Description

Dross, Copper Base Alloy is a by-product material generated during the melting and processing of copper and its alloys. This material holds significant value as a secondary raw material for metal recovery and recycling processes. It is primarily utilized by foundries, metal refiners, and manufacturers in the metallurgical and recycling industries seeking to reclaim valuable metallic content.

Application

• Copper and Alloy Recovery: As a key feedstock for secondary smelters and refiners to recover copper, tin, zinc, and other valuable metals.
• Foundry Operations: Re-introduction into melting furnaces for charge optimization and yield improvement in brass, bronze, and other copper alloy production.
• Abrasives Manufacturing: Processing into granules for use in abrasive blasting and surface preparation media.
• Construction Materials: Incorporation into specialized cementitious products or aggregates for density and radiation shielding properties.
• Chemical Industry: As a source material for producing copper salts, oxides, and other copper-based compounds.
• Welding and Brazing: Used in the production of certain filler metals and fluxes.

Quality Control

Our Copper Base Alloy Dross is sourced and processed under controlled conditions to ensure batch-to-batch consistency. Material is characterized for its key metallic content to meet specific customer requirements for recycling efficiency. A Certificate of Analysis (COA) detailing metal assay (typically via XRF or ICP analysis), moisture content, and physical description is provided with each shipment to ensure transparency and suitability for your process.

Storage

Preserve in a tightly closed container, protected from light. Store in a dry, well-ventilated area at ambient temperature (15-25°C). Keep away from strong acids and oxidizing agents. As a metallic material, it is generally stable under these conditions.
