Aplikace

The balanced material properties of copper C17510 powder make it well suited for the following applications:

Pájení

Copper C17510 is used in making brazing pastes and preformed shapes due to its low brazing temperature, excellent flow and gap fill capabilities.

Typical brazes include:

• Copper, brass, bronze
• Steels, stainless steels
• Slitiny niklu
• Karbid wolframu

It is widely used to join components in:

• Výměníky tepla
• Oil coolers
• Electronic devices
• Řezné nástroje

Benefits for brazing:

• Excellent flowability and wetting
• Good gap bridging ability
• Uniform joint interfaces
• High joint strength
• Does not require flux with proper joint preparation

Tepelný management

C17510 finds use in thermal management applications thanks to its high thermal conductivity coupled with good strength:

• Chladiče
• Heat spreaders
• Thermal interface materials (TIMs)

It enables excellent heat dissipation in electronics cooling and thermal transfer processes. Can be integrated as Cu-C17510 coatings, structures or composites on device surfaces or heat sinks.

Benefits for thermal management:

• Greater ability to transfer heat than aluminum or copper alone
• Well-bonded metallurgical coatings for improved efficiency
• Withstands thermal cycling without degradation
• Ease of forming complex shapes

Elektrické kontakty

The alloy is applied in electrical components like:

• Connectors
• Relays
• Switches

It provides high electrical conductivity to allow signals and currents to pass through while having good strength, hardness and wear resistance to withstand repetitive contact forces over time.

Benefits for electrical contacts:

• Excellent electrical conductivity minimizes power losses
• Resists welding, arcing, and sticking of contacts
• Maintains surface smoothness and low contact resistance after prolonged use
• Tolerates occasional arcs without significant erosion

Protective Coatings

Copper C17510 coatings provide good wear protection in:

• Ložiska
• Bushings
• High pressure valves
• Součásti podvozku

The coatings act sacrificially under impact, abrasion, or chemical attack preventing wear on critical substrate surfaces.

Benefits as protective coatings

• Harder than regular copper providing wear resistance
• Withstands repetitive contact and impact
• Chemically compatible with ferrous alloys
• Retards galling and adhesive wear failure modes
• Restores dimensions of worn components
