Product Overview

What are Beryllium Copper C17200 Nuts?

Beryllium Copper C17200 nuts are high-performance fasteners manufactured from a copper-beryllium alloy (UNS C17200) conforming to ASTM B194 and ASTM B196. This precipitation-hardened alloy contains 1.8-2.0% beryllium, providing a unique combination of high strength (up to 1380 MPa), excellent electrical and thermal conductivity, and outstanding resistance to stress relaxation and galling.

Beryllium Copper C17200 nuts are non-magnetic, spark-resistant, and maintain their mechanical properties across a wide temperature range. They are widely specified for critical bolted joints in electrical, aerospace, oil & gas, and instrumentation applications where conventional copper alloys or stainless steels are inadequate.

Material Chemistry

Beryllium Copper C17200 Chemical Composition

Beryllium Copper C17200 Nuts 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 Nuts

Beryllium (1.8–2.0%) — Strength & Stress Relaxation
Beryllium transforms copper into a precipitation-hardened alloy, enabling C17200 nuts to achieve tensile strengths up to 1380 MPa and resist stress relaxation at elevated temperatures, making them ideal for bolted joints in electrical and aerospace assemblies.
Copper (97.9% min) — Conductivity & Non-Magnetic
The high copper content ensures excellent electrical and thermal conductivity, while the alloy remains non-magnetic and spark-resistant, critical for electrical switchgear and hazardous area applications.
Trace Elements — Corrosion Resistance
Low levels of cobalt, nickel, and iron enhance corrosion resistance in industrial and marine atmospheres, ensuring long-term reliability of fastened joints.
