COBALT-COPPER MASTER ALLOY

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

Component Identity Information:

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Cobalt-Copper master alloy (CuCo10) is an intermetallic compound of copper (Cu) and cobalt (Co). The alloy consists of a copper-rich solid solution matrix with finely distributed cobalt-rich intermetallic phases. The primary phase present is Cu solid solution with dissolved cobalt, forming a homogeneous structure with minimal segregation.

15. CRITICAL NOTICES AND BEST PRACTICES

CRITICAL NOTICES:

1. Cobalt Content: Nominal composition is 10% Co. Final alloy cobalt content typically 0.5-5% depending on application.

2. Narrow Melting Range: The 20°C melting range ensures rapid dissolution and homogeneous distribution.

3. Beryllium-Free Alternative: Provides high strength and wear resistance without toxicity concerns.

4. Oxidation Prevention: Store in dry conditions to prevent surface oxidation.

5. High Temperature Resistance: Excellent softening resistance at elevated temperatures.

6. Safety: Cobalt powder is flammable. Avoid dust formation when processing.

BEST PRACTICE RECOMMENDATIONS:

Storage:

• Store in a dry, well-ventilated area (5-40°C)

• Keep away from acids, salts, and strong oxidizers

• No shelf life limitation under proper conditions

Handling:

• Use protective goggles, gloves, and dust mask when processing

• Use appropriate lifting equipment for pallets

Melting:

• Add 2-10% CuCo10 to the melt

• Maintain temperature 1480-1550°C

• Stir thoroughly for homogeneity

• Expected cobalt recovery >95%

Waste Management:

• Dispose through licensed recycling facilities

• Do not discharge into water bodies
