Copper Target[2]

Updated: 2026-09-20

Overview

Copper Target is a high-purity metallic material specifically designed for physical vapor deposition (PVD) processes. It is widely used in industries requiring thin-film coatings due to its superior electrical and thermal conductivity. The target is typically manufactured from 99.99% pure copper to ensure optimal performance in vacuum deposition systems. Copper Targets are essential in the production of electronic components, solar panels, and decorative coatings. Their ability to form uniform, adherent films makes them indispensable in advanced manufacturing processes. The material's compatibility with various substrates further enhances its versatility in industrial applications.

Physical and Chemical Properties

Copper Target exhibits outstanding physical properties, including a density of 8.96 g/cm³ and a melting point of 1085°C. Its high ductility allows for precise shaping into various target geometries required for different deposition systems. The material's reddish-brown metallic luster is characteristic of its pure form. Chemically, copper is relatively stable but can oxidize when exposed to moist air over time. It is insoluble in water but dissolves in strong acids like nitric and sulfuric acid. These properties necessitate proper storage and handling to maintain the target's performance characteristics.

Main Applications

The primary application of Copper Target is in the semiconductor industry, where it's used for creating interconnects in integrated circuits. Its excellent conductivity makes it ideal for microelectronic applications requiring minimal signal loss. The target is also crucial in the production of thin-film solar cells, where it helps form efficient electrical pathways. Other significant uses include decorative coatings for architectural glass and consumer electronics, where copper's distinctive color and properties are valued. In research and development, Copper Targets are employed in various surface engineering and materials science experiments.

Safety and Storage

While copper is generally considered safe to handle, proper precautions should be taken when working with Copper Targets. Dust generated during machining or handling should be avoided, as inhalation can cause respiratory irritation. Appropriate personal protective equipment, including gloves and safety glasses, is recommended. Storage conditions significantly impact the target's shelf life and performance. Targets should be kept in dry, inert environments to prevent oxidation. Vacuum-sealed packaging with desiccants is commonly used for long-term storage, especially for high-purity targets intended for critical applications.

B2B Procurement Guide

When procuring Copper Targets, buyers should prioritize purity levels, typically requiring 99.99% (4N) or higher for most industrial applications. The target's dimensions and bonding method (bonded or unbonded) should match the specific requirements of the deposition system being used. Lead times can vary significantly based on target size and customization requirements, so advance planning is recommended. Buyers should request material certificates and performance data from suppliers to ensure quality consistency. For large-volume purchases, establishing long-term supply agreements can help stabilize pricing and availability.
