Frequently Asked Questions (FAQ)
Q1: What is the primary composition of C17300 Beryllium Copper?
C17300 Beryllium Copper primarily consists of 1.8% to 2.2% Beryllium (Be), 0.2% to 0.6% Lead (Pb), and at least 0.2% Cobalt (Co) + Nickel (Ni), with the remaining balance being Copper (Cu).
Q2: Why does C17300 offer outstanding cutting performance?
The addition of a small amount of Lead (0.2-0.6%) acts as a chip breaker and lubricant during machining. This drastically improves the free-cutting performance, making it highly suitable for high-speed automatic lathe processing.
Q3: What are the key physical properties of C17300?
C17300 has a density of 8.3 g/cm³, an elastic modulus of 128 GPa, thermal conductivity of 105 W/(m·K), and a melting range of 870–980℃.
Q4: In what industries is C17300 Beryllium Copper commonly used?
It is widely applied in precision electronic connectors, pins, aerospace components, automotive industrial parts, elastic elements, and various wear-resistant structural components.
Q5: Does C17300 offer good corrosion resistance?
Yes, C17300 exhibits excellent corrosion resistance alongside high strength, fatigue resistance, and good electrical conductivity, ensuring reliable performance in harsh environments.
