Product Overview

What are Beryllium Copper C17200 Screws?

Beryllium Copper C17200 screws are high-performance fasteners manufactured from a copper-beryllium alloy (UNS C17200) conforming to ASTM B194 and ASTM B196 standards. This alloy is renowned for its exceptional combination of high strength, electrical and thermal conductivity, and non-magnetic properties. C17200 screws are precipitation-hardened to achieve tensile strengths up to 1380 MPa, making them ideal for demanding applications where both mechanical and electrical performance are critical.

Beryllium Copper C17200 screws are widely specified in aerospace, electronics, oil & gas, and precision instrumentation due to their outstanding fatigue resistance, galling resistance, and ability to maintain properties at elevated temperatures. They are also non-sparking, making them suitable for hazardous environments.

Material Chemistry

Beryllium Copper C17200 Chemical Composition

Beryllium Copper C17200 Screws are produced from either tin-stabilized Naval Brass C46400 or aluminium-nickel-iron Aluminium Bronze C63000, with elemental limits per ASTM and MIL-B-24059. Tin (0.5–1%) in Naval Brass prevents dezincification in seawater; aluminium and nickel additions in Al Bronze C63000 provide non-sparking ATEX Zone 1 compliance.

Why Beryllium Copper C17200 Alloy Composition Matters for Screws

Be (1.8–2.0%) — Precipitation Hardening
Beryllium content enables C17200 screws to be precipitation hardened, achieving tensile strengths up to 1380 MPa while retaining ductility and fatigue resistance. This is critical for high-load, high-cycle applications.
Cu (97.9% min) — Conductivity & Non-Magnetic
High copper content ensures excellent electrical and thermal conductivity, making these screws ideal for electrical, electronic, and RF applications where signal integrity and non-magnetic properties are required.
Trace Elements — Corrosion & Wear Resistance
Small additions of cobalt, nickel, and iron improve corrosion resistance and wear properties, ensuring long service life in harsh environments and reducing the risk of galling during assembly.
