Material Overview
Beryllium copper is a high-performance copper alloy known for its exceptional strength, elasticity, thermal and electrical conductivity, non-magnetic and anti-spark properties, and corrosion and wear resistance.
Available in 0.5–5.0 mm sheets, it features uniform structure and flat surfaces. Its thin-sheet form is ideal for precision manufacturing.
Laser processing, with its high accuracy, low heat impact, non-contact operation, and flexibility, perfectly addresses beryllium copper's processing challenges-hard to cut, heat-sensitive, and precision-dependent-making it a preferred method for high-end component production across electronics, new energy, precision molds, aerospace, and medical & explosion-proof applications.
Key Material Properties
►Strength & Elasticity: Tensile strength 1200–1450 MPa, hardness 380–450 H (HRC36–42), high elastic limit, rebound ≥96%, fatigue resistance over millions of cycles.
►High Conductivity: Electrical conductivity 18–60% IACS, thermal conductivity 105–200 W/m·K, balancing strength and heat dissipation.
►Dimensional Stability: Minimal deformation between -196 °C to 250 °C, low elastic hysteresis, and stress relaxation.
►Non-Magnetic & Explosion-Proof: No magnetic interference (safe for MRI or precision instruments), spark-free under impact.
►Corrosion & Wear Resistance: Resistant to atmospheric, freshwater, and seawater corrosion, wear, electrical arc, and low electrochemical erosion.
►Processing-Friendly: Soft state allows stamping, bending, deep drawing; hardened state offers rigidity and smooth surfaces (Ra ≤ 1.6 µm).
Applications
Electronics & Electrical: Microstructures and precision spring components
►Thin beryllium copper sheets (0.1–1 mm) can be laser cut, drilled, or engraved with micron-level accuracy, burr-free edges, and minimal stress, ideal for 5G, semiconductors, and miniaturized consumer electronics.
►RF connectors & terminals: Complex laser-cut shapes and micro-holes for 5G base station springs, SIM card contacts, battery terminals, achieving ±0.02 mm precision and reliable million-cycle performance.
New Energy Vehicles: High-voltage connections and thermal components
►High-voltage connector springs and busbars (1–2 mm) processed via laser cutting and precision bending, stable conductivity from -40 °C to 150 °C, vibration-resistant, anti-loosening for 800 V platforms.
►Safety & sensor springs: Airbag triggers, ABS sensor springs (0.5–1 mm), laser cut and age-hardened, fatigue life ≥10⁷ cycles.
Aerospace & Defense: Non-magnetic, explosion-proof, extreme environment components
►Aircraft instruments and navigation: Non-magnetic springs and thin sheets with precise laser-cut micro-holes, stable under high/low temperatures.
►Satellite & spacecraft springs: Solar panel deployment springs, contact points, lightweight, high reliability, radiation-resistant.
Laser Processing Advantages for Beryllium Copper
►Ultra-High Precision: Laser spot ≤0.1 mm, cutting and drilling ±0.02 mm, perfect for micro-scale components.
►Low Thermal Impact: Non-contact, short heat exposure preserves elastic and conductive properties.
►Burr-Free & Stress-Free: Smooth edges without secondary finishing, avoids deformation.
►Flexible & Efficient: No molds required, ideal for small batches and multiple designs; micro-hole speed 5–10× faster than traditional drilling.
►Safe & Eco-Friendly: Minimizes dust spread, meeting environmental and occupational safety standards.
