Its immunity to hydrogen embrittlement at elevated temperatures makes it particularly valuable for high-performance electrical applications.
Copper 110: The Basics
What is Copper 110?
Copper 110, or Electrolytic Tough Pitch (ETP) copper, contains 99.9% pure copper with approximately 0.04% oxygen content. This widely used copper grade is manufactured through an electrolytic process that creates a rigid, durable material. The presence of oxygen distinguishes it from oxygen-free copper grades while maintaining excellent conductivity properties.
Critical Characteristics of Copper 110
The material exhibits outstanding electrical conductivity at 100% IACS (International Annealed Copper Standard) and superior thermal conductivity. Its mechanical properties vary by temper, with ultimate tensile strength ranging from 32 to 50 ksi and yield strength from 10 to 45 ksi.
The material demonstrates excellent formability, with elongation rates reaching 55% in the صلب conditions. Its melting point ranges between 1,949-1,981°F, and it maintains a consistent density of 0.321 lb/in³.
Common Applications of Copper 110
Due to its versatile properties, the material serves diverse industrial purposes. Primary applications include electrical components like transformers, switch gears, and magnets. It’s commonly used for plumbing hardware, wiring, skylight frames, and gutters in construction.
Critical Differences Between Copper 101 and Copper 110
Electrical Conductivity: Which Copper Alloy Performs Better?
Both grades demonstrate excellent electrical conductivity, with Copper 101 reaching 100% IACS. Copper 110 maintains comparable performance at 101% IACS, making it the highest conductor among metals except silver. The minimal difference in conductivity makes both suitable for electrical applications.
الموصلية الحرارية: How Do Copper 101 and Copper 110 Compare?
While both alloys effectively conduct heat, Copper 110’s specific composition makes it particularly suitable for heat exchange applications and thermal management systems.
المقاومة للتآكل: Which Alloy Offers Greater Durability?
Copper 110 forms a protective patina when exposed to environmental elements, providing excellent corrosion resistance in most environments. However, it should not be used with certain materials, such as acetylene, ammonia, chromic acid, or mercury.
قابلية العمل: How Easily Can These Alloys Be Processed?
Copper 110 demonstrates good elasticity and plasticity, making it ideal for complex shapes. Copper 101 shows excellent machinability but limited ductility compared to Copper 110. The cutting forces required for Copper 101 (800-1200N) are lower than those needed for Copper 110 (1000-1500N).
Mechanical Strength: Comparing the Strength of Copper 101 and 110
Copper 101 exhibits higher strength (250-350 MPa) than Copper 110 (150-220 MPa). In terms of hardness, Copper 101 measures 70-90 HB, while Copper 110 ranges from 45-60 HB. This makes Copper 101 more suitable for applications requiring higher mechanical strength.
