Beryllium copper C17200 is a high-performance alloy renowned for its exceptional mechanical properties, making it a preferred choice in various demanding applications. The alloy is a copper-beryllium composite, typically comprising about 1.8% to 2.0% beryllium. This combination results in outstanding mechanical characteristics, including high strength, excellent fatigue resistance, and notable hardness. This article explores the mechanical properties of beryllium copper C17200, discussing its relevance in industrial applications.
Kuvvet
One of the defining features of C17200 is its impressive tensile strength, which can range from 480 MPa to over 700 MPa, depending on the temper and processing methods used. This strength is comparable to some steels, yet the alloy maintains a much lower density, making it advantageous in applications where weight is a consideration. The high tensile strength allows for the production of lightweight components that can withstand substantial loads, making C17200 ideal for aerospace and automotive applications where structural integrity is critical.

C17200 exhibits excellent fatigue resistance, which is vital in applications subjected to cyclic loading. The alloy can endure repeated stress without significant degradation in performance, making it suitable for components such as springs, fasteners, and electrical connectors. This resistance to fatigue is primarily attributed to the beryllium content, which enhances the alloy’s microstructure, allowing it to better absorb and dissipate energy during stress cycles.
Ductility and Workability
Despite its high strength, beryllium copper C17200 retains commendable ductility. The alloy can be easily formed, machined, and fabricated into various shapes, allowing for versatility in design and application. This combination of strength and ductility makes C17200 an excellent candidate for precision parts where tight tolerances are required. Manufacturers often utilize processes like forging, rolling, and extrusion to create components tailored to specific applications.
