Overview
Red Copper Square Bar, also known as pure copper square bar, is a high-purity copper product with a minimum copper content of 99.9%. It is widely recognized for its excellent electrical and thermal conductivity, making it a preferred material in electrical and industrial applications. The material is characterized by its reddish-brown appearance and is available in various sizes and thicknesses to meet different industrial requirements. Its high ductility allows for easy machining and fabrication, while its corrosion resistance ensures longevity in various environments.
Physical and Chemical Properties
Red Copper Square Bar exhibits outstanding physical and chemical properties, including a density of 8.96 g/cm³ and a melting point of 1085°C. Its high electrical conductivity (100% IACS) and thermal conductivity make it ideal for electrical and heat transfer applications. The material is also highly resistant to corrosion, particularly in non-oxidizing environments. It is insoluble in water and most organic solvents, but it can react with oxidizing acids and ammonia. Its ductility and malleability allow it to be easily formed into various shapes without cracking.
Main Applications
Red Copper Square Bar is extensively used in electrical engineering for busbars, transformers, and switchgear components due to its superior conductivity. It is also employed in construction for roofing, plumbing, and decorative elements. In industrial settings, the material is used for heat exchangers, condensers, and other thermal management systems. Its corrosion resistance and durability make it suitable for marine and chemical processing applications. Additionally, it is used in artistic and architectural projects for its aesthetic appeal.
Safety and Storage
While red copper is non-toxic, proper safety measures should be taken during machining to avoid inhalation of copper dust, which can cause respiratory irritation. Use of personal protective equipment (PPE) such as gloves and masks is recommended. Storage should be in a dry, well-ventilated area to prevent oxidation and contamination. Avoid contact with corrosive substances, including acids and ammonia, which can degrade the material over time. Proper handling and storage ensure the longevity and performance of the copper bars.
B2B Procurement Guide
When procuring Red Copper Square Bar, verify the purity level (C11000 grade ensures 99.9% copper content) and request mill test reports for quality assurance. Check dimensions and tolerances to ensure they meet your project requirements. Consider the surface finish, as some applications may require polished or coated bars. Compare prices from multiple suppliers, but prioritize quality and reliability over cost. Establish long-term relationships with reputable suppliers to ensure consistent quality and timely delivery.
