubond® is a series of furnace-brazing copper-based paste formulations in proprietary vehicle suspension systems.

Furnace brazing is an economical joining method whereby most ferrous and certain non-ferrous metal components can be solidly joined together in a continuous belt furnace.

Cubond® copper brazing pastes are used worldwide as the “universal preform.” It is an economical and preferred alternative to pressed slugs, solid wire, and strip preforms, offering little to no handling or waste. The paste is precisely deposited to achieve excellent weight control and placement.

Cubond® pastes are designed to be dispensed by hand-held devices or by automatic dispensing equipment to the braze joint. The paste is retained in position during the furnace heating cycle. The vehicle evaporates; the filler metal melts, fills the joint area, and solidifies upon furnace cooling to form a strong leak-free brazed joint.

  High purity copper
