Product surface description: Smooth surface

The C72900 copper-nickel-tin plate has excellent welding properties and can be processed using various welding methods, such as argon arc welding, resistance welding and brazing.

Welding characteristics

The C72900 copper-nickel-tin plate exhibits excellent formability and crack resistance during the welding process, and the strength of the weld area is comparable to that of the base material. When using argon arc welding, by properly controlling the heat input, overheating and deformation can be avoided, making it suitable for welding requirements of complex structural components.

Applicable scenarios

The C72900 copper-nickel-tin plate is suitable for welding processing of electronic components (such as connectors), ship parts (such as propellers, valves), and aerospace structural components. It is particularly suitable for scenarios that require both strength and corrosion resistance.
