tellurium copper

1. Highly Conductive Copper-Based Alloys: These are primarily known as DT copper alloys, recognized for their outstanding conductivity, thermal properties, and resistance to corrosion and arcing. They excel in electrical applications due to their superior performance and meet stringent regulations regarding hazardous substances. With excellent hot and cold processing attributes, these alloys are a viable alternative to silver copper, promising vast potential in various industries due to their high conductivity and other beneficial properties.

2. High-Strength Magnesium Copper-Based Alloys: Identified generally as MDT alloys, these are known for their high conductivity and excellent mechanical properties. They are particularly prevalent in the high-speed rail network and other industrial applications. These alloys are still largely in the developmental stage in some countries but have seen significant use in others, particularly in electrical components like connectors and commutators.

3. Easy-Cutting Type Phosphate Copper-Based Alloys: Commonly referred to as PDT alloys, these are celebrated for their high productivity and cost-effectiveness. They are extensively used in the chemical, mechanical, and welding industries. Due to their superior cutting performance, they are also used to manufacture various cutting devices and components.

C14500 copper alloy, a relatively new material with 0.40-0.70% bismuth and 0.004-0.012% phosphorus, exhibits excellent machinability, conductivity, and corrosion resistance. It’s been adopted in many developed countries for use in precision electronic components, advanced electromechanical parts, and other applications.

The market recognizes the superior performance of these copper alloys, though it also acknowledges the high processing costs and strategic nature of the materials. Initiatives in regions like Luoyang, Sichuan, and Shenyang are underway to explore and expand the market potential.

Alloy Product Testing Plan:

1. Casting Process Parameters: This involves exploring optimal casting processes, using different crystallizers and casting speeds to compare ingot performance and establish the best parameters. Efforts are also made to reduce costs and material usage during the production process.

2. Extrusion and Stretching Process Parameters: The focus here is on optimizing the extrusion and tensile processes to meet performance requirements without annealing. This includes considering the material hardness, mold, and equipment performance to ensure successful manufacturing while improving product surface quality through techniques like water seal extrusion.
