Cu-W Sintered
Description
Cu-W Sintered is a copper-tungsten refractory alloy engineered for applications demanding high electrical conductivity paired with exceptional resistance to arc damage and non-welding behavior. It is produced via advanced powder metallurgy techniques to deliver uniform microstructure, durability and consistent performance across repetitive operations.
Key Features
- High Electrical Conductivity provides efficient current transfer in demanding electrical environments.
- Arc Resistance resists surface damage from electrical arcing, extending service life in high-stress contacts.
- Non-Welding Behavior minimizes material transfer and sticking under high current inter-ruptions.
- Robust Powder Metallurgy Structure yields fine-grained, reliable performance in heavy-duty applications.
Applications
Cu-W Sintered is designed for critical electrical and mechanical applications where both conductivity and arc resilience are required. Typical uses include:
- Resistance welding electrodes and electrode components.
- Electrical discharge machining (EDM) electrodes.
- Circuit breaker contacts and arcing tips.
- Heavy-duty make-and-break contacts in industrial switching systems.
Extended Overview
Cu-W Sintered brings together the high electrical and thermal conductivity of copper with the arc-resistant and non-welding properties of tungsten. This combination addresses the core performance needs of electrodes and contact materials exposed to high currents and arc phenomena. Manufactured through a controlled sintering process, the alloy maintains a homogeneous microstructure that supports repeated arcing and mechanical stress without significant degradation. Its application spectrum includes resistance welding tooling, EDM, circuit protection devices and industrial switching equipment where both conductivity and durability influence uptime and lifetime.
Engineering Note
Cu-W Sintered is intended for use in high current, high arc exposure environments. Design engineers should validate component performance through application-specific testing before final specification. For customized alloy variants, shapes or tolerances, contact AMPCO METAL technical support.
