Composition and Characteristics of Spherical Copper-Based Alloy Brazing Powder

What Is It Made Of?

Spherical copper-based alloy brazing powders are primarily composed of koppar and other alloying elements like fosfor, silver, zink, och nickel. These additional elements enhance specific properties, such as wettability, corrosion resistance, or melting temperature.

Element	Typisk sammansättning (%)	Role/Function
Koppar (Cu)	50–95	Base material, provides strength and electrical conductivity.
Fosfor (P)	5–15	Improves self-fluxing properties and lowers melting point.
Silver (Ag)	0–40	Enhances flowability, reduces melting temperature, and improves joint strength.
Nickel (Ni)	0–20	Adds corrosion resistance and strength when brazing high-temperature alloys.
Zink (Zn)	0–10	Lowers melting point and improves wetting of the brazing alloy.
Others (e.g., Tin, Manganese)	≤ 5	Fine-tunes mechanical and thermal properties for specific applications.

Viktiga egenskaper

What sets spherical copper-based brazing powders apart from traditional powders is their spherical particle morphology. This shape is achieved using advanced atomization techniques, such as gasatomisering. Here’s why it matters:

Flytbarhet: The spherical shape ensures excellent flow, even in complex geometries, making it ideal for intricate joints.
Uniform Distribution: The powder spreads evenly, ensuring consistent bonding across the joint area.
Hög renhet: Minimal impurities ensure strong, defect-free joints.
Termisk konduktivitet: Copper provides excellent heat transfer, making it great for thermal management systems.
Korrosion Motstånd: Alloying elements like nickel and silver improve resistance against oxidation and chemical attacks.
