1/4″ (.250″) Copper Square Bar is manufactured from Alloy 110 (C11000), commercially pure electrolytic tough pitch (ETP) copper, and produced to ASTM B187 specifications for rods, bars, and shapes. The 1/4″ (.250″) square bar features uniform dimensions along its entire length, providing excellent electrical and thermal conductivity, corrosion resistance, and ductility. ETP copper ensures high purity and consistent quality, making this bar ideal for electrical, mechanical, and general industrial applications requiring reliable performance and formability.
Applications:
C110 Copper Square Bar is commonly used in electrical, mechanical, and industrial applications, including:
• Electrical bus bars, grounding components, and conductors
• Fabrication of connectors, terminals, and wiring systems
• Plumbing, HVAC, and piping applications requiring corrosion-resistant copper
• Decorative and architectural elements
• Machined or fabricated parts for industrial and manufacturing use
Advantages:
• High conductivity: Excellent electrical and thermal performance
• Corrosion resistant: Naturally resists rust and oxidation
• Ductile and formable: Easy to bend, shape, or machine without cracking
• Consistent quality: ETP copper ensures reliable performance and purity
• Versatile usage: Suitable for both functional and decorative applications
Summary:
The 1/4″ (.250″) C110 Copper Square Bar is a high-purity, corrosion-resistant copper bar manufactured to ASTM B187 standards. Its uniform square profile, superior conductivity, and ease of fabrication make it ideal for electrical, mechanical, industrial, and decorative applications requiring durability and reliable performance.
